Product Description

Near-bit MWD System

 

 

Introduction

The XZ-NBMS series of near-bit measurement systems are jointly developed by the CNPC Xibu Drilling Engineering Company Limited and Beijing Liuhe Greatness Technology Co., Ltd. The system includes transmission module and receiver module. The transmission module is located between the mud motor and the drill bit, and it can dynamically measure the azimuth gamma and inclination near the drill bit in real-time. The measured data is transmitted to the receiver module connected to the mud motor through electromagnetic waves, and the near-bit measurement data is then transmitted to the surface through the MWD system.
