Description

Technical Field

[0001] The utility model belongs to the technical field of oilfield production tool maintenance, and relates to a plunger pump maintenance tool, in particular to a maintenance tool for profile control, drive control and water plugging injection devices in the oilfield production field. Background Art

[0002] As most of my country's oil fields have entered the high or ultra-high water-cut development period, inefficient or ineffective circulation of injected water is a common problem restricting the development of oil fields. Profile adjustment and flooding control technology is an important means to control water and stabilize oil and improve the water injection sweep coefficient in the high water-cut stage of heterogeneous reservoirs in the middle and late stages of oil field development.

[0003] However, due to the long construction period and heavy workload of profile control and drive control, three-plunger or five-plunger drive control pumps are prone to problems such as air intake or failure to supply liquid during long-term operation, requiring the pump to be stopped for maintenance. However, traditional hardware tools are not compatible or inconvenient to operate.

[0004] Since the plunger pump is always in a state of continuous high-speed operation, the hydraulic end of the plunger pump is particularly prone to damage, such as valve breakage, valve seat wear, spring breakage, component jamming, etc. The working condition of the hydraulic end of the plunger pump plays a decisive role in the safe operation of the plunger pump, and also indirectly affects the quality of injection polymerization. Strengthening the daily maintenance of the plunger pump is an effective measure to improve its performance, and is also an important part of injection polymerization production.

[0005] The maintenance tools we currently use on site are made of poor quality and are easily damaged. During operation, the labor intensity of employees is high, and improper use of tools can easily cause harm to personnel. At the same time, maintenance time is prolonged, work efficiency is low, and it cannot meet current production requirements.

[0006] CN 206416129 U discloses a new type of plunger pump hydraulic end repair tool, including: a body, a screw hole, a handle, an anti-slip ball head, a collision sleeve, a connector, an eccentric wheel, a positioning boss, a fixing hole, and a positioning hole; the body of the new type of plunger pump hydraulic end repair tool is a rod-type structure, a non-slip handle is provided at the left end of the body, a spherical anti-slip ball head is provided at the left end of the handle, a curved circular tubular collision sleeve is worn on the rod body of the body, a screw hole is provided at the right end of the body, and the screw hole is connected to a threaded rod provided at the left end of the connector; the connector is a step-shaped rod-type structure, the left end of the connector is a threaded rod, and the right end has a "U"-shaped groove along the axis, and the "U"-shaped groove is provided with fixing holes with the same axis and the same diameter above and below, and a pin passes through the fixing hole and the positioning hole to position the eccentric wheel in the "U"-shaped groove. However, its structure is relatively complicated and not easy to clean.

[0007] In view of the above problems, there is an urgent need to design a maintenance tool specifically for the plunger pump to reduce the labor intensity of workers, improve work efficiency, and avoid equipment damage caused by tool mismatch or improper operation. Summary of the invention

[0008] The utility model aims to provide a plunger pump maintenance tool used in the processes of profile control, drive control and water plugging.

A fixed block is welded on the action rod, and the action rod is covered with a top block and a straightening block, and the top block and the straightening block are welded together as a whole. The handle is used to facilitate operation when installing or removing the plunger pump ball seat and valve. The function of the fixed block, top block and straightening block is to use the top block welded with the straightening block to hit the fixed block when the plunger pump ball seat and valve are removed, so as to remove the plunger pump ball seat and valve.

[0012] During maintenance, determine the appropriate hexagon socket screw based on the hole size of the plunger pump ball seat.

[0013] Preferably, the length of the handle is 1.5-3 cm.

[0014] Preferably, the length of the actuating rod is 1-1.5 cm.
