The Finite Element Analysis of the Rollers in a Rotary Steerable Drilling Tool

Abstract:

Rotary steerable system (RSS) is a system complete the oriented features in real-time while a drill string rotary drilling. It is a major change since the 1990s in directional drilling technology. RSSs drilling frictional and torsional resistance is small, has a high drilling speed, low cost, the well trajectory is smooth and easy to control, it is considered to be the development direction of modern steering drilling technology .When the system working ,drilling pressure and torque are passed by the thrust bearings in the controlled bend sub oriented tool; therefore it is necessary to analysis the rollers load distribution to verify the design parameters of variation cardan shaft, thrust bearings and roller are correct or not, This article analyzed thrust bearings rollers by ANSYS. Determine its maximum stress, etc. Providing more intuitive and scientific basis for its structural optimization ^[1].
