High-temperature and high-pressure circulating displacement system

Abstract

The invention discloses a high-temperature and high-pressure circulation displacement system which is composed of an injection system, a high-temperature and high-pressure circulation system, a modelsystem, a back pressure system and a data acquisition and automatic control system. According to the high-temperature and high-pressure circulation displacement system, liquid in a buffer container ispumped into a rock core holder through a double-cylinder constant-speed constant-pressure pump; an annular pressure tracking pump is used for loading tracking annular pressure to an annular cavity ofthe rock core holder, the rock core holder is circularly heated through the heating temperature controller and the annular pressure circulating pump; the temperature requirement of the multifunctional rock core displacement experiment is met; the outlet pressure of the rock core holder is controlled by the back pressure system; data such as experimental temperature and pressure can be acquired and controlled by a computer, the double-cylinder constant-speed constant-pressure pump provides a power source for a test, and the constant-speed constant-pressure pump adopts a digital positioning monitoring servo control circuit, so that a solution can accurately flow under any pressure condition, and the solution can stably flow at a high speed and continuously operate at a constant speed without pulse.
