Product Description

MWD LWD Measure While Drilling

 

The MWD adopts mature and reliable positive mud pulse technology. It transmits stand pipe signals
and other data by radio on the ground. There is no need to lay out cables, which make it easy and
convenient for operation.
The mud pulse MWD adopts Bus technology. Natural gamma and Azimuth gamma are optional, and
then Depth system should also be used cooperatively to expand application range of the MWD.
 
 
Working Principle
The Pulser acquires related down-hole data, and the acquired data is encoded into certain series
data string via control unit. The data string controls the movement of electromagnetic valve, and the
circulating mud makes the main valve poppet move synchronously, thus, mud flow area between
the poppet and block ring is controlled. When the poppet is up, the mud in drill string passes
through the block ring smoothly; when the poppet is down, mud flow area reduces, and then a
positive mud pressure pulse is generated inside the drill string.
The pressure sensor on the mud pipeline acquires mud pressure signal with certain frequency and
transmits the signal wirelessly. Wireless transceiver connected with PC receives and
processes the pump pressure signal. The signal is decoded into data by DEES software and the
results are transmitted to driller's display wirelessly.
