![]() ![]() For this reason, the three-dimension finite element analysis method was used to perform numerical calculations for the deformation of tubing string and the distribution of axial stress based on three typical load conditions (setting load, fracturing load, and well testing load of Well MJ4) a process for calculating the mechanical behavior of a completion and testing tubing string containing an expansion joint was then developed. During the completion job, plastic deformation occurs in the tubing string, so it is very necessary to figure out at which stage of the completion job plastic deformation occurs on earth. In Well MJ4, Tarim Basin, the testing tubing string is 6617 m long and the bottom-hole pressure during the testing is 101.63 MPa. ![]()
