MWD Drliing Survey System

  Product Description   MWD Drilling Survey System     1. Application Scope of MWD   Apply to the real-time monitoring of the well trajectory during directional drilling or horizontal drilling in petroleum, geology, coal, water conservancy industries etc.     2. Product Features of MWD     1) No need to debug, easy to operate: Only need to know the size of drill collar and displacement to choose the matching short suspension section and pulser. There is no need to on-site commissioning.      2)Small diameter, strong signal: The outer diameter of the Instrument is only 45mm, which ensures a small flow resistance and a strong mud pulse signal.     3)Low maintenance costs: The auxiliary parts of the instrument only need some o-rings and centralizers, which are at low cost.      4)Less accessories, easy to maintain: Just need to pay attention to the replacement of seriously worn centralizers and O-rings.      5)Long durability, save time and effort:  The maintenance interval of pulse and electromagnetic valve is over 500 hours, which is convenient for field use.      3.
