张强凹陷北部地区位于张强凹陷前辛背斜带北部,受多次构造运动的影响,断层发育,构造复杂。义县组地层录井显示好,储层物性好,已有3口探井出油,但后续开发井即使位置高也不出油,因此利用录井、测井、试油资料,对该区义县组储层进行详尽的分析,对义县组地层的含油潜力做出正确的评价。
The northern part of Zhangqiang Depression is located in the northern part of the former anticlinal zone of Zhangqiang Depression. Due to the multiple tectonic movements, the faults are developed and the structures are complex. The well logs of Yixian Formation show well and the reservoir properties are good. There are 3 exploration wells out of oil, but follow-up development wells do not have oil even if the positions are high. Therefore, by using logging, well logging and oil testing data, County reservoir analysis of a detailed analysis of the Yixian formation of oil potential to make the right assessment.
