In order to solve low degree of work over automation, labor-intensive job dangerous, poor working environment issues, Shengji has developed a series of mechanical work over system, including workover automatic system, minor workover automatic system and snubbing operation equipment.

Oil well workover is a high-tech, high-risk work. The conventional oilfield workover rig has problems such complicated operating procedures and high labor intensity. Shengji, in cooperation with the Shengli Drilling Corporation, have designed an oilfield workover rig automation system.

The oilfield automatic workover rig has a high degree of automation adopting modular integration and advanced robot closed-loop control technology. It functions as self-diagnosis, leakage and short circuit protection and fault alarming, etc. It has remote monitoring capability.

The automatic workover rig greatly increases the automation of workover operations, reduces the number of operators, decreases workers’ labor intensity. The technology is advanced, safe and reliable.

The big difference between this type of flush-by rig and conventional flush-by unit is drawworks. Mechanical drawworks are adopted on ourflush-by rig.

Drillform’s 820 Workover Rig Catwalk offers fast cycle time and a high lift capacity. The unit has a simple set up, and features hydraulic kickers, indexers, and skate. The “no deck” design reduces overall weight and increases personnel safety by reducing fall risk. For ease of transport, there is a simple transition into transport mode with a pintle hitch. A telescoping ramp extends from 8’ to 20’ (optionally higher) floor heights, while an extended pipe channel accommodates Range II and Range III tubulars with up to 2,200 lb. lifting capacity, handling 2 ⅜” to 6” OD. The catwalk includes a pintle hitch for easy towing and is available in skid and towable versions. Now available in both skid and towable versions from World Petroleum Supply, Inc. located near Houston, TX.

The team at Drillform have been leading industry efforts to automate pipe handling since the late 1990s with their introduction of the TM series of Iron Roughnecks and PC series of catwalks, sold to Canrig/Nabors Industries in 2006. Drillform’s modern iron roughnecks are geared to address the challenges¬¬ facing drilling contractors associated with more powerful rigs, and the drilling of deeper and more horizontal wells.

To accommodate an industry trending towards longer and deeper well profiles, Drillform has introduced a family of hydraulic and pneumatic workover rig catwalks designed to increase the speed and efficiency of tubular handling.

The automatic workover rig is a new type of wellhead operation automation equipment developed for the lifting and lowering of oil pipes (sucker rods) in small oil and water well repair operations.

The automatic workover rig has made major breakthroughs in key technologies such as unmanned automatic operation at the wellhead, automatic pipe and rod transfer, electro-hydraulic servo control, and man-machine synchronization control. Various performance indicators have been verified by a large number of field tests.

At present, although some oilfield workover operations have adopted some automatic equipment, the unmanned operation of the wellhead has been realized, which has greatly reduced the labor intensity of workers, improved the operating environment, and improved the safety factor. But the tubing cannot swing with the pipe pusher when working in windy weather, the pipe pusher cannot accurately align the tubing with the coupling, which affects the reliability and stability of the automated operation. At the same time, there are many equipment movement mechanisms, which are distributed around the wellhead, resulting in manual intervention in the operation space, especially in the wellhead emergency rescue process, which will affect the efficiency of emergency rescue.

For the above disadvantages, Sanjack Company provides an automatic wellhead operation device for oilfield workover operations, which mainly realizes the accurate alignment of tubing couplings, improves the reliability and stability of automated operations, and secondly, through innovative design and reasonable layout of the components of the workover platform, the platform operation space is increased, which is convenient for manual operation and wellhead rescue operations.

The automatic wellhead operation device for automatic workover operation adopts the principle of electro-permanent magnet suction pipe, and design a set of mechanism that can swing freely under its own gravity to achieve accurate alignment of the tubing.

This automatic wellhead operation device improves the reliability and stability of automated operations. At the same time, through the innovative design and reasonable layout of the components of the workover platform, the structure is compact and simple, which increases the platform operation space and facilitates manual operation and wellhead rescue operations. Accurate movement positioning achieves precise and reliable workover.

(1) This device is based on the power and lifting conditions of the existing workover rigs. Through the hydraulic control transformation of elevators and hydraulic clamps, the development of automatic positioning manipulators and manipulators, and the selection of pneumatic chucks, the workover workers can be far away from the wellhead. The completion of the lifting and lowering of the tubing operation, the construction speed is artificially controllable and can reach the level of manual operation, which greatly reduces the labor intensity of the workers, and reduces the various injuries faced by the workers at the wellhead of the station, which is generally welcomed by the workers on the spot.

(4) After the two-person operation of the oil pipe is realized, the original wellhead personnel is trained as the driver, and the vehicle is operated in turn, which can further improve the work efficiency.

(5) After unmanned operation at the wellhead, the manipulator of the workover rig moves more. Therefore, simplifying operations and improving work efficiency through automation and intelligence is the next development direction of this device.

Sanjack has been committed to the research of automatic workover technology for many years and has a perfect automatic workover technology development, production, and manufacturing system.

In recent years, a whole set of automation technology has been formed in the automation and intelligent development of automatic workover equipment. Through the application of module design, servo drive, integrated control, electro-hydraulic compound drive and other technologies, the supporting products suitable for various types of workover equipment have been developed to meet the needs of oilfield workover equipment upgrading.

Drill floor automatic pipe arranging manipulator can replace workers to complete the placement of the column on the drill floor surface, and connect single joint, thread connection, etc., to achieve unmanned operation of the drill floor for major workover operations.

The original integrated structure of hydraulic tong and punching tong can meet the thread up and down of tubing/drill pipe at the same time. The tong head has a floating function, which can automatically compensate the center deviation between the pipe string and the jaw and reduce the damage when the tong teeth clamp the pipe body. The torque can be accurately controlled and set, and the make-up torque of pipe string meets the requirements of API. When in standby, it can rotate and give way as a whole to provide more active operation space for the drill floor. The tong head can be deflected to meet the make-up & break-down of the mouse hole string.

NESR’s fleet of rigs range from 200 HP to 1,500 HP and offer drilling capabilities for all type of wells with depths up to 4000m. Our fleet includes 750 HP truck mounted, fast moving rigs which are ideal for both light and heavy work over campaigns as both rigs are equipped with full edge mud system that can handle normal drilling activities.
