Distinctive Features of the Wave Process in the Well Casing under Implosion

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

A numerical study has been made of the wave process in the casing string of the well, which is initiated by the difference of pressures in the imposition device and the well fluid surrounding it. To describe the implosion process, a mathematical model has been proposed that takes account of the presence of two phases, viscous effects, the compressibility of the gas, nonstationarity, heat transfer, turbulence, and other factors. The basic parameters of the implosion process have been calculated. The influence of the implosion-device length on generated rarefaction and compression waves in the well fluid has been established.
