Description
При производстве буровых работ с обсадными трубами, возникает необходимость извлечь из скважины ранее опущенную колонну труб. Примен емые в насто щее врем способы извлечени колонн труб трудоемкий основаны навырезывании колонны по част м или на выт гивании домкратами, на что затрачиваетс много времени.In the production of drilling with casing, there is a need to extract from the well previously lowered string of pipes. The currently used methods for removing pipe columns are laborious, based on cutting up the column in parts or on jacking, which takes a lot of time.
Особенностью иасто щего изобретени вл етс применение при извлечении обсадных труб любых диаметров ударно-вибрационного т гового ycTpoviCTBa, которое легко может быть смонтировано при надобности на любой бурово вытике.A special feature of the present invention is the use in removing casing pipes of any diameters of a shock-vibration traction ycTpoviCTBa, which can be easily mounted if necessary on any drilling tool.
На чертеже изображена схема устройства дл осуществлени способа .The drawing shows a diagram of an apparatus for carrying out the method.
Ударно-вибрационное устройствоShock vibration device
состоит па перевернутого свайного молота 1 двойного действи .consists of an inverted pile hammer 1 double action.
Свайный молот двойного действи подвеи1иваетс на канатах :J и крюке 5 и своими короткими и б|1|стрыми ударами вызывает вибрацию колонны труб 4, чем наруишет заи1,емление трубы породой. Расшатанную свайным молотом колонну обсадных труб легче извлечь .A double-action pile hammer is driven on the ropes: J and hook 5, and with its short and short blows it causes vibration of the string of pipe 4, which will disturb the replacement of the pipe with rock. A column of casing shattered with a pile hammer is easier to remove.
Предмет изобретени Subject invention
Способ извлечени незацементпрованных обсадных колонн из .мелких скважин, отличающийс тем, что, с целью освобождени труб от прихвата породой, обсадную колонну выбивают подвешенным над устьем скважины свайным молотом (иаровым или внутреннего сгорани ), монтируемым в перевернутом положении.A method of extracting uncemented casing from small wells, characterized in that, in order to free the pipes from sticking with the rock, the casing is knocked out by a pile hammer suspended (suspended in a vertical or internal combustion) mounted over the wellhead.
