PRACTICE AND MECHNISM DISCUSS OF DEPTH PROFILE CONTROL IN THICK LAYER

From remaining oil distribution discussing, the aim of depth profile is to dig the potential of thick layer where bigger difference of permeability exist Testing date analysis is said that the economic effect of depth profile would be improved greatly with proper design. Field application in Sazhong Oilfield was introduced. The data of two wells shown that the depth profile technology can enhanced oil recovery obviously either combine with water drive or with polymer drive.
