Product Description

EM-Measurement While Drilling

Introduction

LHE754501 EMWD is a dual-telemetry wireless MWD system that can be utilized for both traditional mud pulse telemetry and EM wave signal transmission. The transmission mode can be switched according to the downlink commands from the surface system.

Features
EM has fast transmission speed and strong decoding ability, whichcan adapt to the signal transmission of different formation. Realize automatic mode judgment in the boreholeAutomatically judge transmission channel and intelligent decodinoat the sureface.

Application
Engineering service of unstable drilling medium Drilling engineering with high transmission rate requirements.Drilling engineering with dual system.
