摘　　要：准噶尔盆地滴南凸起下侏罗统八道湾组属扇三角洲前缘亚相。在岩心观察的基础上,结合物性资料,查明该区扇三角洲砂体内部主要发育泥质隔夹层和物性隔夹层;利用测井数据确立了隔夹层的岩电关系识别标准,探讨了隔夹层的平面、剖面分布范围,指出隔夹层主要分布在河道顶部、砂坝底部和分流间湾中央。结合注采井示踪剂的验证,明确了研究区储集层砂体的叠置连通关系与隔夹层的分布规律是影响注采效果的重要原因。The Badaowan formation of Jurassic in Dinan swell in Junggar basin is a front sub facies of fan delta. Based on the core observa tion and petrophysical property analysis data,this paper points out that muddy interlayers and varied petrophysical property interlayers are developed in the fan delta sand bodies in this area. The rock electric relationship identification standard for the interlayers is determined us ing logging data,their plane and profile distribution ranges are discussed,and it is suggested that the interlayers are mainly distributed at the top of the channels,the bottom of the sand bar and the central distributary bay,by which the quantitative knowledge database of the interlay ers is established. Combined with the tracer validation of injection production wells,it is concluded that the key reasons for influencing injec tion production relationship and effects are the superimposed connecting relationship of reservoir sand body and the interlayer distribution.
