摘　　要：近几年在鄂尔多斯盆地中部已发现多个储量规模上百亿立方米的天然气气田。富县勘探区位于该盆地的南部 ,该区奥陶系马家沟组为蒸发潮坪相沉积 ,具备形成天然气气藏的物质基础 ;本区上古生界处于生烃中心 ,气源充足 ;本区位于北部古潜台的延伸方向是有利的天然气勘探目标区。本文通过综合分析对富县勘探区古生界天然气勘探提出部署意见。Several large natural gas fields,in which the reserves are more than 1 00×10 8m 3，are discovered in Eerduosi basin for the last few years.On the South of the basin,the Majiagou Formation in Ordovician system in Fuxian explora tion region are evaporated tidal flat facies sedimentation,in which have the bas e of forming natural gas reserve.The upper paleozoic is in the center of hydrocar bon forming,which have plenty of gas resources,which is also the favorable objec t regions of natural gas exploration on the trend of north of buried platform.Ha ving been comprehensive analyzed,the project which explorate the natural gas are presented.
