Abstract
Изобретение относится к области геофизических исследований параметров геологических пластов методом нейтрон-нейтронного каротажа. Техническим результатом изобретения является регистрация быстрых нейтронов, излучаемых импульсным источником нейтронов во время его импульсов, пропорциональным He-3 счетчиком при условии наложения электрических сигналов на выходе пропорционального счетчика, работающего в счетном режиме. Технический результат достигается тем, что пропорциональный He-3 счетчик подключен к усилителю-интегратору, усилитель-интегратор подключен к процессору, процессор подключен к системе телеметрии, при этом импульсный источник быстрых нейтронов подключен к блоку управления, блок управления подключен также к процессору.The invention relates to the field of geophysical studies of parameters of geological formations by neutron-neutron logging. The technical result of the invention is the registration of fast neutrons emitted by a pulsed neutron source during its pulses, proportional to the He-3 counter, subject to the superposition of electrical signals at the output of the proportional counter operating in the counting mode. The technical result is achieved by the fact that the proportional He-3 counter is connected to the integrator amplifier, the integrator amplifier is connected to the processor, the processor is connected to the telemetry system, and the pulsed fast neutron source is connected to the control unit, and the control unit is also connected to the processor.
