Mud pump liner selection in today"s drilling operations seldom (at best) considers electrical implications. Perhaps, with more available useful information about the relationships between mud pump liner size and operational effects on the electrical system, certain potential problems can be avoided. The intent of this paper is to develop those relationships and show how they affect an electrical system on example SCR rigs.Introduction

There, seems to be little consideration for the relationships between liner size and demand on a rig"s engine/generator set(s). Yet, consideration for this relationship can prove to be very helpful to drillers and operators in efficiency of a rig"s electrical system. In order to develop the relationships and help drillers and operators understand the importance of each, relationships between liner size, pump speed, pump pressure, and electrical power will be developed. Only basic physical laws will be used to develop the relationships; and, once developed, the relationships are readily applied to realistic examples utilizing a mud pump manufacturer"s pump data. Finally, conclusions will be drawn from the examples.DEVELOPMENT OF RELATIONSHIPS BASIC RELATIONSHIPS

where HHP= Hydraulic horsepower, GPM = Mud pump volumetric flow rate in gallons per minute, and PST Mud pump output pressure in pounds peer square inch.

Hydraulic horsepower is reflected to the mud pump motor via a multiplier for mechanical efficiency. it follows that motor horsepower is then represented by

A mud pump is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi (52,000 kPa)) down the drill string and back up the annulus. A duplex mud pump is an important part of the equipment used for oil well drilling.

Duplex mud pumps (two piston/plungers) have generally been replaced by the triplex pump, but are still common in developing countries. Two later developments are the hex pump with six vertical pistons/plungers, and various quintuplex’s with five horizontal piston/plungers. The advantages that Duplex mud pumps have over convention triplex pumps is a lower mud noise which assists with better Measurement while drilling and Logging while drilling decoding.

Use duplex mud pumps to make sure that the circulation of the mud being drilled or the supply of liquid reaches the bottom of the well from the mud cleaning system. Despite being older technology than the triplex mud pump, the duplex mud pumps can use either electricity or diesel, and maintenance is easy due to their binocular floating seals and safety valves.

A mud pump is composed of many parts including mud pump liner, mud pump piston, modules, hydraulic seat pullers, and other parts. Parts of a mud pump:housing itself

Duplex pumps are used to provide a secondary means of fuel transfer in the event of a failure of the primary pump. Each pump in a duplex set is sized to meet the full flow requirements of the system. Pump controllers can be set for any of the following common operating modes:Lead / Lag (Primary / Secondary): The lead (primary) pump is selected by the user and the lag (secondary pump operates when a failure of the primary pump is detected.

Alternating: Operates per Lead / Lag (Primary / Secondary) except that the operating pump and lead / lag status alternate on consecutive starts. A variation is to alternate the pumps based on the operating time (hour meter) of the lead pump.

The article presents selected technical issues relating to drilling performed by a drillship, one type of drilling rigs. Basic problems encountered in the main function of such rigs − drilling a well − are failures of mud pumps. The authors investigate these pumps in operational conditions, aiming at development of a system for monitoring the technical condition of these pumps. Work on a diagnostic system is in progress that will permit to predict the condition of mud pump valves well in…Expand

This paper aims to develop a theoretical model in order to study the influence of the drilling fluid flow velocity on mud pumps valves wear. Mud pumps are operated at a high flow rate of the drilling fluid. The mud pumps valves come under the action of the abrasive drilling mud, which leads to their early wear. For the analysis of the velocity field in the flow area of the interspace between valve body and seat is used the finite element method. Research has shown that the maximum velocity…Expand

Mud pumps are reciprocation plunging devices that are specifically designed to pump the drilling fluid down the drill string and back up the annulus. These are large pumps used on drilling rigs. However, some of these pumps are also used in construction sites for transferring the concrete mixture. Most pumps used in drilling rigs are far too powerful for such needs.

Mud pumps used in drilling rigs serve a variety of purposes. The primary job is usually pushing the mixture into the fractured earth’s surface, but they are also used to clear out the sludge and mud extracted from the drilling hole. The most-used pumps at a drilling rig are triplex and quintuplex pumps. Both are designed with specific applications in mind. Quintuplex pumps are more powerful and sophisticated than the others.

The major benefit of mud pumps is their efficiency with the immense amount of strength generated by them, often exceeding 2700bhp with a pressure of 20,000psi along with the flow rate of 51.3 bpm. Such figures illustrate the strength of high-power mud pumps.

Good-quality mud pumps have a suction valve retainer with a unique design. The superior valve design significantly reduces fluid end erosion. This directly impacts the life of the fluid end, making it last much longer than it otherwise would. Superior-quality mud pumps are also able to provide increased fluid capacity at slower speeds that raises the longevity of the major parts and components. Quintuplex pumps are extremely effective whenever under high rod-loads.
