通过对鄂尔多斯盆地北部上古生界天然气储层的综合研究,发现中部伊陕斜坡带上的大型岩性气田,其储层为河流-三角洲沉积体系的河道砂体和三角洲平原分流河道砂体,在平面上自北向南呈长条状分布,小规模的构造型气田和含气圈闭位于盆地周缘,认为沉积格局受古构造背景控制,构造控制沉积相带,沉积相带控制着气藏分布,是影响鄂尔多斯盆地北部天然气藏的分布规律的主要因素,据此指出了该区下一步的勘探区域。
Through the comprehensive study of the Upper Paleozoic natural gas reservoirs in the northern Ordos Basin, it is found that the large-scale lithologic gas fields in the Yishan Slope Belt in the central part of China are characterized by fluvial-deltaic sedimentary systems and distributary channel sand bodies in deltaic plain. In the plane, there are long strip distribution from north to south. Small scale structural gas fields and gas traps are located at the periphery of the basin. It is believed that the sedimentary pattern is controlled by palaeotectonic background, tectonically controlled sedimentary facies and sedimentary facies control the distribution of gas reservoirs, Which is the main factor affecting the distribution of natural gas reservoirs in the northern part of Ordos Basin. Based on this, the next exploration area in this area is pointed out.
