Description
Известны устройства дл изв.чечени из скважин, состо щие из гидрав тических домкратов и кожуха, раскрепл емого на трубах клинь ми. Однако такие устройства мало эффективны и .Borehole extraction devices are known, consisting of hydraulic jacks and a casing, fixed on pipes with wedges. However, such devices are not very effective and.
Предлагаемое устройство отличаетс от известных простотой конструкции захватной части и выполнено в виде штанги, установленной в трубе и, снабженной в нижней части фланцем. Сцепление устройства со стенками трубы обеспечиваетс заливкой бетона на фланец.The proposed device differs from the gripping part known for its simplicity of design and is made in the form of a rod mounted in a pipe and provided with a flange in its lower part. Coupling the device to the pipe walls is provided by pouring concrete onto the flange.
На чертеже показано предлагаемое устройство.The drawing shows the proposed device.
Наружное усилие на трубе создают домкратами и клинь ми. Внутреннее усилие в трубе создают при .помощи предлагаемого устройства,. Дл этого в конец обсадной трубы 1, выступающий из скважины, вставл ют патрубок 2 с приваренным фланцем 3, который дл жесткости раскреплен прутками 4. На фланец ло высоте патрубка заливают быстросхватывающийс бетон 5, который создает прочное сцепление с трубой. Носле затвердевани цемента домкратами захватывают патрубок за фланцы (5 и 7 и вытаскивают трубу.The external force on the pipe is created by jacks and wedges. The internal force in the pipe is created by the aid of the proposed device. To do this, the nozzle 2 with a welded flange 3 is inserted into the end of the casing 1 protruding from the well, which is stiffened with rods 4 for rigidity. After cement hardens with jacks, they seize the pipe by the flanges (5 and 7 and pull out the pipe.
Дл возможности промывки при вытаскивании трубы .примен ют штангу 8 ,ввернутую во фланец 3. Применение резиновой прокладки 9 между фланцами 5 и 7 исключает проникновение раствора во внутреннюю , полость патрубка.For the purpose of flushing when pulling out the pipe, a rod 8 is screwed into flange 3. The use of a rubber gasket 9 between flanges 5 and 7 prevents the solution from penetrating into the internal cavity of the nozzle.
Предметизобретени Subject matter
Устройство дл извлечени труб из скважины, отличающеес тем, что, с целью упрощени конструкции его захватной части, оно выполнено в виде штанги, на нижней части которой укреплен фланец, помещаемый в трубу, слунсащий дл удержани заливаемого сверху цементного раствора.A device for extracting pipes from a well, characterized in that, in order to simplify the design of its gripping part, it is made in the form of a rod, on the lower part of which a flange is placed and placed in a pipe that slides to hold the cement solution poured in from above.
