Epidemic Prevention Materials

  • Compensated Neutron Logging Tool
  • Brief Introduction:

  • CNLT uses fast neutrons produced by isotopic neutron sources, which decay into thermal neutrons after multiple scattering of formation materials. The thermal neutron intensity is closely related to the hydrogen content in the formation.

  • Lithology Density Logging Tool
  • Brief Introduction:

  • LDLT uses Cs137 gamma source to emit gamma rays, uses Compton scattering to measure formation volume density, calculates formation porosity, and uses photoelectric absorption index Pe to closely relate to atomic number of matter to divide lithology.

  • Compensated Density Logging Tool
  • Brief Introduction:

  • CDL uses Cs137 gamma source to emit gamma rays with energy of 0.662MeV, and Compton scattering is used to measure formation volume density.

  • Stratigraphic Dipmeter Tool
  • Brief Introduction:

  • SSDT is used to detect the spatial position of formation interface in open hole wells. Based on the geometric principle of one side determined by three points，the difference of depth of the same stratum layer is measured.

  • Tension,Borehole Temperature and Mud Resistivity Sub
  • Brief Introduction:

  • TTMR provides cable head tension, current borehole temperature, and drilling fluid resistivity. The cartridge consists of a sonde assembly and an electronics section.

  • Telemetry Cartridge
  • Brief Introduction:

  • TELC collects the data of each downhole tool through CAN bus, and transmits it to the surface system by cable through encoding, modulation, DA conversion and drive.
