| 摘 要： | 最近几年鄂尔多斯盆地西部及中南部延长组深层的油气勘探取得了重大突破，探明石油地质储量数亿吨，研究鄂尔多斯盆地延长组深层油气聚集规律具有重要现实意义。通过鄂尔多斯盆地延长组深层源、储、运聚与油藏关系的系统分析，揭示了延长组深层油气聚集规律。研究结果表明，鄂尔多斯盆地延长组深层油藏主体为“上生下储”型岩性油气藏，油气聚集具有“源控区、相控带、压力差控位”的规律，具体为：延长组深层油区分布于近烃源岩区，已知油藏基本分布于三角洲前缘水下分流河道叠合连片区带，大多数长8油藏分布在长7油层组与长8油层组异常压力差低值背景下的相对高值区。

| Abstract: | A great breakthrough has been made in oil exploration activities in deep zones of the Yanchang Formation in the western and southern-centeral Ordos Basin in recent years,where several hundred millions geological oil reserves have been confirmed.Therefore,it is of great practical value to study oil accumulations in deep zones of the Yanchang Formation in the Ordos Basin.The present paper revealed oil accumulation rules in deep zones of the Yanchang Formation by systematically investigating interrelationships... |
