Description
Изобретение относитс к устройствам дл ремонта обсадных колонн вод ных , нефт ных и газовых скважин с целью восстановлени герметичности и из л ции проницаемых пластов в необсажен ных скважинах. Известен расширитель дл установки расшир емых хвостовиков в скважинах , содержащий штангу и размещенные на ней упругие секторы в виде цанги 1. . Недостатком указанного расширител вл етс невозможность его применени в скважинах с различными внутренними диаметрами без замены упругих сектеров . Известен расширитель дл установки расшир емых хвостовиков в скважинах , включающий штангу с размещенной на ней конической втулкой и упругими секторами, одним концом закрепленными на штанге L2 J. Недостатком указанного расширител вл етс большое количество деталей с трущимис поверхностйми в про .цессе расширени хвостовика, что может привести к заклиниванию перемещающихс деталей в результате по влени зазоров и засорени зазоров между ними. Цель изобретени - повышение надежности работы устройства путем уменьшени трущихс поверхностей в процессе расширени хвостовика. Указанна цель достигаето тем, что коническа втулка жестко св зана со штангой, а секторы на внутренней поверхности имеют выступы дл взаимодействи с конической поверхностью втулки-. На фиг. 1 схематично изображен предлагаемый расширитель дл установки расшир емых хвостовиков в скважинах; на г. 2 - разрез А-А на фиг.1. Расширитель имеет штангу 1, вы- полненную в верхйей части с поддерживающим хвостовик 2 конусным пуансоном 3, упором 4 и в нижней части сThe invention relates to devices for repairing casing strings of water, oil and gas wells in order to restore airtightness and from the repair of permeable formations in open hole wells. A known extender for installing expandable liners in wells, comprising a rod and resilient sectors placed on it in the form of collet 1.. The disadvantage of this extender is the impossibility of its use in wells with different internal diameters without replacing the elastic sectors. Known extender for installing expandable liners in wells, including a rod with a conical sleeve placed on it and elastic sectors fixed at the end of the rod L2 J. The disadvantage of this extender is a large number of parts with rubbing surfaces in the process of expansion of the shank that lead to seizure of moving parts as a result of the appearance of gaps and clogging of gaps between them. The purpose of the invention is to improve the reliability of the device by reducing the rubbing surfaces in the process of expanding the shank. This goal is achieved by the fact that the conical sleeve is rigidly connected to the rod, and the sectors on the inner surface have protrusions for interacting with the conical surface of the sleeve. FIG. Figure 1 shows schematically the proposed extender for installing expandable liners in wells; on r. 2 - section aa in figure 1. The expander has a rod 1, made in the upper part with a supporting shank 2 with a tapered punch 3, an emphasis 4 and in the lower part with
резьбой, подвижный конусный пуансон 5, взаимодействующий с упругими секторами 6, удерживаемыми кольцом.7 регулирующую коническую втулку 8, соединенную резьбой со штангой 1, возвратную .пружину 9 и гайку 10. Упругие секторы на внутренней поверхности имеют выступ 11 дл взаимодействи с конической поверхностью втуллси 8.-.10threaded, movable conical punch 5, which interacts with elastic sectors 6 held by a ring; 8 .-. 10
Расщиритель работает следующим образом .The scavenger works as follows.
Регулирующа коническа втулка 8 устанавливаетс в положение, соответствующее габаритному диаметру рас- 15 пиренных секторов, заданному диаметру кважины. При вт гивании расширител кв.остовик 2, поддерживаемый конусным пуансоном 3, нижний конец расшир емого хвостовика переводит расширитель JQ рабочее положение, перемеща вниз о упора 4 подвижный конический пуансон 5 с упругими секторами 6, которые раздвигаютс регулирующей конической втулкой 8, до заданного положени и 25 сжимают возвратную пружину 10. При этом контакт взаимодействующих поверхностей осуществл етс по выступу 11 секторов 6.The adjusting conic sleeve 8 is set to a position corresponding to the overall diameter of the split sectors, given the diameter of the well. When retracting the square spreader 2, supported by the tapered punch 3, the lower end of the expandable shank moves the JQ extender to the working position, moving down the stop 4, the movable conical punch 5 with elastic sectors 6, which move the regulating conical sleeve 8 to the desired position and 25, the return spring 10 is compressed. In this case, the contacting of the interacting surfaces is carried out along the protrusion 11 of the sectors 6.
Расширение хвостовика осуществл - зо етс последовательно поддерживающим конусным пуансоном 3, подвижным конусным пуансоном.5 и упругими секторами 6о После расширени всего хвостовика и выходаиз него расширител , воз- 35 вратна пружина 10 переводит расширитель в транспортное положение, возвраща подвижный конусньш пуансон 5 и упругие секторы вверх.The extension of the shank is performed by the sequentially supporting taper punch 3, the movable taper punch.5 and elastic sectors 6o. After the whole shank has been expanded and exited by the expander, the return spring 10 moves the expander to the transport position, returning the movable cone 5 and the elastic sectors up.
Использование предлагаемого расширител дл установки хвостовиков в скважинах позвол ет повысить надежность работы по ремонту скважин,.увеличить работоспособность устройства и исключить адарии при установке расщир е1увых хвостовиков.The use of the proposed extender for installing liners in wells allows to increase the reliability of work on the repair of wells, increase the efficiency of the device and eliminate adarii when installing extensions of liners.
