China Wireless Mud Pulse MWD
Product Description
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. We provide three series of mud pulse MWD as below: LK301 Magnetic coupling 125℃ LK401 Magnetic coupling 150℃ LK501 Connector assembly 175℃ 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. Packaging & Shipping
