| 摘 要： | 英南2井在完井试油和酸化改造后储层受到了严重伤害，产量明显降低，通过实验手段，对造成伤害的原因进行了分析。认为造成该井储层伤害的主要原因是水锁造成的伤害，其次水敏，酸敏以及酸化过程中的二次沉淀也具有一定的伤害。要解决该类储层的伤害问题，可采用油基钻井液施工。

| Abstract: | Reservoir is seriously damaged in well Yingnan-2 after completing test and acidization,and production is obviously reduced.Through experimental analysis,the main reasons of reservoir damage caused are water lock,water sensitivity,acid sensitivity and secondary precipitation during aciding.Meanwhile,the paper proposes that using oil-base drilling fluid can prevent the reservoir damage. |

| Keywords: | reservoir damage measure water lock water sensitivity aciding oil-base drilling fluid |
