PERFORMED THROUGH THE PRODUCTION STRING NEUTRON MEASUREMENT, DEVICE, SYSTEM FOR ITS IMPLEMENTATION AND THEIR APPLICATION Russian patent published in 2018 - IPC E21B49/00 G01V5/14 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the formation properties measurements performance systems, devices and methods. Method comprises the neutron field emission into formation from the neutrons source, acquisition of data, including the neutron-neutron method (LNN) long-range data, neutron-neutron (SNN) near data, neutron gamma method (LNG) long-range data and neutron gamma method (SNG) near data, based on the emitted into the formation neutron field, long-range data combination with short data to reduce associated with the evaluated characteristic error. At that, the evaluated characteristic is the neutron porosity (QTP). Wherein, the said QTP characteristic is evaluated by the mathematical formula.

EFFECT: technical result is increase in the formation parameters determination efficiency.
