1. Brief Introduction

LD-48R mud-pulse MWD was designed to meet various needs of hole-diameters, flow rates and other drilling requirements. The positive pulse system with less moving parts extends downhole life, simple maintenance and offers low resistance to flow ranges from 10 to 55Us. The downhole assembly is modular, which ensures easy handling and maintenance.

2.Surface Equipment

LD - MWD surface equipment mainly includes: Power Supply Box, Remote Data Processor, Pressure Transducer, and Computer that perform data reception, processing, display and so on. 

3.MWD System Technology Features

1.Positive mud pulse generator with high efficiency and low power consumption.

2.The modular structure design is more conducive to the assembling, testing and maintenance.

3.Downhole instrument automatically controls the working status and switches of energy saving mode.

4.Simple structure, the instrument adopts aviation plug flexible connection between subs.

5.The positions of general sub interface, directional, gamma are interchangeable.

6.Open instrument data bus is adopted, and easy to be upgraded and hooked up with other instrument.
