摘要
Based on the theoretical model of modern deposition and outcrop, using Miall’s graded interfacial and the analysis method of structural element, and with the scale analysis and mode fitting for the research ideal, the architecture of meander channel sandbody was scaled in the SⅡ1+2b sedimentary unit of the second western region of Sabei Oilfield combined with the information of dense well pattern. Based on this, the third boundary of inside sandbody based on well point data (3D geology model of lateral accretion interlayer) was established, which provided geologic basis for comprehensive adjustment and remaining oil potential tapping at the late stage of high watercut.
