注水水质对低渗透储层损害实验研究

摘要

注水水质的好坏直接影响到低渗透区块的吸水能力和驱油效率.本文在只考虑悬浮物的含量、粒径及含油量的情况下,通过岩心流动实验,对岩心渗透率的损害程度进行了一定的实验研究发现其对岩心渗透率有一定的损害.因此,必须对注水水质进行严格控制.%The quality of water injected exert influence on the injectivity and displacement efficiency of a low permeability reservoir. Given the content,diameter and oil content of suspended substance,the researches are carried out by means of core flow experiments to prove that qualityof water injected do damage on core permeability. Therefore the quality of water injected need to be controlled strictly.
