陕北地区侏罗系油藏古地貌特征与油气富集规律研究

摘要

鄂尔多斯盆地陕北地区侏罗系延安组具有丰富的油气资源，油藏富集不仅受控于生油岩、沉积微相等因素，而且主要受古地貌条件控制。本文从研究侏罗系油藏特征出发，分析侏罗系古地貌形态特征，划分古地貌单元，最后得出侏罗系古地貌与油气富集规律，从而进一步指导油气勘探开发工作。%Jurassic ordos basin in shanbei region yanan group has abundant resources, reservoir enrichment controlled by not only oil source rocks, sedimentary microfacies equal factors control, and is mainly affected by the ancient geomorphic condition control. This paper studies the Jurassic reservoir characteristics, analyzes the Jurassic paleogeomorphology morphological characteristics, differentiate paleogeomorphology unit last, it concludes with the Jurassic paleogeomorphology oil-gas accumulation rule, thus further deep-water oil and gas exploration development work.
