摘要
通过对鄂尔多斯盆地定北地区石油地质条件分析研究 ,认为该区二叠系山西组以三角洲体系沉积为主 ,石盒子期主要为河流相沉积 ;晚石炭系太原组和早二叠系山西组的煤系地层和暗色泥岩是上古生界的主要气源岩 ,二叠系山西组和下石盒子组为主要储层。经对比认为 ,定北地区石盒子组和山西组砂体发育 ,特别是主要含气层石盒子组底部砂体渗透性能好 ,有形成大规模岩性圈闭气藏的生储盖配置条件 。
Based on the analysis for Paleozoic petrology characteristics of Dingbei tract,the paper thinks Shanxi Formation mainly consist of of fluvial facies,the coal of Shanxi and Taiyuan Formation is the main oil source sand With comparing,it is considered that the sandstone of Shihezi and Shanxi Formation develop Especially,the main gas bearing bed lower Shihezi Formation,its permeability is high,it can form a mass lithologic deposit of good oil source rock、reservoir and cap rock.the prospect of exploration is better
