When the salinity of injected fluid is not compatible with clay minerals in a reservoir, hydrated swell and dispersion of the clay minerals are caused, which makes permeability decreasing.
注入流体矿化度与储层中的粘土矿物不配伍时，会引起粘土矿物水化膨胀和分散，导致渗透率降低。
Swelling, cracking, dispersion, migration and plugging of clay minerals are the main factors of the reservoir damage in high-pressure low-permeability reservoirs.
粘土矿物的膨胀、破裂、分散、运移和堵塞是对高压低渗油藏储层伤害的主要因素之一。
