【摘要】 通过录井、钻井、地震剖面等资料对泾河油田长8疏导体系进行了分析,得出该区存在砂体、断裂等基本疏导要素。通过连井剖面和录井资料对优质烃源岩、储集砂体和断裂相互间的关系进行了研究,确定了泾河油田长8成藏主控因素是:顶生下储式成藏模式,断裂是主要疏导体,断裂带附近区域的砂体规模大小决定了储集体的规模大小。更多还原

【Abstract】 Through the analysis of Chang-8translocating system based on the data of mud log,drilling and seismic section,this paper obtains major translocating factors such as sand bodies and breakage in the zone.By studying relations among high-quality source rock,reservoir sand and breakage with the help of the data of connected wells profiles and mud log,this paper argues that Chang-8reservoir is a terminal storage type accumulation model.The breakage is the major translocating channel.The sandbody size nearby fault zone decides the size of reservoir body.更多还原
