The description technology of inner lateral accretion within point bar of meandering river under the condition of infill drilling well pattern is introduced. On the basis of fine geologic research conducted in Daqing Oilfield, the reservoir heterogeneity is studied. Based on the analysis of formation sequence and structure elements, the concepts in terms of lateral accretion structure characteristics, as well as description method and prediction method for the interlayer located in point bar of meandering river are proposed. These methods provide effective way for the fine study on sedimentary sand body of meandering river and the further development of remaining oil within thick reservoir. The study results were applied to the locus design of horizontal well in Daqing Oilfield, and good result has been achieved.
