250hp workover rig 350hp workover rig Oilfield Automatic Workover Rig
Oil well w orkover is a high-tech, high-risk work. The c onventional oilfield workover rig has problems such complicat ed operat ing procedures and high labor intensity. Shengji, in cooperation with the 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 need s 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, reduc e s the number of operators, decrease s workers' labor intensi ty. The technolog y is advanced, safe and reliable.
1. Designed with a drilling company, first of its kind.
2. One-button automated operation with high degree of automation.
3. Reduc e s labor cost.
4. Decreases labor intensity.
5. Operation is safe and reliable.
