Изобретение отнсситс к устройствам дл рем 1нта обсадных колонн вод ных, нефт ных и газовых скважин с целью восстановлени герметичности или упрочнени стенок колонны при помощи продольно-гофрированной металлической трубы.
Известна гидравлическа дорнируюша головка, содержаща подвижные стопоры, диафрагму и металлические пластины
Недостатком такой дорнируюшей головки вл етс то, что в ней не предусмотрена защита от выдавливани материала упругой диафрагмы в зазоры между подвижными секторами.
Наиболее близкой к изобретению вл етс гидравлическа дорнирующа головка , включающа подвижные секторы, размещенные на упругой трубчатой диафрагме , и металлические пластины, присоединенные к внутренней поверхности секторов 2 .
Недостатком этой дорнируюшей головки вл етс ее ненадежность в работе ввиду отсутстви защиты против зате-
кани материала диафрагмы в зазоры по кра м пластин. Кроме того, жесткое крепление пластин приводит к тому, что при наклоне секторов осевое усилие дорнировани передаетс на пластины, что приводит к их поломке или нарушению креплени .
Цель изобретени - повышение надежности головки в работе за счет предотвращени затекани материала диафрагмы в зазоры по кра м пластин.
Указанна цель достигаетс тем, что между пластинами и диафрагмой установлены вьгступаюшиес за кра пластин проладки , а пластины присоединены к секторам с возможностью смешени , причем прокладки выполнены из плотной ткани, например брезента.
Claims (2)
- На фиг. 1 иаобрбцкена дорнирующал головка в транспортном положении, продольный разрез; на фиг. 2 - сечение А-А фиг. 1; на фиг. 3 - то же в момент создани избыточного давлени в устройстве; на фиг. 4 - сечение Б-Б фиг, 3. Дорнирующа головка имеет полую перфорированную штангу 1, на которой между фланцами 2 установлена упруга трубчата диафрагма 3 с размещенными на ней подвижными секторами 4, К опор ной поверхности каждого второго сектора с помощью винтов 5 присоединены металлические пластины 6, причем в пластинах отверсти под винты выполнены с зазором, достаточным дл самоустановки пластин относительно опорной поверхности при любых возможных положени х секторов , а по ширине пластины выступают за боковые кра секторов на величину, боль шую, чем максимально возможный боково зазор между секторами, К пластинам со стброны диафрагмы присоединены проклад ки 7 из плотной ткани, например брезента , так, что кра ткани выступают за кра пластин 6. В ремонтируемой обсадкой колонне 8 установлен пластырь 9. Устройство работает следующим образом . . При создании давлени в устройстве трубчата диафрагма 3 расшир етс и раздвигает секторы 4 до упора в расточки фланцев 2. При этом образующийс между секторами 4 боковой зазор перекрываетс выступающими част ми пластин 6, которые прижимаютс диафрагмой к опорным поверхност м смежных секторов, а кра прокладок 7 подгибаютс ; закрыва оставшиес зазоры по кра м пластин 6, При заходе (или выходе ) головки в пластырь 9 секторы 4 нак лон ютс по отношению к оси головки, В Эти моменты пластины 6 смещаютс k 5 б 7 л V %%%% %%%%% вдоль секторов 4, самоустанавлива сь по отношению к опорной поверхности, и поэтому осева нагрузка дорнировани не передаетс через торцы пластин. Все это повышает надежность дорнирующей головки . Формула изобретени 1 Гидравлическа Дорнирующа головка дл распрессовки пластырей при ремонте обсадных колонн, включающа подвижные секторы, размещенные на упругой трубчатой диафрагме, и металлические пластины, присоединенные к внутренней поверхности секторов, отличающа с тем, что, с целью повышени надежности головки в работе за счет предотвращени затекани материала диафрагмы в зазоры по кра м пластин, между пластинами и диафрагмой установлены выступающие за кра пластин прокладки , а пластины присоединены к секторам с возможностью смещени . 2, Гидравлическа дорнирукша головка по п. 1, отличающа с тем, что прокладки выполнены из плотной ткани, например брезента.
