The 200°C HT MWD System is a core measurement and control device specificallydesigned for directional drilling in deep and ultra-deep HTHP oil and gas wells, as wellas HT geothermal wells. By integrating key technologies of ultra-HT wide-tempera-ture-range adaptation, erosion-resistant stable transmission, long-endurance HTpower supply, and highly reliable anti-vibration integration, it can continuously deliv-er real-time, accurate and stable downhole engineering and environmental parame-ters in extreme downhole conditions of 200°C and 30kpsi. It is compatible with vari-ous complex drilling conditions and provides end-to-end core technical support forprecise trajectory control and safe, efficient operations in deep drilling.
Ø Using HT-resistant components, special insulating materials, and efficientthermal management system, the system can operate stably in wide tem-perature range of -40 to 200°C and under high-pressure conditions up to30kpsi
Ø With upgraded erosion-resistant and wear-resistant structure for the pulsegenerator, it supports adjustable multi-level transmission rates from 0.2 to1bit/s
Ø With low-power design and intelligent power management technology, thecontinuous operating time under typical conditions is >200h
Ø With integrated structure and multi-stage shock absorption layout, it canwithstand strong vibration of 20g RMS and strong shock of 1000g@0.5ms,making it suitable for complex drilling conditions
