【摘要】 以岩心相、测井相、地震相为标志,通过对中亚南部湖盆Aryskum组古地理背景、砂体展布、水动力条件、沉积构造及地球物理响应等进行综合研究,认为其属于浅水粗粒辫状河三角洲沉积环境,主要发育浅水辫状河三角洲前缘亚相的水下分支河道和支流间湾沉积微相,其中,水下分支河道比较发育,不同方向的河道相互叠置,平面上连片分布,可形成有利的储集砂体。更多还原

【Abstract】 Based on core,logging and geophysical data,an integral study was conducted on paleogeographic background,sandbody distribution,hydrodynamic force condition,sedimentary structure and geophysical response of South Central Asia in Aryskum Formation.It is considered that it belongs to shallow and coarse braided river delta,underwater distributary channel and underwater interfluve are the main sedimentary microfacies,in which nnderwater distributary channels are well developed,channels from different directions superpose and stretches over sandbody spreaded in the plane,it is the favorable reservoir.更多还原
