| Abstract: | Based on the reservoir properties and its fluid characteristics in the middle position of Es 3 member in Block Wen 72 of Wennan Oilfield, slime-tube and long core displacement tests are made. The results show that the miscible displacement with hydrocarbon gas injection is carried out in the reservoir as the composition of natural gas reaches to certain demanded proportion and the temperature of injected gases is higher than a critical value, which demonstrates that the gas drive development is feasible and the oil recovery can be enhanced. |
