Establishment And Simulation Of Magnetic Guidance Drilling Model For Trenchless Engineering

The guided positioning technology of trenchless has not been developed in China.Most of the guidance tools and technologies have long relied on abroad and are expensive to limit their own development.Based on the application of magnetic-oriented drilling in the field of oil drilling,this paper studies the location of trenchless magnetic guidance.The main work done is as follows:(1)The basic parameters of trenchless magnetic directional drilling are described.The method of drilling attitude measurement based on geomagnetic field and gravity field is studied.(2)The guiding model based on the ground laying coil is deduced,and the physical simulation experiment is carried out inside and outside.The experimental results are verified and analyzed by MATLAB software.(3)The guiding model based on two solenoid magnetic source is deduced,and the physical simulation experiment is carried out outside.The experimental results are verified and analyzed by MATLAB software.(4)The advantages and disadvantages and adaptation conditions of the two methods are analyzed.
