Embodiment Construction

[0031] The embodiment of the sucker rod hanger 12: take the sucker rod hanger 12 with the outer diameter of the suspension body 3 as 47mm, the upper internal thread screw thread 2 as 25.4mm, and the lower internal thread sucker rod buckle 4 as 22.2mm as an example , the present invention will be described in further detail.

[0032] refer to figure 1 . The sucker rod hanger 12 of the present invention is composed of a base plate 1 and a suspension body 3 . The suspension body 3 is cylindrical, with an outer diameter of 47mm and a length of 240mm. The suspension body 3 has a central hole. The upper end of the center hole has an internal screw thread 2 with a specification of 25.4mm, which can be connected to a 25.4mm sucker rod nipple. The lower end of the center hole has an internal thread sucker rod buckle 4, and the specification is 22.2mm, which can be connected to a 22.2mm sucker rod.

[0033] refer to image 3 . There is a symmetrical plane 5 on the outer wall of ...

Abstract

A pressure testing operation method with a rod for an oil well is applied to the technical field of pressure testing operation for repairing a well for an oil field. The method is characterized in that; at first, the construction operation of arranging an oil piping string is accomplished; the construction operations of arranging an oil pump and an oil pumping rod of next step are carried out ahead of time; when a pump track arrives a scene, the construction operations of arranging the oil pump and the oil pumping rod are stopped; the upper end of the oil pumping rod arranged in the well is connected at the lower end of the suspender of the oil pumping rod; a pressure testing pump track and a pressure testing pipe line are connected to carry out the pressure testing operation of an oil pipe and accomplish the pressure testing operation; the upper part of the suspender of the oil pumping rod is connected with the short joint of the oil pumping rod; the short joint of the oil pumping rod and the suspender of the oil pumping rod are upwards picked up and then the suspender of the oil pumping rod is dismounted; the rest construction operation for arranging the oil pumping rod is continuously finished until the operation of arranging the oil pumping rod is finished. The pressure testing operation method with a rod has the effects that: the lower side of the suspender of the oil pumping rod can suspend the oil pumping rod and can be sealed on the suspender of the oil pipe at the opening of the well; the oil pumping rod can be arranged continuously after the oil pipe is arranged; the construction progress and the pressure testing operation on the oil pipe can not be affected.

Description

technical field [0001] The invention belongs to the technical field of oil field workover operations, in particular to the pressure test process of oil wells, and is a pressure test process for pump trucks as they arrive. Background technique [0002] During the workover operation of the oil well, the tubing string should be lowered first, and then the pressure test operation should be carried out after the tubing string is completed; After that, normal oil recovery work can begin. The order cannot be reversed. [0003] When it is necessary to carry out the pressure test operation after the tubing string has been lowered, the pump truck, the main equipment for the pressure test operation, cannot arrive at the site in time, and the pressure test operation cannot be carried out, resulting in a shutdown and waiting, and it is impossible to complete the subsequent work of lowering the oil well pump and sucker rod . Not only will it affect the progress of pressure test constru...
