    • Near-bit Geosteering Drilling System (CGDS)

    • The CGDS Near-bit Geosteering Drilling Systemintegrates the drilling technology, logging technology and reservoir engineering technology as one, uses the near-bit geology, engineering parameter measurement and CWD measures to guarantee the actual wellbore to penetrate the reservoir and get the best position, adjusts and controls the well track in real time based on formation characteristics information measured by MWD to ensure the bit advances along with the oil layer, it has the characteristics of identifying hydrocarbon reservoir while drilling and strong guiding function.
