Research on Multi-tube Fittings Connector Protector for Thermal Recovery
Because of the temperature effect during heat injection of the injection-production integrated string of offshore heavy oil thermal recovery,there are pull-out accidents of the fittings connector.In this paper,a new fittings connector protector was designed.By studying the influence of structural parameters on mechanical properties of fittings connector,the structure of the fittings connector was determined.Based on ANSYS static simulation,the cut-in state of fittings connector under actual work-ing conditions was analyzed,and the accuracy of simulation results was verified by room temperature tension test.The test results show that the anti-pulling force of the new multi-tube fittings connector protector reaches 18.62 kN.The pipeline cut-in depth of the three edges is consistent with the maximum deformation of simulation,and the error is less than 6%.The multi-tube fittings connector protector developed in this paper is used in 6 wells without any abnormal condition.
