How to improve the integrated skid of the Oilfield Automatic Workover Rigs to make its operation more efficient?

As oilfield development enters the mid-to-late period, the tasks of workover operations are becoming increasingly heavy. Whether workover operations can be carried out safely and efficiently will directly affect the production and profitability of subsequent oil fields.

The integrated pry block is an important part of the automatic workover rig, which affects the operation efficiency of the oilfield workover, but at the present stage the integrated pry block of the automatic workover rig adopts the forward and backward movement method, during the operation, there are problems such as insufficient working space of the sucker rod and long time-consuming movement, which seriously affects the work efficiency of the workover rig.

The purpose of the utility model is to provide an automatic well workover integrated skid conveying mechanism, which solves the phenomenon of slippage during conveying. In response to this problem, San Jack has developed a new type of integrated pry block. This pry block has a lateral movement function to provide sufficient space for the sucker rod operation, and the movement time is shorter, which solved the problems of traditional workover rigs and improved the efficiency of automated workover operations.

This pry block includes electrical control system, moving mechanism, locking mechanism, hydraulic system, pipe rod conveyor, base, multi-functional wellhead automatic operation device, as shown in the following figure:

At present, the automatic workover integrated skid device is a conventional equipment in workover operations, including electrical control system 1, machine transfer mechanism 2, locking mechanism 3, hydraulic system 4, pipe rod conveyor 5, base 6, multi-functional wellhead The operation device 7, the transfer mechanism 2 is fixed on the base 6, the locking mechanism 3 is set on the transfer mechanism 2, the transfer mechanism 2 is connected to the electrical control system 1 through the hydraulic system 4, and the multifunctional wellhead operation device 7 is also connected to the base. . The automatic well workover integrated skid device also has a conveying mechanism, but the conveying mechanism is driven by the motor to drive the conveying roller to rotate, and there is a slipping phenomenon during conveying.

The present utility model adopts the following technical solutions: an automatic well workover integrated skid conveying mechanism, comprising a conveying roller and a conveying hydraulic cylinder, the conveying roller is arranged on the base of the automatic well workover integrated skid One end of the conveying hydraulic cylinder is connected with the base of the automatic well workover integrated skid block, and the other end is connected with the pipe rod conveyor of the automatic well workover integrated skid block.

Working principle: Take the pry block moving to the left as an example, first control the horizontal cylinders of the two moving mechanisms on the left to extend, then control the four lifting cylinders to extend, the four lifting legs land on the ground, the base is suspended, then control the horizontal cylinders of the two transfer mechanisms on the right to extend, at the same time, the two horizontal cylinders on the left retract, moving the base to a certain distance to the left, then control the four lifting cylinders to retract, the base touches the ground, the four lifting legs are suspended, finally control the two translation cylinders on the right to retract to complete a left movement cycle In this way, through multiple cycles of movement, the pry block can be moved to the left.

A conveying mechanism is added on the base, and the conveying mechanism includes conveying rollers and conveying hydraulic cylinders. The conveying rollers are located on the base and are evenly distributed in multiple groups. One end of the conveying hydraulic cylinder is connected to the base and the other end is connected to the pipe rod conveyor. The conveying hydraulic cylinder drives the pipe rod conveyor to extend or retract. The movement of the pipe rod conveyor is realized, which effectively avoids the phenomenon of slippage during the movement.

The shifting mechanism of this pry block is fixed at the front and rear ends of the base, and the horizontal moving direction is perpendicular to the length direction of the base, thereby realizing the lateral moving function of the pry block. Through this improvement, the automatic workover rig can carry out workover operation more efficiently.
