Drilling equipment MWD Measurement While Drilling
Introduction: Measurement While Drilling
This is a Bottom-Mounted & Retrievable Positive Mud Pulse MWD, which can be dropped at the
top of the well and retrievable from the bottom of the well, and has accurate measurement and
convenient usage. The instrument uses mature and reliable positive mud pulse technology and
transmits stand pipe signals and other parameters by radio on the ground. When using, it does not
need to lay out cables. Patents ZL 200920110229.5, ZL 201020121771.3, ZL 200820133003. 2, ZL
