Description

йОстью патрубка 3 и внутренней поверхностью корпуса 1 и далее через окна 7 в нижней части патрубка 3 попадает в нижнюю полость Б корпуса 1.The branch pipe 3 and the inner surface of the housing 1 and then through the windows 7 in the lower part of the pipe 3 enters the lower cavity B of the housing 1.

Аналогично прокачиваетс  цементный раствор. После окончани  закачивани  цементного раствора открепл ют стопоры 5 и патрубок 3 вместе с цементированной пробкой 4 под .собственным весом опускаютс  вниз до посадочного по ска 2 корпуса 1. После посадки раструба 6 патрубка 3 на посадочный по сок 2 происходит перекрытне кольцевого пространства между патрубком и внутренней поверхностьго корпуса 1.Similarly, the cement slurry is pumped. After the injection of cement mortar is completed, the stoppers 5 are detached and the nozzle 3 together with the cemented plug 4 under their own weight are lowered down to the landing surface 2 of the body 1. After the socket 6 has landed, the nozzle 3 on the landing juice 2 closes off the annular space between the nozzle and the inner surface of the housing 1.

При прокачивании продавочной жидкости в верхнюю полость А корпуса 1 цементировочна  пробка выталкиваетс  вниз и начинает двигатьс  по обсадной колонне. После посадки цементировочной пробки на упорное кольцо, о чем свидетельствует резкое повышение давлени  на цементировочных агрегатах процесс цементировани  прекращают .When pumping the squeeze fluid into the upper cavity A of body 1, the cement plug is pushed down and begins to move along the casing. After the cementing plug is seated on the stop ring, as indicated by a sharp increase in pressure on the cementing units, the cementing process is stopped.

При всех этих операци х производ т расхаживание или вращение обсадочной колонны в зависимости от состо ни  ствола скважины и технологических особенностей креплени  скважины.In all these operations, the casing is rotated or rotated, depending on the state of the well bore and the technological features of the well casing.
