Physical Simulation of the Displacement Laws for the Binary Compound Flooding in Offshore Oilfields

NI Ruichong, YANG Erlong, GAO Huijuan, LAN Meili

Abstract


The researches on EOR effects of the binary compound flooding by means of litho-eletric experimental principles and 3D physical simulation system. The pressure meters and resistivity measuring probe installed on the model can accurately detect the changes of the pressure and saturation fields, and then the production effects of the flooding system are evaluated. The experiments show that for heavy oil binary system, the viscosification of the polymer pre-slug and swept volume enlarging role can be fully played. It can not only drive out the remained oil on the main flow lines, but also displace out the remained oil on both sides of the lines through improving the displacement efficiency. After the binary compound flooding, the remained oil mainly exists on the shunt lines among the producing wells.
