is designed for definition the oil-and-gas saturation of reservoir beds in the small hole wells by nuclear methods of INNGK/ INGK, INGKS-GIRZ, NAK, SGK.
Features and advantages
• it completes measurement of the lifetime thermal neutrons (2INNK/2INGK), and spectrometry capture gamma-rays of thermal neutrons (of spectrum GIRZ);
• application of the tool in conjunction with (SGK) natural gamma ray spectrometry, TzSP-GC-S-76 allows to record the parameters of (NAC) neutron activation logging and natural gamma ray spectrometry with the registration of radioactive elements U, Th, K;
• the tool can be used in slim hole wells, including the shanks and lateral holes.
The tool works with pulsed neutron generator ING-10-20-120/150, it is run with the log recorder Volcano V3, with tree-core cable.
