防止油层伤害最基本的方法是做入井流体与油层、原油、油层水配伍性实验，避免油层发生不期望的变化。

In order to avoid change without expectation. we should do some compatibility experiments about well fluid , the oil layer, the crude oil and the oil layer water.

驱油试验时，对其发泡能力、稳定性与地层水的配伍性及耐油性进行了评价。

Its foaming capacity, stability, compatibility with formation water and oil resistance are evaluated in oil displacement test.

实验表明：两种聚合物体系的各种处理剂与地层水的配伍性好，储层岩心的动态渗透率恢复值在80%以上。

Tests results showed these two fluids have good compatibility with formation fluids, and the dynamic permeability recovery of reservoir rock was more than 80%.
