摘要
鄂尔多斯盆地定北地区天然气勘探和研究程度均相当低。通过对山西组岩石学特征、物源分析、沉积特征研究,结合邻区资料及区域上的勘探成果,认为山西组沉积期,物源主要来自于盆地北部,山一段沉积期,主要为辫状河三角洲前缘沉积,而山二段沉积期,过渡为辫状河三角洲平原沉积。三角洲前缘的水下分流河道砂岩为最优质的储集层。
The degree of natural gas exploration and understandings of geological conditions is lower in Dingbei area, Ordos Basin. It believes that main source of sediments come from northern Ordos basin when Shangxi Formation sediment, and the bottom of Shangxi Formation are braided delta front sediments, but the top of Dhangxi Formation transited brained delta plain sediments, subaqueous distributary channel sandstones of delta front are fine reservoir.
