Problems solved by technology

But the CO of this method 2 The concentration distribution is obtained by pure calculation. The calculation of parameters such as equation of state, compression factor, and expansion coefficient in the mathematical model may have a large error with the real state of the reservoir, thus affecting the CO2 in crude oil. 2 Concentration Final Results
[0004] It can be seen that the various methods currently used for the dynamic analysis of gas drive reservoirs still have many limitations, and there is no evaluation method and evaluation system that can accurately measure the mass transfer and dissolution of the oil-gas interface in real time.

Description

technical field [0001] The invention belongs to the technical field of gas drive oil recovery, and relates to a visible temperature and pressure resistant device, a gas-liquid interface mass transfer and dissolution measurement device and a method. Background technique [0002] At present, for reservoirs developed by natural gas top-driven energy or artificial gas injection flooding, when the breakthrough of the gas flooding front occurs, the oil-gas two-phase seepage law in the gas flooded reservoir will become very complicated, and this will also give gas Efficient development of flooded reservoirs presents a number of challenges. In order to improve the overall development effect of the reservoir in the gas drive production stage, it is necessary to predict and evaluate the production performance and development effect of the reservoir. However, for gas drive reservoirs, the production performance prediction generally adopts reservoir numerical simulation method. Calcula...
