坡洼过渡地区岩性油藏勘探实践——以齐家—鸳鸯沟地区为例

Lithologic reservoir exploration practice in slope-bottom land transition zone——A case study in Qijia—Yuanyanggou area

坡洼过渡地区是已往勘探常被忽略的构造带,但却是岩性油藏形成的有利场所。由于勘探形势的发展以及辽河油田公司各级领导对岩性油气藏勘探的高度重视,使得坡洼过渡地区岩性油藏勘探工作逐步得以深入,并不断取得新的勘探突破,对储量的贡献也逐步增大。本文以辽河坳陷西部凹陷齐家—鸳鸯沟地区为例,总结了坡洼过渡带岩性油藏的勘探成果,明确了下步勘探潜力,为勘探其他具有相似成藏条件的地区提供了借鉴经验。

Slope-bottom land transition zone was usually neglected in previous exploration but was favorite site of forming lithologic reservoir. As the progress of exploration and the importance that Liaohe oilfield leaders have attached to lithologic reservoir exploration, the work has been gradually deepened in slope-bottom land transition zone, exploration breakthroughs have been made constantly, and the contribution to reserves is increasing. This paper takes Qijia—Yuanyanggou area in the west of Liaohe depression as an example, concludes the exploration result of lithologic reservoirs in the area, explicates future exploration potential, and provides reference to exploration in other areas with similar conditions.
