The Simulation of the Penetration Rate(ROP) of the Hydraulic Percussion Drilling

Yuanhua Lin, Wu Cai

Abstract

Benefiting from the dynamic model, the geometric structure model and the theory of the roller cone bit, I establish the mathematical model of the nager, the mathematical model of the real bottom hole and the mathematical model between the tooth and the rock of the hammer bit. Hence the penetration rate of the hydraulic percussion drilling can be predicted by simulation. Field tests show the models are reliable and the results which I predict are as precise as that in the field.
