摘要

摘要: 在系统观察岩心、详细岩心描述和地层划分对比的基础上,从单井沉积相分析入手,结合地震、测井、古生物、大量的分析化验资料和岩相占地理条件研究成果,阐明了准噶尔盆地三个泉地区中侏罗统西山窑组和头屯河组的沉积相类型、沉积相特征、沉积砂体分布以及砂体形态,分析了中侏罗统西山窑组和头屯河组的沉积演化规律和沉积演化控制因素。研究表明准噶尔盆地三个泉地区中侏罗世发育温暖潮湿气候条件下的三角洲和湖泊沉积,分支河道沉积在三角洲中占主体地位,湖水向南后退导致河流入湖处形成大面积的三角洲平原沼泽沉积。因为三个泉凸起近邻盆1井西生油凹陷,并且其西部及南部发育中侏罗统三角洲砂体和湖泊砂体,所以是该地区最有前景的勘探目标区。

Abstract: Based on analysis of individual well sedimentary facies with numerous seismic data, logging data, paleobiologic data and other test data integratedly, the sedimentary styles of facies, shape and distribution of sandbodies were clarified and sedimentation variation principles and control factors of sedimentation in Middle Jurassic Xishanyao and Toutunhe Formation were discussed in the Sangequan area of Junggar Basin.Results showed that delta and lake deposits were occurred under warm and humid climate in Middle Jurassic, which was dominated by powerful distributaries channel deposit.When water retreated southward there was large proportion of swamp developed on delta plain.Sangequan area becomes a important target due to its close to western well Pen-1 source sag and is rich in good quality sandbody in the west and south.
