Product Introduction
SW-MWD wireless measurement while drilling system is developed by China's first batch of directional well experts. The R&D personnel are the makers as well as the users. Every design condensed their deep understanding of the spot, and each design has its independent intellectual property right. This product is reliable and durable with simple operation system, convenient maintenance and strong adaptability.
Suitable well conditions:
Wellbore diameter: 105~230mm
Displacement: 6~55L/s
Downhole temperature<125℃
Downhole pressure<120MPa
Features of MWD system:
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) Long durability, save time and effort: The maintenance interval of pulse and electromagnetic valve is over 500 hours, which is convenient for field use.
