Abstract

The invention is applicable to the technical field of oilfield exploitation, and provides an intermittent oil pumping unit. The intermittent oil pumping unit comprises an oil pumping unit body connected with an oil well pump; a sensor which is connected to the oil pumping unit body and used for sensing an operation signal of the oil pumping unit body; a brake piece which is connected with the oil pumping unit body and used for controlling the oil pumping unit to be separated; and a controller which is connected with the oil pumping unit body and the brake piece and used for controlling the oil pumping unit body to drive the oil well pump to work for oil pumping, wherein the controller is internally provided with a remote controller; and the remote controller is connected with the sensor, an indicator diagram is generated through a sensing signal of the sensor, the average fullness degree of the oil well pump and the equivalent liquid amount in unit time are calculated, circulating comparison is conducted, and oil pumping operation intermittent control is conducted. The intermittent oil pumping unit has the advantages of being simple in structure, convenient to operate, low in operation cost and convenient to control.

Description

technical field [0001] The invention belongs to the technical field of oil field exploitation, and in particular relates to an interval pumping unit and an interval control method. Background technique [0002] The pumping unit is a large power consumer in the oil production process of the oil field, and during the operation of the pumping unit, especially in the production process of low-permeability, ultra-low permeability, shale oil, tight oil reservoirs and other low-yield and low-efficiency oil fields, due to The operating parameters are seriously mismatched with the downhole fluid production, and the fluid supply capacity of the oil well is far less than the pumping unit's lifting and drainage capacity, which cannot achieve a balance of supply and drainage, resulting in a lot of energy waste. [0003] Currently at home and abroad, manual adjustment of parameters such as the stroke and number of strokes of conventional pumping units and the pump diameter of the pumping ...
