摘要: 鄂尔多斯盆地中部气田位于稳定克拉通中央古隆起东北部,是一个与奥陶系海相碳酸盐岩有关的风化壳型气田。对其古构造、地层出露状况和沟槽特征进行了分析,采用残余厚度法对奥陶系古地貌进行了研究,分析了地貌单元与油气富集的关系。

Abstract: Central Gas Field located in the center of Ordos Basin is formed on the paleo-uplift in the north-eastern boarder of the stable craton. It is a weathering crust type gas field relative to marine carbonate rock. The characters of palaeostructure,lost stratum and the erode karst flute were analyzed. The methods of residual thickness were used to recover the paleogeomorphic features of the Ordovician. The paleokarst landform types are relative to the accumulation of natural gas.

Key words: Ordos Basin, Central Gas Field, weathering crust, palaeostructure, paleogeomorphology, hydrocarbon accumulation
