LWD Rotary Steerable System
The total length of the rotary steerable system (including power supply, pulser, MWD, logging system and rotary steerable system) is no more than 16 meters. Due to drill string vibration, impact, annular pressure, rotary steerable system could transmit real-time data. With azimuthal gamma-ray imaging function, rotary steerable system can be widely used in reservoir geosteering.
It also has the function of rotary steering and near bit well deviation measurement, and could control well trajectory accurately when drilling tool is continuously rotating. In rotary steerable system, automatic computing equipment on the ground sends commands during drilling to control downhole instrument, without occupying additional operation time. Rotary steerable system has several control modes: steering mode, stabilized mode and so on. Downhole closed loop controls system automatically.
Tool maintenance is easy. Steerable sub can be disassembled on site, so as to ensure the smooth field operations. Completing the equipment of drilling tools on site needs about 2 to 3 hours, which is fast and convenient.

Hyper Cleaner
The hyper cleaner has the following functions:
1. Improve the carrying of debris. Carrying capacity of the mud on the sedimentary rock debris in the big stomach is improved, the formation of the rock debris bed is reduced and the migration efficiency of the cuttings is improved.
2. Reduce the probability of complex accidents in the underground. During the drilling of inclined or horizontal section, if there is large block falling, effective rolling can be carried out and small particles can be broken.
3. Improve drilling efficiency. The smooth flow of wellbore is improved, the lifting and lowering of drilling string are smoother, short trip time and well passing time are reduced. The mechanical drilling speed has been improved compared with conventional drilling, which improves production efficiency, shortens construction period and reduces construction risk.
