Abstract

The invention discloses a pumping unit jig frequency, balance real-time capacity adjusting method and a device of the pumping unit jig frequency, balance real-time capacity adjusting method, and belongs to the field of oilfield digital construction and management. A traditional parameter adjustment method is changed, the problems of parameter adjustment hysteretic quality, high staff labor intensity and incapable expression of oilfield potential to the largest extent are solved, and oilfield production efficiency and oilfield digital management level are improved. Due to the fact that pumping unit working conditions are analyzed in real time and a parameter is intelligently adjusted according to measured real-time data, a pumping unit can operate under a reasonable working system, the oilfield potential is expressed to the largest extent, and delicacy management of an oilfield is achieved. Due to the fact that indicator diagram data and electric parameter data are collected in real time and rotating speed of a motor is controlled through a digital pumping unit integrated control device according to system efficiency optimized jig frequency, and stepless jig frequency is adjusted. Balance degree is calculated through current and power obtained in real time, balance of the pumping unit is adjusted through a screw balance adjustment device, and therefore the balance of the pumping unit is adjusted, the pumping unit keeps operating under an optimized production parameter, and the oilfield potential is expressed to the largest extent.

Description

technical field [0001] The invention relates to the field of digital construction and management of oil fields, in particular to a method and device for real-time intelligent adjustment of stroke times and balance of a pumping unit. Background technique [0002] Pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine", which makes oil out of the well by pressurizing. Among them, "stroke times" refers to the number of times the sucker rod reciprocates up and down per minute in the pumping well. [0003] The traditional method of adjusting stroke times and balance of pumping units is carried out in the following steps: first, employees are required to go to the site to measure the power diagram and current of the oil well; Check whether the pumping unit is balanced; then adjust the stroke times by replacing the pulley, and adjust the balance of the pumping unit by increasing or decreasing the balance block. [0004] Limited by ...
