随着深盆气理论在鄂尔多斯盆地的应用,盆内上古生界的气藏不断被发现,储量逐年上升。关于深盆气的气源问题人们一直争论不休。根据现代天然气和煤层气地质理论,在搞清鄂尔多斯盆地深盆气地质条件基础上,用先进的煤层气专项分析测试仪器进行了大量分析测试,证实了鄂尔多斯盆地中北部丰富的煤层气是上古生界山2段和盒8段深盆气藏的补充气源这一客观事实。

With the application of deep basin theory in the Erdos basin, gas reservoirs of Upper Paleozoic were discovered continuously and reserve went up year by year. The resource of deep basin gas is one of the problems people have been always arguing about. By use of geologic theories of natural gas and Coalbed Methane (CBM) and advanced special analytical and test apparatus, through large quantities of analysis and test, this paper approved this objective fact that the rich CBM in the middle to northern part of Erdos basin is the complementary gas resource of the deep basin gas in Shan 2 and He 8 on the basis of clear geologic conditions of deep basin gas in Erdos basin.
