The invention relates to a mechanical oil recovery testing platform which is used for the oil recovery of an oil field and can simulate the working condition and the working action of a mechanical oil recovery system. The mechanical oil recovery testing platform comprises three parts which are an experimental platform rack, a fluid supply and discharge system and a measurement and control system, wherein the experimental platform rack mainly comprises an oil pumping unit, a pitshaft platform rack, a pitshaft assembly, a sucker rod, a stroke loss simulator, a bracket and the like; the fluid supply and discharge system mainly comprises a liquid storage tank, a liquid supply pump, a frequency converter of a reciprocating pump, an air supply pump, an air storage tank, a gas-liquid separator, a pitshaft fluid input pipeline, an oil pumping pump, a liquid overflow pipeline and the like; and the measurement and control system comprises a control box of the oil pumping unit, a liquid flowmeter, a gas flowmeter, a temperature transmitter, a pressure transmitter, a frequency converter of a reciprocating pump and the like. The invention can realize the simulation of the working condition of the gas-liquid two-phase liquid supply and discharge of an oil pumping system and the simulation of the working action of a mechanical oil recovery system and provides a very good experimental technical means for the research of the structure and the performance of mechanical oil recovery equipment.

Description

technical field [0001] The invention relates to a mechanical oil recovery test platform for oil recovery in an oil field, which can simulate the working condition and working behavior of the mechanical oil recovery system and is used for the experimental research of the mechanical oil recovery system. technical background [0002] Mechanical oil recovery is the main method of oil recovery in oil fields, accounting for more than 90% of oil production wells in oil fields. Improving the efficiency and reliability of mechanical oil recovery systems plays an extremely important role in improving the economic efficiency and management level of oil field production. However, the structure of the mechanical oil production system is complex, and there are many factors affecting its work efficiency. In order to ensure the safe and efficient operation of the mechanical system on site, on the one hand, it is necessary to develop or improve the mechanical pumping equipment with high effic...

Problems solved by technology

Obviously, the mechanical oil extraction equipment developed or improved in this way can not only guarantee the safe and efficient operation of individual equipment, but also cannot guarantee the safe and efficient operation of the system

[0003]At present, there are only mechanical oil recovery test platforms with simple structure and single function in China

Because the existing mechanical oil recovery test platform does not have the real simulation of the pumping system movement law, the real simulation of the gas-liquid two-phase f
