辽河齐家潜山油气藏特征研究及潜力评价

利用岩心、测井、地震等资料,对齐家潜山储层岩性和物性等进行综合研究,并从构造运动、运移通道、生储盖配置等方面分析了潜山成藏条件:剧烈的构造运动控制了潜山的演化形成,为油气藏提供了良好场所;断层和不整合面为油气运移提供条件;圈闭与油气运移的时空配置关系,决定了能否聚集油气;良好的盖层使潜山圈闭聚集成藏。研究认为齐家潜山是倒装式成藏模式,并预测了潜山油气圈闭有利区为齐古6井区和齐2-12-14井区,对下一步勘探具有指导意义。

Reservoir characteristics and the potential evaluation in Liaohe Qijia buried hill

Based on the core, log and seismic data, this paper carried on a compreshensive study on Qijia buried hill reservoir lithology and physical properties.analyzed the buried hill reservoir condisitions tectonic movement, migration pathway, reservoir-cap allocation. Intense tectonic movement controlled the buried hill evolution provided a good place to hydrocarbon reservoir; faults and unconformities provided conditions for the oil and gas migration; trap and migration of the relationship between space-time configuration determined whether the oil and gas can be accumulated; good cover layer to buried hill trap accumulation. In this paper it's thought that Qijia buried hill belonged to a flip-style accumulation model, and predicted a favorable area for the buried hill oil and gas traps is in the ancient Qigu 6 and Qi 2-12- 14 Well, which provided guidance to the further exploration.
