摘要: 吐哈盆地侏罗系广泛发有冲积扇、河流、湖泊、扇三角洲、辫状河三角洲及曲流河三角洲相沉积。其中的中侏罗统西山密组、三间房组和七克台组辫状河三角洲前缘水下分流河道、序三角洲前缘水下分流河道、辫状河河道砂坝及演浅湖滩砂等相带是良好的储集砂体,其纵向发育和横向展布是今后油气田勘探的一个重要研究课题。

Abstract: Alluvial fan, fluvial, lake, fan delta, braid river delta and meandering river delta facies sediments are widely developed in Jurassic in Turpan-Hami basin. The good reservoir sandstone bodies include the facies belts of underwater distributary channel of braid deltas front, underwater distributary channel of fan deltas front, stream channel bar of braid river and beach sands of shore shallow-lake in middle Jurassic (Xishanyao Formation, Sanjianfang Formation, Qiketai Formation). Its vertical development and lateral spreading will be an important subject of oilfield exploration in the future.
