Abstract

The invention provides a submersible motor reciprocating pump and an intelligent decision-making method based on self-sensing. It includes an intelligent control cabinet, a plunger type oil well pump and an oil submersible linear motor, and is characterized in that it also includes a wellhead data acquisition unit and a downhole data acquisition unit, and the intelligent control cabinet is electrically connected to the oil submersible linear motor through an armored cable ; The downhole data acquisition unit is signal-connected to the intelligent control cabinet through the armored cable carrier, and the wellhead data acquisition unit is signal-connected to the intelligent control cabinet. Integrating downhole sensing data acquisition technology, it can sense and measure the state of downhole oil fluid and the operating parameters of the equipment itself, and intelligently adjust the operating parameters of the equipment according to the measured parameters. The shortcomings of making corresponding adjustments in a timely and accurate manner.

Description

technical field [0001] The invention belongs to the field of oil well production, and relates to a submersible motor reciprocating pump and an intelligent decision-making method based on self-sensing. Background technique [0002] Global oil reserves are decreasing day by day, but oil consumption is increasing day by day. Petroleum, a non-renewable resource, is one of the main energy sources in modern society. How to rationally exploit oil, effectively utilize oil, and improve oil recovery efficiency has become a widespread concern. In order to improve the efficiency of oil production equipment, the commonly used improvement method at home and abroad is to use downhole rodless oil production equipment, such as submersible centrifugal pumps, submersible screw pumps, etc. to replace conventional rod-type oil production equipment, such as beam pumping units , surface screw pump, etc., simplify the intermediate transmission link and improve oil recovery efficiency. However, the...
