摘要： 华北克拉通经历了印支、燕山和喜马拉雅期构造运动,主要在从西向东的构造挤压力和东部的构造拉张力的联合作用下,把克拉通分割成阿拉善、鄂尔多斯、山西、河淮、胶辽和北部的内蒙古几个地块。在鄂尔多斯的上古生界煤成气资源十分丰富,根据烃源运移和储集层、圈闭条件分析,在这里应该有6个含气带,即乌达—银川、杭锦旗、东胜—靖边、神木—绥德、米脂—延安和天环坳陷。

Abstract: The term of North China Craton was firstly proposed by Mr. ZHAO Chong-yuan, which refers to that craton is separated as several blocks like Arashan, Ordos, Shanxi, Hehuai, Jiaoliao and those of northern Inner Mongolia by joint process of structural compressional pressure from west toward east and structural extension force from east following the Indo-Chinese epoch, Yanshan epoch and Himalayan epoch. The Upper Paleozoic in Ordos basin is a horizon given with coal-formed gas. Based on analyses of hydrocarbon source rock, petroleum migration, accumulation and trapping conditions, it is believed that there exist six gas bearing zones, including Wuda-Yinchuan, Hangjinqi, Dongsheng-Jingbian,Shenmu-Suide, Mizhi-Yan'an and Tianhuan depressions.

Key words: craton, source rock, secondary migration, Late Paleozoic, Ordos basin, gas field
