Description
Изобретение относитс к горной промышленности, в частности к устьевому оборудованию эксплуатационных скважин.The invention relates to the mining industry, in particular, to wellhead equipment of production wells.
Цель изобретени - повышение надежности работы устройства при перерезании кабел в случае аварийного падени скважинного оборудовани .The purpose of the invention is to improve the reliability of the device when cutting the cable in the event of an accidental fall of downhole equipment.
На фиг.1 изображено устройство, продольный разрез; на фиг.2 - разрез А-А на фиг.1; на фиг.З - схема установки устройства на устье скважины.Figure 1 shows the device, a longitudinal section; figure 2 - section aa in figure 1; Fig. 3 is a diagram of the installation of the device at the wellhead.
Устройство состоит из корпуса в виде жестко св занных между собой стоек 1, верхней 2 и нижней 3 плит с осевыми каналами под кабель 4. В верхней плите 2 имеетс узел 5 герметизации кабел 4. Верхн плита 2 жестко св зана с кожухом 6, который соединен с промежуточной катушкой 7, установленной на устье 8 скважины под планшайбой 9 с прикрепленной к ней колонной 10 насосно-компрессорны труб. На стойках 1 шарнирно на ос х 11 (с возможностью поворота вокруг них) установлены подпружиненные изогнутые ножи 12. Привод ножей 12 выполнен в виде клиновой-скобы 13 со стержн ми 14 на концах. Стержни 14 св заны между собой планкой 15. Клинова скоба 13 размещена между верхней 2 и нижней 3 плитами. В клиновой скобе 13 имеютс осевые каналы дл размещени в них стоек 1 и кабел 4. В нижней плите 3 выполнены осевые каналы под стержни 14. Клинова скоб 13 установлена с возможностью взаимодействи с наружной поверхностью ножей 12. На кабеле 4 закреплен зажимThe device consists of a body in the form of rigidly interconnected pillars 1, top 2 and bottom 3 plates with axial channels for cable 4. In the top plate 2 there is a cable sealing unit 5 4. The top plate 2 is rigidly connected to the casing 6, which is connected with an intermediate coil 7, installed at the mouth of 8 wells under the faceplate 9 with a tubing 10 attached to it by a column 10. On the posts 1, hinged on the axles x 11 (rotatably around them), spring-loaded curved knives 12 are installed. The drive of the knives 12 is made in the form of a wedge-bracket 13 with rods 14 at the ends. The rods 14 are interconnected by a bar 15. A wedge bracket 13 is placed between the upper 2 and lower 3 plates. In the wedge bracket 13 there are axial channels for accommodating the struts 1 and the cable 4. In the bottom plate 3 axial channels are made under the rods 14. The wedge brackets 13 are installed with a possibility of interaction with the outer surface of the knives 12. A clamp is fixed on the cable 4

16, размещенный между нижней плитой 3 и планкой 15с возможностью упора в последнюю,, С целью обеспечени взрывобезопасности кожух 6 заполн етс диэлектрическим маслом.16 placed between the bottom plate 3 and the bar 15c with the possibility of abutting the last, in order to ensure explosion safety, the casing 6 is filled with dielectric oil.
Устройство работает следующим образом .The device works as follows.
Если в процессе эксплуатации скважины произошло самопроизвольное отвинчивание насоса, колонны 10 труб или их слом, сопровождаемое падением на забой, то кабель 4, прикрепленный к насосу и колонне 10 труб, начинает увлекатьс в скважину. При этом зажим 16, закрепленный на кабеле 4, также смещаетс вниз и, упира сь в планку 15, начинает перемещать клиновую скобу 13. Последн , взаимодейству с наружной поверхностью ножей 12, заставл ет их поворачиватьс вокруг осей 11. Происходит перерезание кабел 4 ножами 12.If, during the operation of a well, spontaneous unscrewing of the pump, string 10 of pipes or their breakdown followed by falling to the bottom occurred, then cable 4 attached to the pump and string 10 of pipes begins to get carried away into the well. In this case, the clamp 16 fixed on the cable 4 also moves downward and, abutting against the bar 15, begins to move the wedge bracket 13. Lastly, interacting with the outer surface of the knives 12, causes them to rotate around the axes 11. The cable 4 is cut by knives 12 .
Таким образом, предлагаемое устройство дл аварийного перерезани кабел погружного электроцентробежно - го насоса предотвращает повреждение наземного оборудовани и травмирование обслуживающего персонала увлекающимс в скважину в случае аварии кабелем .Thus, the proposed device for emergency cutting of the cable of a submersible electric centrifugal pump prevents damage to the ground equipment and injury to the maintenance personnel carried by the cable to the well in the event of an accident.
