Research and application on injection-production integration technology of ESP for offshore heavy oil thermal recovery

Year: 2025

Type: article

Abstract: 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.
