通过模拟试验,在低渗透率和中高渗透率的岩样中,研究了注入水中的固相颗粒对岩样渗透率损害率的影响.结果表明,注入水中的固相颗粒直径和含量增加,岩样渗透率损害率增加;注入水中的固相颗粒对低渗透率岩样的损害大于中高渗透率岩样;注水量增加,岩样渗透率损害率增加;对油田注水控制固相颗粒具有重要的意义.

Through a simulating experiment the rock permeability damage was studied, which was caused by the solid particles from water injection in the rocks with different permeability. The result of study shows that the diameter, content of solid particles and the water injection rate increase with different permeability, the damage rate of permeability increase, and it is important for choosing appropriate solid particles in the oilfield.
