Background
Top gas injection gravity assisted steady flooding is considered one of the most promising methods for effectively increasing the recovery of such reservoirs, the highest of all immiscible flooding, even twice that of water flooding. Because the density difference exists between the injected gas and the crude oil, the gas with lower density can be separated from the crude oil with higher density by controlling reasonable oil extraction speed and utilizing gravity stabilization, so that the gas fingering is inhibited when fingers are going to be formed, and the defects of low displacement efficiency, easy gas channeling and the like caused by gas viscous fingering and gravity override action in the horizontal gas injection displacement process are avoided. In addition, since the 60 s in the 20 th century, many countries in the world including the United states, Russia and the like have developed the research on the air injection technology of light oil reservoirs, and many deep light oil reservoirs have developed the air injection field test and have both technical and economic success; although the low-temperature oxidation exploitation of the light oil reservoir is late in China, the low-temperature oxidation exploitation of the light oil reservoir is widely concerned in recent years due to wide air sources and low cost, and the combination of top gas injection and air flooding can better exert the characteristics of high efficiency and economy.
The exploitation of the light oil reservoir by injecting air has the defect of unsafe factors, namely, hydrocarbon gas and oxygen in the produced gas are mixed and easily explode when the injected air and crude oil are not completely subjected to low-temperature oxidation reaction; the gas channeling is easily caused by unreasonable injection and production parameters, so that relevant indoor experimental research is strictly required to be made in the early stage, and the injection and production parameters are reasonably optimized on the basis. This presents a new challenge window for top air injection gravity assisted flooding experimental methods and devices.
The prior art develops a large amount of work in the aspects of simulation methods and devices for low-temperature oxidation dynamic evaluation experiments in air injection development of light oil reservoirs, but the prior art still has the following defects:
1) the dip angle of the formation cannot be simulated and does not represent the real formation conditions.
2) Dead oil is used in the experimental process and cannot represent the actual oxidation characteristics of crude oil in the stratum.
3) The model pipe is horizontally arranged, the adjustment of the model pipe to the stratum inclination angle is difficult, the model pipe cannot represent the real stratum condition, the gas channeling is easy to generate, and the reliability of the time result is reduced.
4) The device is not designed for air injection and therefore does not take into account the safety issues of the produced mixture.
