摘要：

准噶尔盆地西北缘天然气按照成因类型可分为油型气、混合气和煤型气；按照赋存形式可分为溶解气、气顶气和凝析气.天然气在平面上的分布具有明显的分带性:油型气主要分布在八区以东、克一乌断裂上盘主体含油区的各层系中；煤型气主要分布于五区南克75井区上二叠统和下二叠统；混合气则分布于油型气与煤型气接合部的八区546井区上二叠统.

关键词: 准噶尔盆地, 天然气类型, 二叠系, 油气分布规律

Abstract:

Natural sas in the northwest margin of Junggar Basin could be classified into oiltype gas,mixed gas and coal-formed gas according to its genesis,and could also be divided based on the storing forms into dissolved gas, gas-cap gas and condensate gas. The distribution of different genetic gases may coincide with that of the source rocks:oil-type gasis mainly distributed in oil-bearing strata from Carboniferous to Jurassic in the main bidyo f the hangins wall of Karamay-Wurehe fault; coal formed gas is predominantly distributed in the Upper Permian Wuerhe Formation and Lower Permian Jiamuhe Formation of Ke-75 wellblock in the south of No.5 district; mixed gas primarily preserved in the Up-Per Permian Wuerhe Formation of 546 wellblock in No.8 district.
