The strength safety of perforated string is the premise of safety production of oil well test, detonation parameters of perforating charge is an important factor that affects strength safety of perforated string. On the basis of correctly calculating the detonation parameters such as detonation temperature, detonation heat, detonation volume, detonation pressure and detonation velocity, then adopting the related thermodynamic theory and analyzing the surge pressure of perforated interval, "pocket"of down hole and the packer, thus get the impulsive load of perforation moment and then according to Buckling theory of string to analyze the strength safety of perforated interval tubing string. Considering the fitting sex between the analytic method of the strength safety of perforated interval tubing string and the practical situation of real well cases is very good, and the result of analysis can reflect the state of strength safety of perforated interval tubing string at the moment of detonation, therefore this method can provide primary reference analysis data for the design of strength safety of perforated interval tubing string.
