Embodiment Construction

[0011] The present invention will be further described below in conjunction with drawings and embodiments.

[0012] Such as figure 1 , the new diaphragm hydraulic oil well pump belongs to positive displacement pump, and its mechanism of action is as follows.

[0013] (1) The power fluid is injected into the downhole pump body from the power pipe through the control system placed on the ground, so that the power fluid fills each group of rubber bladders in the pump body, and the rubber bladders gradually expand. At the same time, the disc spring deforms. The inflated rubber bladder will compress the crude oil in the driving chamber of the pump body, so that the crude oil is discharged through the upper discharge valve. At the same time, the lower suction valve is closed, and the upper discharge valve is opened, and then the crude oil is lifted to the surface system.

[0014] (2) Release the pressure of the power fluid through the ground control system, and at this time, the d...

Abstract

A control system of a diaphragm hydraulic oil pump is composed of a hydraulic control module, a data collection and processing module, and a monitoring and alarming module to realize automatic control and real-time monitoring of the working state of the downhole pump body. The control system is made by comprehensively considering the working characteristics and control requirements of the oil well pump. Based on the above analysis, comprehensive debugging of the system, switching the time interval through the control system, and reducing the stagnation time as much as possible can effectively increase the "stroke frequency", thereby increasing the liquid production of the deep well pump system. The system has a simple structure and high reliability. , fully adapt to the site environment, have strong anti-interference ability and low cost.

Description

Technical field [0001] The invention relates to a control system of a diaphragm type hydraulic oil pump, which is suitable for the mechanical field. Background technique [0002] Remote oil drainage is an important process in downhole operations. In the oil testing operation, in order to understand the liquid production properties and production capacity of the oil layer, it is necessary to adopt the method of manual lifting to discharge a certain amount of liquid from the oil well. The solution to this problem is called oil testing and drainage. At present, the hydraulic rodless pump commonly used in the drainage process generally adopts the plunger type, which has the disadvantages of high energy consumption and mixed discharge of power fluid and formation fluid. The author mainly studies the design scheme of the diaphragm hydraulic pump control system. Contents of the invention [0003] The invention proposes a control system of a diaphragm hydraulic oil well pump, wh...
