FIELD APPLICATION OF THREE PHASE FLOW COMPLEX HIGH ENERGY PERFORATION AND FRACTURING TECHNIQUE

The extended perforation means that perfect or super-perfect status can be achieved for the target zone through one-off perforation, that is, the reservoir damage resulted from the drilling, completion and perforation can be eliminated thoroughly through one-off perforation. The three phase flow complex high energy perforation and fracturing technique is the one developed on the basis of two phase flow complex perforation technique. It combines the shaped charge perforation (89 shots), the controllable solid propelling agent and the sand fracturing together, and thus increases greatly the flow degree and rate of the fractured wells. Field application indicates that this technique possesses extensive suitability for the oil and gas reservoirs with different physical property and burial depth. It is worth of popularizing and is another new technology for plug removal of oil and gas reservoirs.
