The Parameters Optimization that Based on the Finite Element Simulation of Hydraulic Injection Radial Drilling Technology

摘要

Using the technology of hydraulic injection radial drilling can effectively solve the problem of low permeability oilfield development. Aiming at the the problem that reducing the rock fragmentation efficiency because of the recoil force in the process of the construction of hydraulic injection radial drilling, study the velocity distribution under different diameter, calculate the recoil force, rock breaking force and propelling force, and optimize the process parameters of hydraulic injection radial drilling technology by using the numerical simulation method.
