鄂尔多斯盆地油、气、煤成藏机理及分布规律

摘要：本文通过对鄂尔多斯盆地石油、天然气和煤成藏因素和分布规律的系统研究，研究表明，鄂尔多斯盆地石油、天然气和煤炭资源分布呈规律性叠置，不同构造单元叠置的类型和样式具有较大的差异性，为减小勘探风险和降低勘探成本，应进行石油、天然气和煤综合勘探的思路。陕北斜坡是石油、天然气、煤和非常规煤层气综合勘探的地区，并可一井多探；天环坳陷、西缘掩冲带位于盆地的西部，目前在该区域已发现油田、气田和煤田，各种类型能源矿产成藏条件优越，是石油－天然气－煤综合勘探地区；伊盟隆起、晋西挠褶带、渭北隆起位于盆地的北、东、南的边缘部位，侏罗纪煤系广泛发育，是煤和煤层气的勘探区。

Accumulation mechanism and distributing regulation of oil,natural gas,coal in Ordos basin

Ordos basin is prolific in petroleum,natural gas,and coal resources,and is an important energy base in our country.The petroleum distributes in Jurassic to be subjected by the eroding river valley and Triassic to be subjected by depositional system of delta.The natural gas distributes in Upper Paleozoic to be controlled by the delta depositional system and Lower Paleozoic to be controlled by the fossil weathered crusts.The coal distribute in Permo-Carboniferous,Triassic and Jurassic,which has been controlle...
