GeoGuide Measurement While Drilling - MWD

タイトルまたは説明

• Ability to adapt to different working conditions, suitable for deep well high temperature well construction.
• Totally compatible to similar MWDS/LWD System
• Complete Specification, there are four kinds of borehole specifications (6". 8-1/2", 12-/4", 17-1/2") to meet the demand of various drilling
• Down hole turbine generator power supply system, suitable for working long hours safe and reliable; Unique power supply system, to ensure that in the case of ustable power supply turbine generator dropping pipe work.
• Unique inter-module communication protocol design, can be easily extended gamma measurement module, integrated gamma probe design patent.
• Depth module configuration, the ground depth and interface unit is highly integrated, real-time data measurement points and the corresponding depth; gamma, resistivity and depth and other parameters simultaneously and accurately determine the stratigraphic.
• Driller display is color display, Bright Light and dial the data show a clear compatible comprehensive logging acquisition system integraton engineering geology
