Description
Устройство дл цементировани хвостовиков обсадных колони работает следующим образом.A device for cementing casing liners works as follows.
После ycTiibOBKn хвостовика 8 в заданном иптернале перед началом цементировани в скважину спускают два шара 12 и 13, причем первый (нижний) шар 12 меньшего диаметра находитс от второго (верхнего) uiapa 13 па рассто нии 2,5-3,5 м и шары соединены между собой тросом.After ycTiibOBKn of the shank 8 in the given ipternal, before starting cementing, two balls 12 and 13 are lowered into the well, the first (lower) ball 12 of smaller diameter being from the second (upper) uiapa 13 at a distance of 2.5-3.5 m and the balls are connected between a cable.
Шары спускают на кабеле 16. Их устанавливают так, чтобы первый находилс примерно на 0,5 м выше упорного гнезда 10 подвесной пробки 9.Balls down on the cable 16. They are installed so that the first was about 0.5 m above the stop socket 10 of the suspension tube 9.
После закачки буферной жидкости, цементного раствора « лромывочной жидкости 1 объеме бурильных труб с учетом зоны сме1цени ., систему подвески шаров опускают I- помоп|ью лебедки, первый шар 12 перекрывает циркул ционный канал, создавшимс давлением срезают шпильки 11, происходит разрыв проволоки 14 в ослабленном сечении 15 и подвесна пробка 9 вместе с шаром 12 движетс вниз до упорного стоп-кольца. При этом прокачивают объем, равный внутреннему объему хвостовика 8. После получени сигнала «Стоп второй шар 13 опускают до посадки на упорное гнездо 4 запорной втулки 3, создавшимс давлением срезают шпильки 6 и открываютс циркул ционные окна 5. Скважину промывают до окончани времени схватывани тампонажного раствора. Кабель 16 с верхним шаром 13 извлекают из скважины и отсоедин ют бурильные трубы 1 от хвостовика 8. На этом процесс цементировани заканчиваетс .After the buffer fluid is pumped, the cement mortar of the washing liquid 1 to the volume of drill pipes, taking into account the zone ratio. The ball suspension system is lowered by I-winch aid, the first ball 12 blocks the circulation channel, the pressure of the wire is cut off by the studs 11. the weakened section 15 and the suspension tube 9 together with the ball 12 moves down to the stop stop ring. A volume equal to the internal volume of the shank 8 is pumped. After receiving the stop signal, the second ball 13 is lowered until the stop sleeve 4 is seated on the stop slot 4, the pressure pins are cut off by the pressure sleeve 3, and the circulation holes are opened until the end of the cement setting time . The cable 16 with the upper ball 13 is removed from the well and the drill pipes 1 are disconnected from the shank 8. This completes the cementing process.
