摘　　要：根据钻井、测井及岩心分析化验资料,结合前人研究成果,认为S158井区盒8下亚段为辫状河三角洲平原沉积,盒8上亚段为曲流河三角洲平原沉积。对沉积相平面图的传统编制方法进行改进,综合考虑砂/地比值、测井曲线、储渗砂层发育状况3方面因素,分别建立盒8上亚段、盒8下亚段沉积相平面图编制标准并绘制沉积相平面图,认为最有利储集砂体主要为不同时期沉积的高能河道中的心滩、边滩叠置砂体,次为主河道充填砂体以及河床滞留沉积叠置砂体。After the study on some data from drilling,well logging and core analysis,it is considered that the lower Shiehezi 8 Member,S158 well block,is a deposition of braided-river deltaicplain whereas the upper is a deposition of meandering-river deltaic plain. In this study,traditional methods to establish sedimentary-facies plane view are improved at first; and then some establishing standards for both upper and lower members are done and a new sedimentary-facies plane view is mapped out based on three factors including sandstone percentage,well-logging curve and reservoir growth. In addition,it is found that the most favorable reservoir bodies are mainly overriding sandbody of both channel bar and point bar in high-energy channel deposited in different stages,secondarily overriding channel-filled and riverbed-deposited sandbody.
