兴隆台—马圈子古潜山油气藏勘探研究

Xinglongtai-majuanzi buried hill reservoir exploration study

针对兴隆台—马圈子古潜山油气藏基底结构和构造不清楚、古潜山裂缝预测难度大等问题进行了精细的分析,形成了重、磁、电资料确定潜古山轮廓,地震资料落实和描述圈闭,VSP地震测井中途测深的1套独特的古潜山勘探技术,并建立了古潜山翼部成藏的新模式。2004年古潜山带上报预测石油地质储量6442×104t,含油面积24·2km2,展示了辽河坳陷西部凹陷古潜山油气藏勘探的良好前景。

Xinglongtai-majuanzi buried hill reservoir is precisely analyzed for its base structure and fractures. A series of technologies has been established for buried hill exploration, including buried hill delineation by gravity, magnetic and electrical data, trap description by seismic data, and drill-stem VSP logging. A new model of reservoir forming on buried hill flank is also set up. The reported OOIP in 2004 was 6442×10~4 t and oil-bearing area was 24.2 km^2,showing a bright future of buried hill reservoir exploration in the western sag of Liaohe depression.
