Embedding modeling method for internal architecture of point bar sand body in meandering river reservoir
摘要
Abstract
A new internal architecture embedding modeling method was proposed for the reservoir heterogeneity of lateral accretion shale beddings ( LA) of point bar sand body in meandering river reservoir. Based on the point bar 3D grid model and the internal architecture analysis results, three-order modeling technology links were applied to form a full set of embedding modeling technology process and the algorithm implementation, which includes 3D vector field lateral accretion pattern fitting modeling, the LA thickness distribution interpolation in the control of lateral accretion surface trend and partial grid subdividing model embedding process. And then, the validity of the modeling method was validated. The results show that the embedding modeling method can be used to establish fine 3D model of LA which conditions to wells, and the LA distribution between wells can be drawn from this fine model. An optimized grid description of different levels and scale architecture units was provided through partial grid subdividing model embedding technology.关键词
