Intelligent non-beam hydraulic oil pumping technology and hydraulic oil pumping machine

Abstract

The invention relates to an intelligent non-beam hydraulic oil pumping technology and a hydraulic oil pumping machine, and belongs to the technical field of oil and gas field extraction equipment.According to the technical scheme, the hydraulic oil pumping machine is composed of a main engine, a hydraulic station and an intelligent electrical control system; gravitational potential energy of a down stroke and an output of a hydraulic motor are stored through a two-way energy-saving distributor and are released in an up stroke to reduce energy consumption; loading force generated in the working process and strokes are measured by sensors and transmitted to the intelligent electrical control system; the measured loading force and strokes are processed through a data analysis processor and stored in an indicating diagram mode; an indicating diagram in the real-time working process is analyzed and compared with a fault indicating diagram prestored in the system, and effective data analysis and alarm indication are provided.The intelligent non-beam hydraulic oil pumping technology and the hydraulic oil pumping machine have the advantages of being long in stroke, low in stroke frequency, large in load and the like, adjustment is convenient, the size is small, the economic benefit is high, self-adaptive adjustment of the stroke frequency is achieved, and the efficiency of the hydraulic motor is improved.

Description

technical field [0001] The invention relates to an intelligent beamless hydraulic pumping process and a hydraulic pumping unit, belonging to the technical field of oil and gas field pumping equipment. Background technique [0002] At present, most oilfields in my country are in the middle and late stages of development, and the types of developed reservoirs are becoming more and more complex. The proportion of heavy oil wells and high water content oil wells is increasing. To improve the production and production efficiency of heavy oil wells, pumping units with long strokes and low strokes are required. , Large load characteristics. The traditional beam pumping unit in the background technology is relatively mature, but due to the structural characteristics of the beam pumping unit itself, it is still difficult to realize the above functions; the main problems in the background technology are as follows: The pumping unit is heavy, occupies a large area, and has a large civi...

Problems solved by technology

The traditional beam pumping unit in the background technology is relatively mature, but due to the structural characteristics of the beam pumping unit itself, it is still difficult to realize the above functions; the main problems in the background technology are as follows: The pumping unit is heavy, occupies a large area, and has a large civil foundation; the installation, adjustment, and maintenance of the equipment are cumbersome, and the process is cumbersome, requiring a lot of manpower and material resources; Therefore, safety problems are likely to occur during installation, operation and maintenance; stroke and stroke times adjustment is troublesome; since the beam pumping unit requires a large starting torque, the installed power is large, and there are problems with large horses and small carts; Always check the balance rate and adjust it so that the balance rate is between 85% and 115%, otherwise the equipment will vibrate and consume power; special detection instruments need to be installed to measure the indicator diagram; centralized monitoring cannot be realized
