Structure Dynamic Response Analysis of Pipe String under the Action of Perforating Detonation Wave

Abstract:

Impact load of perforation will result in strong vibration of downhole string, string operated such as bending fracture accidents. Considering the clearance between string and casing, using space beam and spring element to solve the nonlinear contact problems between oil jacket, established the numerical model of string structure dynamic response analysis in horizontal well. Extracting downhole perforation pressure wave monitoring data, using the finite element software ANSYS, analyzed the dynamic response of the tubing under perforation of detonation shock wave impact, got the displacement of the tubing、acceleration time history. The results show that, without packer, the maximum Mises equivalent stress in the end of the string, the deformation and stress changes in deflecting section of the tubing string are bigger than in vertical Wells.
