摘要(Abstract)：
通过萨北开发区断层区油水井在开发过程中所表现出的特性 ,从动态角度出发 ,根据断层两侧油水井连通情况、生产形势变化和投注聚合物后的一些情况 ,结合静态及构造资料 ,对萨北开发区75、 76、 78号断层的封闭性进行了重新认识。分析认为 75、 76、 78号断层具有一定的开启性 ,但因为没有产生油井液量猛升或暴性水淹 ,所以断层的开启性仅是局部的。并对断层区提高油水井水驱控制程度和挖掘潜力作了初步探讨
The enclosed characteristics of Faults No 75, No 76 and No 78 in Sabei development area is dynamically recognized based on the features of producers and injectors in the fault area of Sabei development area during development .The recognition is done according to the communication conditions of producers and injectors on both side of the fault, the change of production, the change after the injection of polymer, and static and structural data. It is believed in this paper that Faults No 75, No 76, and No 78 have certain opening ability. The opening ability of the fault is regional because there is not the rough increase of liquid volume in producers or sudden water inflax. In this paper there are also discussions about improving the swept volume of water flooding and tapping potentialities.
