摘要： 通过岩心、测井、地震以及分析化验等资料,对准噶尔盆地滴南凸起二叠系梧桐沟组进行了层序地层分析以及沉积相的识别,进而研究了层序沉积体系的分布配置关系,揭示了探区主要气藏分布规律。研究认为,滴南凸起二叠系梧桐沟组可以划分为2 个三级层序SQⅠ-1 和SQⅠ-2,SQⅠ-1 为辫状河三角洲沉积,主要发育水进体系域和高位体系域,而SQⅠ-2主要发育水进体系域,为泛滥平原沉积。SQⅠ-1为主要产气层段,该层段有利油气聚集区主要位于构造隆起区所发育的辫状河三角洲前缘河道砂及河口砂坝上。

Abstract: Using the data from cores, well logging, seismic profile and core lab, the sequence stratigraphy analysis and sedimentary facies identification of Wutonggou formation of Permian in Dinan swell in Junggar basin are conducted. The distribution and allocation relations of the sedimentary sequence system are studied, revealing the distribution regularity of the major gas reservoirs in this area. Wutonggou formation is divided into two third-order sequences—SQⅠ-1 and SQⅠ-2 ,SQⅠ-1 is sediment of braided river delta, mainly developing transgressive system tract (TST) and high system tract (HST), while SQⅠ-2 is flood plain sediment, mainly developing TST. SQⅠ-1 is the main producing gas reservoir section, in which the favorable oil-gas accumulation zones are mainly located in areas of channel sand and channel mouth bar in braded river delta front developed on the tectonic uplift.

Key words: Dinan swell, Permian, Wutonggou formation, sequence, sedimentary facies
