Study on the Identification of Composite Sand Body Single Channel by Well Seismic Combination

Abstract

The single channel sand body is a relatively independent unit in the reservoir. The accurate identification of the single channel sand body in the composite channel sand body is an important work for the exploitation of the reservoir in the high water saturation late stage, and is also a difficult point in the study of the reservoir. This paper discusses the basic research and identification methods for identifying the single channel sand body in the delta distributary plain composit sand body in the oilfield. The understanding of composite sand bodies is deepened, and the operability of single channel sand body identification is also improved, which has achieved certain results in oilfield development and application.
