Fractured reservoir body water-oil displacement simulation system equipment with good heat insulation property

Abstract

The invention discloses fractured reservoir body water-oil displacement simulation system equipment with good heat insulation property. The fractured reservoir body water-oil displacement simulation system equipment comprises a constant-speed constant-pressure pump, the constant-speed constant-pressure pump is arranged outside an intermediate container, a pressure transmitter is fixedly mounted on one side of the intermediate container, the pressure transmitter is fixedly mounted on the upper surface of a pressure cabin, a buffer container is arranged outside the pressure cabin, a pressure gauge is fixedly mounted at the top of the buffer container, a back-pressure valve is fixedly mounted at the top of the buffer container, and a metering pipe is fixedly mounted on one side of the back-pressure valve. According to the fractured reservoir body water-oil displacement simulation system equipment with the good heat insulation property, by arranging the constant-speed and constant-pressure pump, continuous pulse-free constant-speed and constant-pressure operation can be achieved, pressure protection and position upper and lower limit protection are achieved, the functions of suction, liquid drainage and pre-pressurization are achieved, an electromagnetic control pneumatic valve is adopted as a reversing valve, the volume of a pump cavity is small, the standing time is short, the pump is provided with a communication port and can be operated by a computer or manually, and the whole device is simple in structure, easy to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of petroleum and natural gas exploitation, in particular to a water flooding oil simulation system device for fracture reservoirs with good thermal insulation. Background technique [0002] The water flooding oil simulation device is used to simulate the oil recovery operation of injecting water into the oil field to displace the crude oil. Before the actual oil recovery operation, the effect of the production plan to be implemented can be predicted and evaluated by implementing the water flooding experiment. [0003] The water flooding oil simulation device in the related art includes an advection pump and a rock core. During the experiment, water was driven by the advection pump to displace the simulated oil saturated in the core. [0004] There are following defects or problems in the prior art: [0005] 1. The existing computer support board for office computer workers to prevent cervical spondylosis ...
