摘　　要：综合运用岩心、测井资料,在区域沉积体系研究的基础上,依据沉积结构、构造,沉积序列、及测井响应特征,确定陆相环境下的浅水辫状河三角洲沉积为研究区上古生界石盒子组的沉积模式,其沉积亚相类型主要为三角洲平原和三角洲前缘,微相可细为分流河道/水下分流河道沉积、心滩沉积、分流间湾及河口坝/远砂坝等类型。Based on the study of regional sedimentary system,the core and logging data are comprehensively used,According to the sedimentary structure,structure,sedimentary sequence and logging response characteristics,It is determined that the shallow Braided River Delta in the continental environment is the sedimentary model of the upper Paleozoic Shihezi Formation in the study area,The sedimentary subfacies are mainly delta plain and delta front,The microfacies can be divided into distributary channel / underwater distributary channel deposit,core beach deposit,distributary Bay and mouth bar / far sand bar.
