Abstract
Использование: в нефтегазодобывающей промышленности дл герметизации усть скважины при нефтегазопро влени х. Сущность изобретени : устройство содержит катушку 3 с узлом герметизации 6 и фиксатором. Ниже катушки 3 размещен центратор 2, выполненный в виде втулки 7с двухконусной поверхностью и наружным буртиком 8, расположенным между фланцами 4 и 9. Узел герметизации выполнен в виде подъемного патрубка 10 с конусной муфтой 11 и катушки Зс ответной конусной частью. Предложены две различные конструкции фиксаторов: дл работы с АПР и при отсутствии на устье механизмов дл свинчивани труб. Дл герметизации усть скважины подъемный патрубок 1, с муфтой 11 навинчивают на колонну труб 11, убирают клиновую подвеску и при опускании ввод т конусную муфту 11 в конусную часть катушки 3. После этого фиксируют имеющимс фиксатором. 3 ил.Usage: in the oil and gas industry for sealing the wellhead during oil and gas occurrences. SUMMARY OF THE INVENTION: the device comprises a coil 3 with a sealing assembly 6 and a latch. Below the coil 3, a centralizer 2 is placed, made in the form of a sleeve 7 with a two-conical surface and an outer shoulder 8 located between the flanges 4 and 9. The sealing unit is made in the form of a lifting pipe 10 with a conical sleeve 11 and a coil Зс with a mating conical part. Two different designs of clamps are proposed: for working with APR and in the absence of mechanisms for screwing up pipes at the mouth. To seal the wellhead, the lifting pipe 1, with the sleeve 11, is screwed onto the pipe string 11, the wedge suspension is removed and, when lowering, the conical sleeve 11 is inserted into the conical part of the coil 3. After that, it is fixed with an existing lock. 3 ill.
