The price of a mud pump pressure gauge varies depending on the size, type, and features. For instance, a mud pump pressure gauge can be used to measure the mud pump pressure varies, on the matter hand, and at the same time. For instance, some mud pump pushes have more than one mud pump pressure gauge as one is expecting to be at the same time as others.

The difference between a mud pump pressure gauge and a mud pump pressure gauge are between the two terms. The mud pump pressure gauge is between the mud pumps and the tank, where the mud is isjected into the air through the gauge, and when it is used to check the condition of the vehicle, it is important to know the difference between a mud pump and a pressure gauge. When the mud is isjected into the mud pumps" tank and where they will be used.

If there is no signal output or output over value during the drilling process of the pressure sensor, first check whether the extension cable is open or through. When the pressure reading is not correct, first check whether the sensor is lack of hydraulic oil or whether there is air bubble in the oil circuit. In case of oil shortage, the manual pump shall be used for oil filling, and if there are bubbles, the bubbles shall be discharged.

If it is suspected that the pressure sensor is faulty, the connection between the sensor and the piston pressure gauge can be removed. According to the engineering range of the sensor, when the input voltage is zero and the full range, the signal current should be about 4 and 20 mA respectively, otherwise the sensor is faulty and sent back to the company for maintenance.

There are two potentiometers in the sensor that can be used to adjust the output zero point and full range value of the sensor. Unplug the Hirschmann connector and the rear cover of the sensor, and you can see that 504 × is the zero point adjustment, and the other one is the full range adjustment. Connect the current and standard pressure source, adjust 504 × potentiometer when the pressure is zero, and the output of the sensor is 4mA, and then adjust the pressure source to the full range pressure Adjust the other potentiometer to make the sensor output 20mA. Repeat the adjustment for two or three times.

Hydraulic data transmission requires sensitive pressure sensors capable of enduring high pressures. This is particularly true when used in measurement while drilling (MWD) applications.

MWD has become a standard application, especially for offshore directional drilling. Real-time data collection is essential for measuring the trajectory of the hole as it is drilled. For this purpose, various sensors are mounted on the drill head to provide information about the drilling environment in real time. Inclination, temperature, ultrasound and also radiation sensors are used. These various sensors are physically or digitally connected to a logic unit that converts the information into binary digits. The downhole data are transmitted to the surface via mud pulse telemetry. In addition to monitoring and controlling the drilling process, the data are used for further aspects, including:

Mud pulse telemetry is a binary coding transmission system used with liquids. This is achieved by a valve that varies the pressure of the drilling mud within the drill string and thus converts the recordings of the sensors mounted on the drill head into pressure pulses. The pulsations reach the surface via the drilling mud. The pressure pulses are measured on the surface by a pressure transmitter and converted into an electrical signal. This signal is transmitted to a computer and digitized.

STS provides offshore directional drilling companies with analog pressure transmitters optimized for mud pulse telemetry. The sensors have to meet high demands: They must be extremely sensitive in order to reliably register even the smallest pressure differences. At the same time, the sensors must withstand pressures of up to 1,000 bar. Very high pressures are required to power the drill head in very deep drill holes. The pressure transmitters used for mud pulse telemetry on the surface are also exposed to these forces.

In addition to the high sensitivity, very fast response times are required to ensure good data communication in real time. In order to exclude falsified measurement results, the measuring instrument should be low-noise. The mud pumps in particular can cause the most signal noise in drilling applications. The drive of the drill is another source of interference. For this reason, analogue sensors with a 4 – 20 mAoutput signal are the best solution for mud pulse telemetry.

Since 1990, Quartzdyne has designed and manufactured the industry-standard quartz pressure transducer for the downhole oil and gas industry. Our sensors are world-renowned for providing accurate, low drift, high resolution data in the most extreme conditions. Typical calibrations can result in less than ±1.0 psi in error for a 10 kpsi transducer across the calibrated temperature range.

The feasibility of applying delay pressure detection method to eliminate mud pump pressure interference on the downhole mud pressure signals is studied. Two pressure sensors mounted on the mud pipe in some distance apart are provided to detect the downhole mud continuous pressure wave signals on the surface according to the delayed time produced by mud pressure wave transmitting between the two sensors. A mathematical model of delay pressure detection is built by analysis of transmission path between mud pump pressure interference and downhole mud pressure signals. Considering pressure signal transmission characteristics of the mud pipe, a mathematical model of ideal low-pass filter for limited frequency band signal is introduced to study the pole frequency impact on the signal reconstruction and the constraints of pressure sensor distance are obtained by pole frequencies analysis. Theoretical calculation and numerical simulation show that the method can effectively eliminate mud pump pressure interference and the downhole mud continuous pressure wave signals can be reconstructed successfully with a significant improvement in signal-to-noise ratio (SNR) in the condition of satisfying the constraints of pressure sensor distance.

In measurement while drilling (MWD), various downhole signals will be transmitted to the surface in real time for instructing the drilling operation. One of the most common methods of transmitting the measured downhole information to the surface is through mud pressure pulses produced by mechanical modulation of a mud siren in MWD tools and transmitted at acoustic speed in the mud flow. The mud siren generates mud continuous pressure wave signals with complex modulation methods to produce higher data rates. When transmitting the mud pressure signals, there will be a lot of pressure noise and interference, among which the mud pressure fluctuation generated by the mud pump contributes to the largest influence. The mud pump pressure interference is related to the pump stoke rate which includes fundamental component and harmonic component. When the mud pump is in imbalance operation mode caused by sealing problem or in abnormal working status, some higher harmonic amplitude will become very large. Although the pressure dampers are equipped on mud pump pipe, the pressure fluctuation generated by mud pump reaches or exceeds the downhole signal strength detected in the stand pipe [1]. These higher harmonics will enter the frequency band of mud pressure signal and thereby create great interference that cannot be eliminated by conventional signal processing method, leading to the great decrease of signal-to-noise ratio (SNR) of signal and affecting extraction of the MWD signals. Many studies had been done to eliminate the pump interference. Marsh and others proposed the matched filter method which treated mud pump interference as random noise and calculated the autocorrelation coefficient to eliminate the mud pump pressure interference [2]. However, the pump interference is a kind of system interference rather than random noise, so the conclusions of the method needed further discussion. Brandon and others proposed an adaptive compensation method which uses extracted interference component in the signal and automatically adjusts strength of the interference component to eliminate the pump pressure interference impact on the signal [3], but the effect was limited. Some literatures [4–7] introduced the delay pressure detection technique and built a mathematical model, being fitted to the single-frequency signal with pressure sensors distance of quarter signal wavelength, for eliminating the mud pump pressure interference. Because components of many frequencies are contained in mud continuous pressure wave signals, the mathematical model presented in those literatures cannot be applied in reconstruction of actual mud continuous pressure wave signals. Based on transmission path analysis of mud pump pressure interference and downhole mud pressure signals, the authors established the mathematical model in time domain for processing mud continuous pressure wave signals according to the fundamental mathematical principle of delay pressure detection method and then studied the reconstruction method of mud continuous wave signals in both time domain and frequency domain and constraints of the distance between pressure sensors.

The delay pressure detection method uses two pressure sensors being some distance apart on the mud pipe to detect and process the mud pressure signal; Figure 1 shows the schematic figure of mud pressure signal detection system. Two pressure sensors, A and B, having distance between each other, are equipped in a straight pipe between wellhead and mud pump. The pressure signals received by two sensors contain downhole signal (mud pressure signal) , downhole random noise , and mud pump pressure interference . The transmission direction of pump pressure interference is opposite to that of downhole signal. Suppose that the propagation velocity of the mud pressure wave is and the pressure wave transmission time between sensors A and B is .

Suppose that is unit impulse response of the linear system . When the signal is being transmitted through the linear system [8], signals received by the pressure sensors A and B can be expressed as

According to (5), the time-domain solution of the system frequency response can be described as the reconstruction of the downhole signal after the delay pressure detecting signal is passed through a signal recovering system with frequency transfer function .

Considering that the maximum frequency of mud continuous pressure wave signal in transmission will be dozens of hertz (Hz), the signal frequency is lower and limited. In limited frequency band, the signal attenuation in amplitude will keep unchangeable when mud continuous pressure wave signal passes the straight pipe between pressure sensors A and B, so the pipe can be seen as an undistorted transmission system and regarded as an ideal low-pass filter. The frequency domain transfer function of the system can be described as

Equations (13) and (11) have the same structure, so the essence of signal reconstruction process in time domain is to make the delay pressure detecting signal pass through a closed-loop delay feedback system with recursive structure.

The straight pipe between pressure sensors A and B will cause pressure signal attenuation. According to the transmission characteristics of mud pressure wave [11], the attenuation coefficient of pressure signal or the amplitude ratio of mud pipe can be described as

where is the pipe length between pressure sensors A and B, is the attenuation index, is the volume fraction of gas in mud, is the volume fraction of solids in mud, is the bulk modulus of gas in mud, is the bulk modulus of liquid in mud, is the bulk modulus of solid in mud, is the bulk modulus of the mud pipe, is the internal diameter of the mud pipe, is the wall thickness of the mud pipe, is the Poisson’s ratio of the mud pipe, is the kinematic viscosity of mud, and is signal frequency.

Suppose that the mud is water-based mud. The computational conditions are listed as follows [12]: internal diameter of the mud pipe is 108.6 mm, wall thickness of the mud pipe is 9.2 mm, the mud kinematic viscosity is 20 mPa·, the pipe Poisson’s ratio is 0.3, volume fraction of gas in mud is 0.5%, volume fraction of solid in mud is 15%, the mud pipe bulk modulus is 210 GPa, and bulk modulus of water in mud is 2.04 GPa, bulk modulus of solid in mud is 16.2 GPa. If signal frequency of mud continuous pressure wave is , when the distance between pressure sensors A and B is less than , the pressure signal attenuation coefficient will be by numerical calculation. This means that transmission loss of mud pressure wave signal is very small and the attenuation coefficient will be close to 1 when the two sensors are nearer to each other.

If the maximum frequency of mud pressure signal spectrum is , there is . When the corresponding pole frequency falls into the passband of ideal low-pass filter, the pole frequency will be very likely to enter signal spectrum and generate great interference in the reconstruction of downhole signal. To avoid such situation, all the pole frequency values should be greater than the passband frequency of ideal low-pass filter. That is, .

Propagation velocity of the mud pressure wave in the mud pipe can be calculated according to the literature [13]. Take the mud pressure DPSK (differential phase shift keying) signal with carrier wave frequency of 24 Hz for example, the maximum frequency of signal spectrum is 36 Hz. When  Hz, we have  s. Furthermore, if the mud pressure wave velocity is  m/s, the corresponding distance between pressure sensors is  m.

The numerical simulation takes mud pressure DPSK signal as an example. According to the mathematical model of mud pressure DPSK signal [14], the signal can be formulated as . In the formula, carrier frequency is  Hz, signal amplitude is  Pa, and data code is . By analyzing the power spectral of mud pressure DPSK signal, the maximum frequency of signal spectrum is  Hz and the signal power is . Mud pump interference simulates multifrequency pressure pulsation generated by triplex pump with pump impulse rate 64 r/min, and the fundamental wave frequency is with harmonic orders 2 to 9. Therefore, the frequency changing range of pump interference is from to . Suppose that the fundamental wave and every harmonic wave amplitude are . The corresponding power density of fundamental wave or every harmonic wave is an impact function and the average power of the pump interference is

Figure 2 shows the signal waveform and the signal spectrum mixed with mud pump interference. It can be seen that the mud pressure DPSK signal is completely submerged in the pump interference in time domain and the signal spectrum is completely covered by mud pump interference frequencies.

Suppose that the signal acts on the at , has zero state response only, and the system output before is . Simulation result of the reconstructed signal by MATLAB programming is shown in Figure 3. It can be seen that the mud pump interference is eliminated after delay pressure detection from Figure 3(a); the reconstructed signal in Figures 3(b) and 3(c) are consistent with the mud pressure DPSK signal in Figure 2(a). In Figure 3(b), the numerical calculation result shows that the SNR of reconstructed mud pressure DPSK signal under condition of  ms is 72.4, which is about 657 times higher than that of existing pump interference. Numerical calculation and analysis show that the SNR of reconstructed mud pressure DPSK signal will be affected by the delayed time in time domain and the influence is listed in Table 1. The reason is that the set value of , participating in the recursive computation in (11), will be increased with the delayed time , but the influence is not notable. In Figure 3(c), the reconstructed mud pressure DPSK signal based on inverse Fourier transform method has no distortion in whole waveform and is better than the signal reconstructed by time-domain differential equation method in quality. However, both reconstruction methods can reconstruct downhole signal effectively.

(1) Theoretical analysis and numerical simulation show that delay pressure detection method can effectively eliminate mud pump interference and realize reconstruction or recovery of mud continuous pressure wave signals with greater SNR.

(2) To avoid the pole frequency entering into the signals frequency band in signal reconstruction, the distance between pressure sensors should be determined according to the highest signal frequency and the minimum wave velocity.

(3) According to the mathematical principle analysis of delay pressure detection method, it is only applied to eliminate special interference (mud pump pressure interference) whose transmitting direction is opposite to that of the downhole signal. For mud continuous pressure wave signal which is seriously affected by mud pump interference, this method has some inspiration effect on solving the problem of mud pump pressure interference.
