一、Overview

The device simulates the reservoir pressure and temperature,with the aid of the latest achievements of modern science and technology to carry out kinds of simulated experiments based on the displacement mechanism and analog mechanism.It can be used to do the reservoir sensitivity,damage evaluation,gas drive,foam drive and the physical simulation of chemical flooding and dynamic displacement comprehensive evaluation;It can research the influence of porous medium to the simulated oil displacement system’s percolation(liquid permeability,oil-water relative permeability,basic water injection experiment)and oil displacement efficiency.It can carry out the production technology research, such as fracturing,acidification, water shutoff, adjustment of injection-production profile experiment.It is used to carry out the experimental research such as the miscible/immiscible displacement efficiency evaluation which is related to gas drive development technology,the seepage characteristics in the process of oil displacement by gas,as well as the optimization of gas injection methods and so on.
