Near-bit MWD System

Introduction
Near-bit MWD System including survey sub and receiver. The survey sub is located between the screw stem and the drill bit with real-time dynamic azimuth gamma and inclination data measurement at the bit, which is electromagnetically transmitted to the receiver connected to the top of the screw stem, and then to the surface via MWD system.
Features
● Near-bit measurement
● Near-bit module inclination and dynamic azimuth gamma imaging measurement
● Wireless communication with data transmitted real-time across screw stem, compatible with all mud     types
Application
● Horizontal, ERD, and directional drilling
● Steering within formations with dipping beds

Environmental Parameters
● Operating temperature           Up to 175°C / 347°F
● Max. pressure                         120MPa / 17400psi
