Abstract

The invention discloses an intelligent oil pumping system, which comprises an oil pumping unit, an oil pumping pump and a PLC (Programmable Logic Controller) electronic-control system, wherein the oil pumping unit comprises a rack; the rack is provided with a speed reducer, one input end of the speed reducer is connected with an automatic-operation motor by a coupler, and the side surface of the coupler is provided with a proximity switch; the other input end of the speed reducer is connected with a manual operation motor by a dead-electricity brake clutch and a roller chain; two output ends of the speed reducer are provided with two winding drums with opposite rope race rotation directions; a steel wire rope A and a steel wire rope B respectively pass by pulleys of the beam hanger and a balance weight; then the steel wire rope A and the steel wire rope B are respectively fixed at inner ends and outer ends of the two winding drums by rope clips; and an oil rod and a plunger connected with the beam hanger are arranged in the oil tube and a pump barrel. The intelligent oil pumping system is characterized in that the upper end of the pump barrel is connected with the inner tube; the lower end of the pump barrel is connected with a low-resistance fixing valve; an oil reservoir is arranged outside the inner tube, the pump barrel and the low-resistance fixing valve; an outer tube is connected with the fixing valve in a sealing mode to form an oil pumping path together with the fixing valve; and oil in the oil reservoir opens the low-resistance fixing valve under the action of hydraulic column pressure and enters the pump barrel.

Description

technical field [0001] The invention relates to an oil pumping equipment developed in an oil field, in particular to a high-efficiency intelligent oil pumping equipment. Background technique [0002] There are hundreds of thousands of oil wells in my country, and rod pumping wells account for more than 95%, and more than 95% of rod pumping equipment are beam pumping units imported from abroad. Rod pumping wells in foreign countries are also dominated by beam pumping units, but the difference between domestic and foreign oil fields lies in the different national conditions. First of all, the main characteristics of my country's oil reservoirs are low permeability and low reserves per unit area, resulting in a situation of numerous wells and low single-well production; secondly, my country's rapid economic development, urgent demand for energy, high production intensity of oil wells, and production stimulation measures The workload is heavy, resulting in poor well conditions a...
