На фиг. 1 и 2 изображены этапы установки патрубка в обсадной колонне.FIG. 1 and 2 depict the stages of installation of the pipe in the casing.
Способ осуш,ествл ют следуюш,им образом .The method of drying is as follows.
Трубы 1 и 2 с установленным на внут- ; ренней из них патрубком 3 устанавливают I концентрично (фиг. 1). Во внутрь патруб- ка 3 ввод т суженную часть расшир юш,его i конуса 4. Прикладывают к патрубку 3 осе- ; вое усилие, в результате чего деформирует- I с средн часть патрубка (фиг. 2). Пере- I ходные зоны 5 расточек 6 и проточек 7, заполненных герметизирующим покрытием, I деформиру сь, образуют на поверхности патрубка 3 выступы, взаимодействующие со стенкой обсадной трубы 1, и замкнутые по- I лости, заполненные герметизирующим мате- I риалом. В замкнутых полост х при этом образуетс давление и жесткость патрубка 3 повышаетс .

The constricted part is expanded into the inside of the pipe 3 and its i cone 4 is applied. Apply to the pipe 3, the axis 3; force, as a result of which it deforms - I with the middle part of the pipe (Fig. 2). The transition zones 5 of the bores 6 and the grooves 7 filled with a sealing coating, I deform, form on the surface of the pipe 3 protrusions interacting with the wall of the casing pipe 1 and closed cavities I filled with sealing material. In a closed cavity, this creates pressure and the rigidity of the pipe 3 increases. At the same time, these are closed; cavities formed by the contacting i with each other when the surfaces are closed; The bore 6 and the bore 7 and filled with elastic material change, rounded, the configuration of the sliding surface of the metal layers during deformation of the nozzle, contribute to the uniform distribution of stresses in the transition zones between the bores 6 and 7, preventing their destruction . After closing the contacting surfaces of the bores and grooves, the formation of closed cavities and protrusions under the action of an applied axial force, the expansion cone 4 is moved relative to the nozzle 3 and additionally deforms it in the radial direction, inserting the projections 5 into the wall of the obstruction pipe 1. Closed cavity 8 formed by the surfaces of the nozzle and the walls of the casing 1 are also further compacted.
