| Abstract: | The
principles and construction of a downhole hydraulic surge generator for reservoir
fracturing are introduced. To improve the efficiency of fracturing and to remove the
blockages of organic origin in reservoir formations, a solvent type chemical is used as
working liquid in surge fracturing and thus a combinational stimulation technique is
established. The technology of this technique and the results of performing such
combinational treatments in 9 production wells(5 viscous oil and 4 normal viscosity oil
wells) at West Huanxilin Oil field are described. |
