This paper investigated the water sensitive and velocity sensitive damage in Anan oilfield, and formation damage caused by poor water quality injected.
讨论了阿南油田注入水的水敏性和速敏性损害以及由于注入水水质不合格带来的储层损害。
Experiment shows that the reservoirs in Yanchang formation of Ordos Basin are stress-sensitive to different extent, resulting in damages of different degree to reservoir oil/water percolation.
室内实验发现，鄂尔多斯盆地延长组储层存在不同程度的应力敏感，由于应力敏感，对储层的油水渗流伤害程度也存在一定的差别，且油的渗流伤害普遍大于水的渗流伤害。
