Determining deviation parameters when sinking horizontal wells in soil

Abstract

A schematic diagram of a device for deflecting a hole trajectory during horizontally directed auger drilling is proposed. The problem of deflector interaction with soil under static loading is considered. Using modified Cam Clay model for clay soils of the Ansys finite element package, the parametric problem on determining the dependence of well axis deflection angle and the value of well deviation per running meter of its length on the bevel angle of the front plane of rock cutting tool is solved. The optimal value of the angle is calculated.
