Measuring instrument Wireless MWD Product
Wireless MWD Product Introduction RSYQ-48
MWD: abbreviation of "measurement while drilling". Wireless while drilling measuring instrument can measure in time during the drilling process, that is, under the condition of non-stop drilling, the mud pulse generator sends the data measured by the downhole probe to the ground, and after collection and processing by the computer system, real-time well bore parameters and formation parameters are obtained.
Feature of product
1. Mud pulse generator can be directly exchanged with instruments of QDT, GE and domestic MWD manufacturers, saving users' secondary investment.
2. The whole MWD system adopts low power consumption design, and a single battery can work for 300 hours.
3. The maintenance-free period reaches more than 800 hours, and the maintenance cost is one third of the traditional MWD.
4. The mud analysis signal is twice that of the traditional MWD, ensuring stable transmission at a longer distance.

The MWD can measure the dip angle, azimuth angle, tool face angle and the natural gamma intensity of the formation in the process of drilling, so as to provide well bore parameters and formation evaluation data in time for the drilling of highly deviated wells and horizontal wells. The biggest advantage of MWD is that it can "see" what is happening in the well in real time, and only delay a few minutes from the bottom hole measurement parameters to the ground receiving data, so it can improve the decision-making process. This instrument is necessary for improving drilling speed and ensuring drilling quality in directional and horizontal wells.
