(54) УСТРОЙСТВО ДЛЯ ИЗВЛЕЧЕНИЯ КАБЕЛЯ ИЗ СКВАЖИНЫ(54) DEVICE FOR EXTRACTING THE CABLE FROM THE WELL
1one
Изобретение относитс к области бурени нефт ных и газовых скважин и предназначено дл ликвидации прихватов каротажного кабел в скважине.The invention relates to the field of drilling oil and gas wells and is intended to eliminate the sticking of the logging cable in the well.
Известно устройство дл освобождени прихваченного в скважине прибора с кабе- 5 лем, состо щее из корпуса, выполненного из двух концентрично расположенных труб с продольными пазами, переводника и свободно вращающегос стержн , жестко соединенного с корпусом 1.,QA device is known for releasing a device with a cable that is stuck in a well, consisting of a body made of two concentrically arranged pipes with longitudinal grooves, a sub and a freely rotating rod rigidly connected to body 1., Q
Недостатком этого устройства вл етс невозможность отрезани кабел над прихваченным прибором.A disadvantage of this device is the impossibility of cutting the cable over a stuck device.
Наиболее близкой к предложенному по технической сущности вл етс ловушка дл освобождени каротажного кабел , спуска- 15 ема в скважину на колонне бурильных труб, содержащща корпус с порщнем и механизм среза кабел 2.Closest to the proposed technical entity is a trap for releasing the logging cable, which is lowered into the well on the string of drill pipe, containing a housing with a piston and a shear mechanism for the cable 2.
В этом устройстве кабель пропускаетс через ловущку с эксцентричным отверстием, 20 присоединенную к бурильной колонне труб. При спуске устройства в скважину кабель находитс между колонной труб и стенкой скважины, что может приводить к заклинкеIn this device, a cable is passed through a trap with an eccentric hole 20 connected to the drill string of pipes. When the device is lowered into the well, the cable is located between the pipe string and the wall of the well, which can lead to jamming
кабел колонной труб и его прихвату в местах с большим градиентом кривизны ствола скважины. Кроме того, освобождение кабел в колоннал бурильных труб этим устройст вом невозможно, а ликвидаци прихвата кабел в открытом стволе скважины требует много времени.cable pipe string and its sticking in places with a large gradient of curvature of the wellbore. In addition, the release of the cable into the drill string by this device is impossible, and the elimination of sticking of the cable in the open borehole takes a lot of time.
Цель изобретени - повышение эффективности работы устройства за счет автономного спуска его в скважину по кабелю и подъема вместе с обрезанным кабелем.The purpose of the invention is to increase the efficiency of the device due to its autonomous descent into the well through the cable and lifting along with the cut cable.
Указанна цель достигаетс тем, что устройство снабжено механизмом зажима устройства на кабеле и системой блоков, образующих стрелу прогиба кабел , причем подвижный блок расположен на рычаге, один конец которого шарнирно закреплен на оси верхнего неподвижного блока. Корпус выполнен с каналом, св зывающим пространство над порщнем со скважинным, причем в канале установлен клапан, св занный гибкой т гой с другим концом рычага, поршень имеет шток с конусным наконечником.This goal is achieved by the fact that the device is equipped with a device clamping mechanism on the cable and a system of blocks that form a cable deflection boom, the movable block being located on the lever, one end of which is pivotally fixed on the axis of the upper fixed block. The housing is made with a channel that connects the space above the rock with the well, and the valve is connected to the channel connected by a flexible rod to the other end of the lever, the piston has a rod with a tapered tip.
