(54) РАСШИРИТЕЛЬ(54) EXTENDER

1one

Изобретение относитс  к креплению скважин и используетс  при изол ции проницаемых пластов в необсаженных скважинах и ремонте обсадных колонн.The invention relates to the fastening of wells and is used in isolating permeable formations in open casing and repairing casing strings.

Известен расширитель дл  установки расшир емыххвостовиков в скважинах, содержащий штангу с коническим элементом и опираюш,имис  на него секторами 1.Known extender for installing expandable tailings in wells, containing a rod with a conical element and supports it with sectors 1.

Недостатком этого расширител   вл етс  необход11мость точного измерени  внутреннего диаметра обсадной колонны в месте ремонта дл  установки регулирующей конической втулки, так как допуск на изготовление обсадных труб значительно превышает упругий прогиб секторов. Неточность измерени  приводит k неправильной установке регулирующей конической втулки, что вызывает неплотное прилегание расшир емого хвостовика к стенке обсадной колонны или поломку секторов.The disadvantage of this expander is that it is necessary to accurately measure the internal diameter of the casing string at the repair site to install a regulating conical sleeve, since the tolerance for the production of casing pipes considerably exceeds the elastic deflection of the sectors. Inaccuracy of measurement leads to incorrect installation of the regulating conical sleeve, which causes a loose fitting of the expandable shaft to the wall of the casing or breakdown of the sectors.

Наиболее близким к предлагаемому по технической сущности и достигаемому результату  вл етс  расширитель дл  установки расшир емых хвостовиков в скважинах, включающий штангу с подвижным конусным пуансоном, секторы, опорный элемент и выступы ,2.Closest to the proposed technical essence and the achieved result is an expander for installing expandable liners in wells, including a rod with a movable conical punch, sectors, support element and protrusions, 2.

Недостатком этого устройства  вл етс  возможность заклинивани  при встрече меньшего внутреннего диаметра обсадной колонны .A disadvantage of this device is the possibility of jamming when a smaller inner diameter of the casing is encountered.

Цель изобретени  - повышение надежности работы расширител  путем уменьшени  возможности заклинивани .The purpose of the invention is to increase the reliability of the expander by reducing the possibility of seizure.

Указанна  цель достигаетс  тем, что в расширит,еле, включающем штангу с подвижным конусным пуансоном, секторы, взаимодействующие с опорным элементом, и выступы , опорный элемент жестко закреплен на This goal is achieved by the fact that in expanding, barely including a rod with a movable conical punch, sectors interacting with the supporting element and protrusions, the supporting element is rigidly fixed to

10 конусном пуансоне, а выступы - на опорном элементе, установленном с возможностью взаимодействи  выступов с секторами.10 conical punch, and the protrusions - on the support element, installed with the ability to interact protrusions with sectors.

На фиг. 1 изображен расширитель дл  установки расшир емых хвостовиков в сква ,5 жинах, обший вид; на фиг. 2 - транспортное положение расширител ; на фиг. 3 - разрез А-А на фиг. 2; на фиг. 4 - разрез Б-Б на фиг. 1.FIG. 1 shows an expander for installing expandable shanks in a well, 5 wires, a general view; in fig. 2 - transport position of the expander; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. one.

Расширитель имеет штангу 1, выполненную в верхней части с поддерживающим хвостовиком 2 конусным пуансоном 3, а в The expander has a rod 1, made in the upper part with a supporting shank 2 with a tapered punch 3, and in

20 нижней части - с резьбой, подвижный конусный пуансон 4, имеюший выступы 5, взаимодействующие с упругими секторами 6, опирающимис  на гайку 7 и удерживаемыми разрезным кольцом 8, возвратную пружину 9, упирающуюс  в гайку 10, упор II, ограничивающий расхождение секторов.The bottom part 20 is threaded, a movable tapered punch 4 having projections 5 interacting with elastic sectors 6 supported on nut 7 and held by a split ring 8, return spring 9 abutting nut 10, stop II, limiting the divergence of sectors.

Расщиритель работает следующим образом .The scavenger works as follows.

При вт гивании расширител  в хвостовик 2 (фиг. 1) поддерживаемый конусным пуансоном 3 нижний торец расшир емого хвостовика , перемеща  подвижный конусный пуансон с выступами 5, переводит расширитель в рабочее положение, раздвига  секторы 6 до упора в стенку обсадной колонны 12 и сжима  возвратную пружину 9.When the reamer is pulled into the shank 2 (Fig. 1), the lower end of the expandable shank supported by the conical punch 3, moving the movable conical punch with the projections 5, moves the expander to the working position, pushing the sectors 6 all the way into the wall of the casing 12 and compressing the return spring 9.

Расширение хвостовика осуществл етс  последовательно поддерживающим конусным пуансоном 3, подвижным конусным пуансоном 4 и упругими секторами 6. После расширени  всего хвостовика и выхода из него расширител  возвратна  пружина 9 переводит расширитель в транспортное положение (фиг. 2), возвраща  подвижный конусный пуансон 4 и упругие секторы 6 в первоначальное положение.The extension of the shank is carried out sequentially by supporting the conical punch 3, the movable conical punch 4 and the elastic sectors 6. After the entire shank is expanded and exited by the extender, the return spring 9 converts the expander into the transport position (Fig. 2), returning the movable cone 4 and elastic sectors 6 in the original position.

При расщирении хвостовика в необсаженной скважине необходимо упор 11 установить в положение, соответствующее требуемому диаметру расширени  хвостовика.When extending the shank in an open hole, it is necessary to place the stop 11 in a position corresponding to the required diameter of the expansion of the shank.

Использование предлагаемого расширител  дл  установки хвостовиков в скважинах позвол ет исключить необходимость измерени  внутреннего диаметра обсадной колонны перед ремонтом, повысить надежность работы при установке расшир емых хвостовиков .The use of the proposed extender for installing liners in wells eliminates the need to measure the internal diameter of the casing before repair, and to increase the reliability of operation when installing expandable liners.
