　　塔里木油田巴什托普井区的主力储层为东河塘组，整体属于低渗透砂岩储层，粘土矿物含量很高。通过岩心敏感性流动实验，对储层的伤害因素及其伤害程度进行了评价。研究表明，该储层高岭石含量低，基本不存在速敏损害；由于粘土矿物的膨胀，致使喉道堵塞，使渗透率下降是引发水敏效应的主要因素；碱敏损害为弱中等偏弱；弱酸敏损害；中等偏弱的应力敏损害。

The major producing layer of Baxtopu oilfield in Tarim is Donghetang formation , which is of low permeability sandstone reservoir, high clay mineral content. The author researches reservoir potential damage factors by the core sensitivity experiment. Results show that the reservoir has few kaolinite and there is no speed sensitivity. The main factor caused the water sensitivity is the permeability decreased, which is due to the expansion of the clay minerals, resulting in throat blockage. The alkali sensitivity extent is from weakness to moderate weakness, the acid sensitivity extent is weakness, stress sensitivity is moderate weakness.
