Near-bit geological steering systems are mainly used to solve the problems of traditional geological steering instruments where the geological parameters and trajectory parameters are far from the drill bit and the measurement parameters are lagging, which makes it easy for the drilling trajectory to deviate from the reservoir and the effective reservoir drilling speed is low.
Intelligent rotary steerable drilling systems are drilling systems capable of providing guidance in real time during the drilling process, representing a significant revolution in directional drilling technology. Rotary steerable drilling offers advantages such as low friction and torque, high drilling speed, low cost, short wellbore construction cycle, smooth wellbore trajectory, and ease of adjustment and control. It can also extend the length of the horizontal section and is considered the future direction of modern directional drilling technology.
