Description

В известных подобных приборах при изменении величины зонда (рассто ни  между нейтронным источником и индикатором) необходимо поднимать снар д из скважины. Операци  подъема снар да, его разборки, установки нужного рассто ни , сборки и спуска в скважипу вызывают значительное сниже гие производительности. При этом обслуживающий персоиал попадает в зону опасного дл  здоровь  интенсивного облучени  пейтронами.In known similar devices, when the magnitude of the probe changes (the distance between the neutron source and the indicator), it is necessary to lift the projectile out of the well. The operation of lifting the projectile, disassembling it, setting the desired distance, assembling and launching into a well causes a significant decrease in productivity. At the same time, the serving personnel gets into the zone of intensive exposure to peyron radiation.

Предлагаемое устройство устран ет указанные недостатки, так как с его помощью операцию по перемещению источника можно производить без подъема снар да на поверхность.The proposed device eliminates these drawbacks, since with its help the operation of moving the source can be carried out without lifting the projectile to the surface.

На фиг. 1 схематически показано устройство; на фнг. 2-электрическа  схема управлепи  движением источника в корпусе.FIG. 1 shows a schematic of the device; on fng. 2-electrical control circuit of the source in the housing.

Части / и 2 разъемного корпуса сн р да соединены муфтой 3 с герметическим уплотнением 4. В части / корпуса помещены усилитель 6 и высоковольтный генератор с температурным компенсатором 7, индикатор 8 гамма-лучей и свинцовый экран 9. В части 2 корпуса помещаютс  источник 10 быстрых нейтронов и механизм 11 с дистанционным управлением дл  перемещени  источника 10 на заданное от индикатора 6 рассто ние.Parts / and 2 split housings are connected by a coupling 3 with a hermetic seal 4. Amplifier 6 and a high-voltage generator with a temperature compensator 7, an indicator 8 of gamma rays and a lead shield 9 are placed in the part / case. neutrons and a remote control mechanism 11 for moving the source 10 a distance specified from the indicator 6.

Дл  осуществлени  передвижени  источника 10 на заданное рассто ние обмотка 12 электродвигател  механизма перемещени  источника посредством реле 13, включенного в цепь скважинпого снар да, присоедин етс  с помощью контакта 14 к проводу А. Электродвигатель при своем вращении измен ет полон ение источника 10 и одновременно перемещает ползун реостатного датчика ,. При этом измен етс  ток в цепи электроизмерительного прибора 5. По величине отклонени  стрелки последнего суд т о положении источника JO нейтронов.In order to move the source 10 for a predetermined distance, the winding 12 of the motor of the source moving mechanism by means of a relay 13 connected to the wellbore circuit is connected by means of contact 14 to the wire A. The motor changes the position of the source 10 while rotating rheostat sensor,. In this case, the current in the circuit of the electrical measuring device 5 changes. According to the magnitude of the deviation of the arrow of the latter, the position of the neutron source JO is judged.
