在每级评价中建立断层封堵性评价的临界封堵界限，可实现对于断层封堵性关键因素的评价。

Critical sealing threshold in each evaluation stage was established for evaluation on the fault sealing property, which may evaluate the key factors of the fault sealing property.

根据邻井对比、储层预测及断层封堵性研究，认为清22北断层及大洼断层都是封堵的，因此圈闭是有效的。

According to offset Wells correlation, reservoir prediction and fault seal study, it was considered that the northern fault and Dawa fault of Qing 22 was sealed, so the prospect is effective.
