生储盖组合划分新方案

A new plan for dividing source-reservoir-cap rock assemblage and its exploration meanings

传统的生储盖组合划分方案中不包括断层、不整合面 ,在油气运聚研究中强调输导层对油气成藏的作用 ,有一定局限性。我国复杂叠合型油气盆地具有断裂发育、不整合面多等特点 ,传统的生储盖组合划分方案难以满足此类盆地的勘探需要。提出的新方案强调了断裂、不整合面在生储盖组合划分中的重要地位 ,补充和完善了传统的划分方案 ,扩大和丰富了找油视野 ,有利于明确勘探方向、预测有利目标分布。

Traditional plans for dividing source reservoir cap rock assemblage only emphasizes controlling roles of transport layer to hydrocarbon, so they have very serious limitation and can't satisfy oil gas exploration needs in Chinese hydrocarbon basin because of complex geologic condition of too many faults and unconformities. The new plan emphasizes the important position of faults and unconformity to dividing source reservoir cap rock, makes up and perfects traditional plans for dividing source reservoir cap rock assemblage, enlarges finding hydrocarbon accumulation chances, so the new plan has important and realistic guide meanings to making clear exploration trends and predicting favorable exploration targets.
