Perforating Technology For Booster Multistage Blast

Perforating technology for booster multistage blast through booster devices produces pressure,utilizing transmission pressure principle of liquid and firing the next detonator in order to achieve the goal of multi-stage inition, so that perforation process is done.This technique has largely reduced the usage of interbedded gun,decreasing engineering accidents due to leaking,failed blast,therefore,increasing success ratio of transmission blast safely.Finite element method and fluid analysis program and the confining pressure tubing in underground pressurized pipe under the action of deformation and fluid within the well under a certain pressure and the resulting compression of the relevant parameters and the pressure loss along the numerical simulation And optimization for the multi-stage booster detonation provide the scientific basis of technology to improve product safety and reliability and availability, reduce the cost of experiments. This paper developed a pressure booster devices, high temperature, partitions Booster margin test.This paper describes the design of pressurized multi-level initiation mechanism and technical indicators, and the Device and gunpowder booster design was studied. Developed multi-stage booster detonation device on-site role in experiments, and achieved very good results.
