Introduction

Stick-slip Vibration Measurement Sub, can measure, analyze, record and transmit axial vibration, lateral vibration, stick-slip grade and other parameters in real-time . The tool evaluates downhole drilling safety and provides real-time warning of possible damage to MWD and other downhole instruments. By uploading vibration and stick-slip data in real time, the operation mode can be adjusted in time to maximize drilling efficiency while ensuring drilling safety.

Features

● Independent R&D with magnetic communication patent technology.

● Compatible with kinds of MWD.

● Low power consumption, ensure the original operating time.

● Provide standard protocol interface. It can be customized.
