AB - Combined with the requirements of offshore marginal oilfield/non-work over  rig platform, the injection-production integration technology of electric  pump is constructed by developing the Christmas tree of electric pump,  wellhead cable and control pipe-line crossing device, production packer and  safety joint. Indoor and field tests show that the test results show that  the injection-production integrated supporting tool of cast-fishing  electric pump has a temperature resistance of 180°C and a pressure  resistance of 21 MPa, which meets the needs of marginal oilfield/non-work  over rig platform, shortens the operation cycle, reduces the operation  cost, and has a high promotion and application prospect.
