【摘要】 温米地区紧邻丘东生烃凹陷,油气资源丰富,油藏类型多,油水关系复杂。经过近20 a的勘探,中浅层剩余的构造型圈闭越来越少,岩性油气藏勘探程度低,以原有的"构造控藏、层状边水"认识指导勘探的难度越来越大。利用现有钻井、测井、地震、试油及分析化验资料,寻找有利的勘探目标是亟待解决的问题。通过精细地质研究,认为该区油气成藏受岩性、断裂影响大,且岩性控藏明显,表现为同一构造背景上呈现"一块多藏、一砂一藏"的油水分布特征,并在此认识的基础上指出下步精细勘探的主要方向。更多还原

【Abstract】 Wenmi area which is located next to Qiudong hydrocarbon- generation sag is featured by abundant hydrocarbon resources,multi reservoir types and complex oil- water distributions. After exploration for nearly two decades,the remaining middle- shallow structural traps are decreasing and the exploration degree of lithologic reservoirs is low,which makes the exploration in this area much more difficult just according to the original principle of"structural controlling,laminar edge- water". It is urgent to identify favorable exploration targets based on the existing drilling,logging,seismic,testing and other analysis data. The refine geologic study indicates that hydrocarbon accumulation in this area is greatly influenced by lithology and fault. Moreover,the control by lithology is reflected by "multi reservoirs in a block,and single reservoir in a sandbody"oil- water distributions in a structure. On this basis,the future exploration target is proposed.更多还原
