鄂尔多斯盆地是我国第二大中、新生代沉积盆地,属于多旋回叠合含油气盆地,是我国陆上油气勘探最早的盆地,也是我国石油工业的发源地之一。本文从沉积相、储层等方面,对鄂尔多斯盆地延长组油藏地质特征进行了分析,探究了油藏储层岩石特征、成岩作用、孔隙结构以及油气富集规律,为鄂尔多斯盆地的油气开采提供了必要的数据支持,也为油气勘探建立了工作思路。
Ordos Basin is the second largest Mesozoic and Cenozoic sedimentary basin in China. It belongs to multi-cycle superimposed petroliferous basins, and is one of the earliest inland oil and gas exploration basins in China. It is also one of the cradles of China’s oil industry. In this paper, the geological characteristics of the Yanchang Formation reservoirs in the Ordos Basin are analyzed from sedimentary facies and reservoirs, and the characteristics of rocks, diagenesis, pore structure and hydrocarbon enrichment in the reservoirs are explored, and the oil and gas exploration in the Ordos Basin is provided The necessary data support, but also for oil and gas exploration established a working train of thought.
