Embodiment

[0025] Such as figure 1 As shown, the oil well pump detection and repair process involved in this embodiment includes the following steps:

[0026] (a) recycling old oil well pumps;

[0027] (b) Disassemble and test the recovered old oil well pump;

[0028] (c) followed by cleaning;

[0029] (d) further testing after cleaning;

[0030] (e) Repair the oil drain;

[0031] (f) optional plunger;

[0032] (g) Assembling the well pump;

[0033] (h) detection flexibility, measurement leakage;

[0034] (i) tightness inspection;

[0035] (j) Fill in the maintenance records;

[0036] (k) Identification, ready for use.

[0037] In the step (b), the detected problems are described and recorded.

[0038] In the step (d), the detection includes: the detection of the inner and outer walls of the pump barrel, the detection of the plunger, the detection of the fixed Vers and the detection of the moving Vers.

Abstract

The invention discloses a detection and repair technique of a defueling pump. The detection and repair technique comprises the steps: (a) recycling an old defueling pump; (b) dismantling and detecting the recycled old defueling pump; (c) cleaning; (d) carrying out further detection after cleaning is finished; (e) repairing a drip; (f) selecting and matching a plunger; and (g) assembling the defueling pump. According to the detection and the repair technique of the defueling pump, the detection and repair on the defueling pump can be completed successfully, so that the purpose of reusing wastes is achieved, production cost is reduced, and the purposes of energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to a technique for detecting and repairing an oil well pump. Background technique [0002] In crude oil production at home and abroad, mechanical oil recovery occupies the primary position, and in mechanical oil recovery, oil well pumps are the main ones. Oil well pump is one of the most basic, reliable and widely used oil pumping tools. According to statistics, the oil pump accounts for more than 90% of the mechanical oil production wells. The oil pump equipment plays a vital role in the entire crude oil production. The economic loss caused by the failure of the oil pumping device, especially the downhole device is extremely huge. Therefore, timely and accurate monitoring and judgment of the working status of the oil pump, and effective and timely processing of the failures that occur will not only greatly reduce the production cost of crude oil and obtain higher economic benefits, but will also help to further improve the oil ...
