摘　　要：综合运用岩心、录井、测井、岩石薄片等资料对研究区沉积相进行精细研究,结果表明:滴20井区八道湾组J1b11发育近岸水下扇沉积体系,可进一步识别出3种亚相、7种微相;沉积相带对有利储层具有明显的控制作用,辫状沟道及沟道侧翼微相主要发育砂砾岩、砂岩等岩相类型,孔渗较好,是研究区的有利储层沉积相带,可作为未来油气评价和开发的主要目标区。The sedimentary facies in the study area were studied by using core、logging、well logging and rock thin section data,the results showed that:the offshore subaqueous fan sedimentary system is developed in Badaowan formation J_(1)b_(1)^(1) in Well Di20,and 3 subfacies and 7 microfacies can be further identified;The sedimentary facies belt has an obvious control effect on the favorable reservoir,The braided channel and its flank microfacies mainly develop the sandstone and gravel facies,The pore and permeability are good,so it is the favorable reservoir sedimentary facies belt in the study area,which can be used as the main target areas for future oil and gas development and evaluation.
