| 摘 要： | 合理的配注原则、提高水驱油效率是高含水期油田开发的重要工作之一。根据不同沉积相带的储层物性的不同,建立了不同的注水井配注原则,特别是对低渗透储层,首次提出应用最佳驱替速度,建立合理驱替压差来配注的原则,在实际应用中取得了比较好的效果,为低渗透砂岩油藏“调水增油”提供了技术保障。

| Abstract: | It is an important task to allocate water injection rate reasonably for the purpose of improving the efficiency of water flooding. According to the reservoir properties of different sedimentary facies, a set of water injection rules were worked out. In low permeable reservoir, especially, the rate allocation rule of water injection was put forward on the basis of he reasonable pressure difference in terms of optimal water flooding velocity, which was proved practical in real field test. The water injection rules presented in this paper laid a technical basis for enhancing oil recovery by adjusting water injection rate in low permeable sandstone reservoir. |
