摘要
以济阳坳陷为例 ,分析了湖相深水油页岩段的岩性、电性及地震反射特征 ,研究发现 :湖相深水油页岩段为陆相层序地层的密集段之一 ,基本对应三级层序的最大湖泛面 ;该油页岩段具有较高的有机质丰度和良好的有机质类型 ,为优质烃源岩 ,且均布于凹陷异常高压带内 ,可向不同体系域中各种砂体供油。因此 ,深水油页岩密集段的识别及追踪 ,对于层序地层划分、烃源岩评价和油气勘探均具有重要意义。
The research on lithology, logging data and seismic reflection signature of limnic deepwater oil shale in Jiyang depression shows that its oil shale section is one of intensive sections of continental sequence stratum, which basically corresponds to maximum lakeflood surface of the 3rd order sequence. The oil shale section contains the richer organic matter and good organic type, which is the excellent source rock, and even distributes in overpressured zones of sag, it supplies hydrocarbon to every kind of sand bodies in various system domains. Therefore, identifying and tracing of intensive section of oil shale in deep water is of great significance on sequence stratum division, evaluation of source rock, and oilgas exploration.
