Изобретенне относитс к области нромыслово-геофизнческих исследований скважин.The invention relates to the field of field and geophysical well studies.
Известно устройство дл нрнсоедннени каротажного кабел к скважинным приборам, содержащее накидную гайку, личинку дл креплени брони кабел , колодку и вилку штенсельного разъема.A device for the practical integration of a logging cable to downhole tools is known, comprising a cap nut, a larva for fastening the cable armor, a shoe and a plug of a plug connector.
Недостатками известного устройства вл ютс сложность конструкции, плоха изол ци , неудобство эксилуатации и недостаточна герметизаци , что приводит к снижению надежности и срока службы.The disadvantages of the known device are the complexity of the design, poor insulation, inconvenience of force and insufficient sealing, which leads to a decrease in reliability and service life.
Предлагаемое устройство отличаетс от известного тем, что личинка снабжена полой цилиндрической втулкой с уплотнительным кольцом, в полости которой размещена колодка разъема. Это позвол ет повысить надежность герметичной полумуфты.The proposed device differs from the known one in that the larva is provided with a hollow cylindrical bushing with a sealing ring, in the cavity of which a connector block is placed. This makes it possible to increase the reliability of the hermetic coupling half.
На чертеже показана описываема герметична полумуфта.The drawing shows described hermetic half coupling.
Дл соединени полумуфты с головкой скважинного прибора служит накидна гайка 1, надета на личинку 2. Личинка содержит полую цилиндрическую втулку 3 с окнами 4, на которой установлены уплотнительное кольцо 5 и колодка 6 щтепсельного разъема. В корпусе 7 головки скважинного прибора имеетс цилиндрическа полость, в которой на.ходитс ;вилка 8 штепсельного разъема.To connect the half coupling to the head of the downhole tool, there is a cap nut 1, put on the larva 2. The larva contains a hollow cylindrical sleeve 3 with windows 4, on which a sealing ring 5 and a plug 6 of the plug connector are mounted. In the housing 7 of the head of the downhole tool there is a cylindrical cavity in which a plug 8 of the plug connector is located.
Каротажный кабель подсоедин етс к герметичной полумуфте следующим образом.The logging cable is connected to the hermetic coupling half as follows.
Кабель 9 пропускают через накидную гайку 1 и личинку 2. Броню кабел закренл ют в личинке, а его жилы про.ход т внутри полой цилиндрической втулки 3 и через окна 4 распаиваютс к электродам колодки 6 разъема. После распайки жил внутреннюю полость uiлиндрической втулки заливают через окна электроизол ционным комлаундом.The cable 9 is passed through the cap nut 1 and the larva 2. The cable armor is closed in the larva, and its cores pass through the hollow cylindrical sleeve 3 and through the windows 4 are unsoldered to the electrodes of the connector block 6. After soldering the cores, the internal cavity of the cylindrical sleeve is poured through the windows with an electrical insulation shell.
При навинчивании накидной гайки на корпус головки скважинного прибора происходит сочленение вилки 8 с колодкой 6 разъема. Дл взаимной фиксации частей разъема на вилке имеетс выступ, который входит в паз колодки разъема. Герметизаци полумуфты осуществл етс при помощи резинового унлотнительного кольца 5 и электроизол ционного компаунда в полости втулки.When screwing the cap nut onto the casing of the head of the downhole tool, the coupling of the plug 8 with the connector block 6 occurs. For interlocking the connector parts, there is a protrusion on the plug that fits into the groove of the connector pad. The sealing of the coupling half is carried out with the help of a rubber sealing ring 5 and an electrical insulating compound in the cavity of the sleeve.
Предмет изобретени Subject invention
Герметична полумуфта дл присоедикени каротажного кабел к скважинным приборам , содержаща накидную гайку, личинку дл креплени брони кабел , колодку и вилку щтепсельного разъема, отличающа с тем, что, с целью ловыщени надежности, личинка снабжена полой цилиндрической втулкой с уплотнительным кольцом, в полости которой размещена колодка разъема.A sealed coupling half for attaching the logging cable to downhole tools, comprising a cap nut, a larva for securing armor of the cable, a shoe and a plug connector, characterized in that, in order to increase reliability, the larva is provided with a hollow cylindrical sleeve with an O-ring, in which there is a cavity in the cavity. connector block.
