Device and method for controlling fixed-point start and stop of intelligent intermittent oil pumping unit

Abstract

The invention discloses an intelligent intermittent pumping unit fixed-point start-stop control device and method. The intelligent intermittent pumping unit fixed-point start-stop control device comprises a workbench, a supporting table is arranged on the upper side of the workbench, a walking beam is rotationally connected to the upper end of the supporting table, a horse head is arranged at one end of the walking beam, a lower stop mechanism is arranged at one end of the workbench, and a driving mechanism is arranged on the upper side of the workbench. The remote end of the workbench is provided with the intelligent fixed-point intermittent opening control cabinet, the intelligent fixed-point intermittent opening control cabinet can remotely and automatically start and stop through a network, then intermittent opening operation is completed, meanwhile, an automatic program is set in the intelligent fixed-point intermittent opening control cabinet, personnel do not need to conduct field manual operation, the labor intensity of operators is reduced, and the working efficiency is improved. And meanwhile, the method is not influenced by the proficiency of operators, can adapt to different use scenes and operation time, and is high in operation precision.

Description

technical field [0001] The invention relates to the technical field of pumping units, in particular to a fixed-point start-stop control device and control method for an intelligent interval-opening pumping unit. Background technique [0002] my country's ultra-low permeability oilfield reserves are relatively rich in resources. In recent years, the proportion of low-permeability reserves in my country's proven petroleum geological reserves accounts for 60-70%. It is of great significance to study, explore and summarize the development technology of ultra-low permeability oilfields. In recent years, most of my country's oil fields have entered the late stage of development one after another. The difficulty of mining old oil fields has been increasing. Some oil field blocks are in low-efficiency and ineffective development. Oil wells have low production and high production costs. Some wells have intermittent oil and fluid supply. Insufficient such "dry pumping" inefficiencies, t...

Problems solved by technology

[0005] The purpose of the present invention is to solve the traditional start-stop method, the error rate of manual start-stop is high, and the frequent start-stop increases the labor intensity, and the start-stop time is inaccurate due to manual influence, and at the same time, it cannot automatically brake when starting and stopping. , so that there are potential safety hazards during the willing operation, and an intelligent intermittent pumping unit fixed-point start-stop control device and control method are proposed
