Sandbody Identification in Single Channels of Multi-sandbodies

During the oilfield development by water-injection,in large-scale channel sandbody,some injection and production wells in the certain locations ware connectivity,where the conditions of injection and producing wells were poor.Further studies showed that there was a single sandbody boundary in such sandbody.Based on that situation,tracking and classifying single channel sandbody was necessary for recognizing the connectivity relation within the multi-sandbodies,accurately determining the water injection or incoming direction of oil-water wells,the method was to study it by using the limited data of well logging,well testing,coring and tracer.The multi-sandbodies,are classified according to sandbody partition and its areal relationship.Its classifying principle is described and it is used in X Oilfield,The special oil-water flow rules of meandering channel sand is summed up,by which a basis is provided for making a plan of oilfield adjustment.
