NET-ORIENTED HYDRAULIC ACTIVATION SUB, NHAS

It uses the hydraulic mechanical principle to push combined logging sonde of spectro density and micro-spherically focused logging to the side wall, measure the formation parameters correctly, and provide the caliper logging data.

DENSITY SONDE AND MICRO-SPHERICAL FOCUSED SONDE, SDMF

The Litho-Density tool uses a gamma source (1.5Ci, Cs137) and two detectors of different spacing to contact the sidewall directly. Based on Photoelectric Effect and Compton Effect, corresponding energy windows are set up, recording the gamma ray of various windows, and measuring the lithology and density of formation.

MULTICHANNEL GR SPECTROSCOPY TOOL, MGST

When a gamma ray enters into the NaI crystal, the photo multiplier outputs a pulse with amplitude proportional to gamma ray energy absorbed by NaI crystal. It adopts spectrum stabilization technology to set up windows with different energies. The counting rate of each energy window is sent to the surface system by electronic circuits. After processed by surface system, Th, U and K contents are calculated out.
