In order to ensure safe and efficient mining and improve the efficiency of drilling construction, intelligent drilling technology has been studied in China. This technology is another development on the basis of automation. In addition to the automatic execution of the construction process, it also has the characteristics of intelligent perception, intelligent decision-making and intelligent correction. This technology requires engineering parameter measuring equipment to obtain the engineering parameters such as torque, WOB, inner and outer annulus pressure, rotation speed, vibration, temperature, etc. near the drill bit at the bottom of the hole in real time, so as to realize the real-time monitoring of the drilling process parameters at the bottom of the hole and the stress state of the drilling tool in the process of directional drilling, and increase the effective extraction distance of the drilling hole.

Drilling Technology

The directional well drilling technology is extensively utilized and developed throughout the world. However, series of drilling problems occurred in the operation process of directional drilling. In order to reduce the friction of drilling tools, an oscillation tool with a fluidic amplifier has been field tested, and the pressure pulse of oscillation tool has been obtained. Field test results have shown that the oscillation tool has an extensive flexibility to directional well drilling, and the oscillation tool could stably actuate the drilling tool to have reciprocating vibration, which contributes to the friction and drag reduction of drilling tools. Furthermore, it can be concluded that the pressure pulse value generated by pumped fluid varies with input flow rate, and the pressure of oscillation tool increases while the flow rate is increasing. In addition, the motion frequency of the oscillation tool is exponentially increasing with the raise of pumped flow rate.

Drilling Technology

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].
