Description
При подъеме и спуске насосно-компрессорных труб 14 последние прох-од т через отверстие эластичного уплотнени 5. При поперечном осевом смещении извлекаемых или опускаемых труб соответствующее смещение , передаваемое через уплотнение 5, сообщаетс муфте 4, котора перемещаетс в камере 2, при этом кра юбки 6 скольз т по плоскост м корпуса 1 и крыщки 8, обеспечива герметизацию муфты 4. При проходе соединительной муфты 15 уплотнение 5 раст гиваетс на диаметр муфты 15, герметично пропускает ее и вновь уплотн етс по трубе 14. При вращательном движении труб 14 муфта 4 вращаетс вместе с трубой . При спуске труб в воронку 13 заливаетс жидкость дл смазки труб 14, этим достигаетс снижение износа уплотнени 5.When lifting and lowering the tubing 14, the latter passes through the orifice of the elastic seal 5. With the transverse axial displacement of the extracted or lowered tubes, the corresponding displacement transmitted through the seal 5 is coupled to the coupling 4, which moves in the chamber 2, while the skirt 6 slides along the planes of the housing 1 and the lid 8, sealing the coupling 4. When the coupling 15 passes, the seal 5 is stretched to the diameter of the coupling 15, passes it tightly and re-seals through the pipe 14. With rotational movement enii pipe coupling 14 4 rotates together with the pipe. When the pipes are pushed into the funnel 13, liquid is poured in to lubricate the pipes 14, thereby reducing wear on the seal 5.
Изобретение обеспечивает надежность герметизации усть скважины и снижает веро тность аварии при спуско-подъемных операци х с насосно-компрессорными трубами .The invention provides reliable sealing of the wellhead and reduces the likelihood of an accident during tripping operations with tubing.
