Abstract
Particle impact drilling is a kind of rock breaking method, that high speed metal particles and fluid were given priority to be used to jointly break rock, and mechanical drill bits were supplemented. It is an effective means to solve the hard and abrasion-resistant drilling problems in deep and ultra-deep well drilling. Accelerate process of the particle in the fluid are analyzed, In view of the cone type nozzle, the equations of fluid motion and acceleration simulation of particle were established, and resolved the mathematical model, using Fluent software simulation platform, simulation verification was performed for the acceleration of particles and fluid in a straight cone nozzle. The calculation results were identical to the simulation results. It proved the mathematical model is correct. The results can be used to determine rock parameters for particle jet impact.
