摘要
By the study of modern deposition in Poyang Lake delta,planar morphology and structural features of underwater distributary channel and mouth bar were established. And the widths of two facies were established by statistics of dense well network data in Yonganzhen oilfield, then the quantitative training images were created. On the above basis, the delta front microfacies was simulated using multi-point geostatistics Sneisim algorithm. The results have the characteristics of matching to well point data, and planar morphology and size of different microfacies are constrainted by quantitative characteristics of the training images, which reproduces geometric characteristics and spatial structure of delta front distributary channel and mouth bar.
