摘要：

鄂尔多斯盆地伊陕斜坡北区奥陶系顶部风化壳圈闭决策分析表明,以残台、残丘为代表的10个圈闭中,11号、8号、6-7号和4号圈闭累计面积大、资源量丰富、经济效益值高、第一口井为发现井的概率高,是具有远景的圈闭,15号、13号和12号次之,14号和9号较差。

Abstract:

The decision analysis of the traps of the upmost Ordovician weathering crust in the north area of Yishaan slope, Ordos Basin indicates that among the 10 traps represented by relict tables, unakas, the traps of No.11, No. 8, No. 6-7 and No. 4 have relatively large cumulative areas,richer gas resources, higher economic benefit, lower critical probability, higher probability for the first well to be the discovery well, and these traps are more prospective in gas exploration. The traps of No. 15 - 13 are secondary: traps No. 14 and No. 9 are the last.
