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.

Key words: low permeable reservoir, sandstone reservoir, water injection well, injection rate allocation, sedimentary facies
