摘　　要：永宁油田D227井区长6储层资源潜力较大,但存在非均质性强、油水分布规律难辨、油水解释符合率低等问题。综合钻井、测井、录井及试油试采等资料,研究发现D227井区延长组长6油藏属于典型的岩性油气藏,油水分布平面上受沉积相带和砂体展布的影响明显。纵向上,长6油层组呈现“上油下水、双向遮挡”的油水分布模式,其中的优势油层主要位于长6_(1)^(1)、长6_(2)^(1)小层。The resource potential of Chang 6 reservoir of D227 well area of Yongning Oilfield is great.However,its problems such as strong heterogeneity,unclear oil-water distribution law,and low compliance rate of oil-water interpretation have profoundly affected the efficient development of the area.Based on the comprehensive data of drilling,well logging,mud logging and production test,it is found that Chang 6 Reservoir of D227 well area is a typical lithologic reservoir.And the oil-water distribution plane is obviously affected by the sedimentary phase belt and the sand body spread.Vertically,the oil-water distribution pattern of Chang 6 reservoir group is upward oil and downward water,bidirectional occlusion.The dominant oil layers are mainly located in Chang 6_(1)^(1) and Chang 6_(2)^(1) layers.
