Product description
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 system includes double monkey board pipes ranging robot, bolted beam system, machine hand, power catwalk, power elevator, hydraulic chuck, power control and monitoring system. The system uses one-button automated operation. The operation only needs one driller, one wellhead operator and one patrol personnel.
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 rig structure is compact and well designed, highly integrated, and optimized to save working space. The power system is a hydraulic+ mechanical type with high comprehensive efficiency. A class II or self-propelled type chassis can be adopted to meet the various requirements of the end-users. The mast is front-open type, with a single section or double-section structure, hydraulic raising and hydraulic telescoping, or mechanical telescoping. Band brake or hydraulic disc brake can be applied as the main brake of the drawworks. The water cooling thrust plate pneumatic brake or water brake can be used as an auxiliary brake. The drill floor is a twin-body telescopic type or a parallelogram structure, both of which are convenient for installation and transportation. The dimension and height of the drill floor can be designed according to the end-user's requirements.
