Изобретение относитс к бурению скважин, а именно к устройствам дл , проведени спуско-подъемных операций при бурении и ремонте скважин. jThe invention relates to the drilling of wells, namely, devices for carrying out tripping operations during drilling and repair of wells. j
Известен агрегат дл ремонта скважин , содержащий вышку, элеватор, силовую талевую систему подъема и опускани груза, горизонтальные мостки дл хранени и выдачи труб и манипу- |g л тор, закрепленный на вышке и служащий дл подачи труб с горизонтальных мостков на ось скважины или перемещени отсоединенной трубы с оси скважины на мостки i ..A well-known well repair unit comprising a tower, an elevator, a power tallest system for lifting and lowering cargo, horizontal walkways for storing and dispensing pipes, and a manipulator mounted on the tower and serving to feed pipes from horizontal runs to the well axis or to move disconnected pipe from the borehole axis to the gangway i ..
Основным недостатком этого устрой- ства вл етс сложность конструкции и управлени установкой трубы точно на устье скважины.The main disadvantage of this device is the complexity of the design and control of the installation of the pipe exactly at the wellhead.
Известно также устройство, содер- „ жащеа вышку, имеющую направл ющие, по которым двигаетс каретка, и силовую систему привода каретки . В каретке установлен вертлюг-вращатель и шарнирно св занный с ним элеватор. Эле- 5 ватор закреплен с возможностью поворота его на угол 90° относительно вышки с помощью гидроцилиндра. Автоматизированные мостки имеют приемный лоток и механизм перемещени трубы вдоль .It is also known a device comprising a tower, having guides along which the carriage moves, and a power system of the carriage drive. A swivel rotator and an elevator hinged to it are mounted in the carriage. The elevator is fixed so that it can be rotated at an angle of 90 ° relative to the tower using a hydraulic cylinder. Automated walkways have a receiving tray and a mechanism for moving the pipe along.
лотка. Во врем работы, например, после спуска очередной трубы, колонна труб закрепл етс спайдером, элеватор освобождаетс , поворачиваетс в сторону приемного лотка, при этом труба по лотку подаетс к элеватору, захватываетс им и поднимаетс вверх. Нижний конец трубы при этом скользит по лотку.tray. During operation, for example, after the descent of a regular tube, the string of pipes is fixed by the spider, the elevator is released, turned towards the receiving tray, while the pipe is fed to the elevator along the tray, trapped by it and raised up. The lower end of the tube slides along the tray.
Основным недостатком этого устройства вл етс то, что операции освобождени опущенной трубы (или уложенной на мостки) и прием трубы производ тс последовательно, разделены во времени, привод т к непроизводительным потер м времени, снижающим производительность спуско-подъемных операций .The main disadvantage of this device is that the operation of freeing the lowered pipe (or laid on the gangway) and receiving the pipe is performed sequentially, separated in time, leading to unproductive time losses, which reduce the performance of the launch and lift operations.
Цель изобретени - сокращение времени на спуско-подъемные операции.The purpose of the invention is to reduce the time for tripping.
Поставленна цель достигаетс тем, что механизм захвата выполнен в виде четырех жестко св занных между собой элеваторов, установленных с возможностью поворота относительно горизонтальной оси каретки, причем оси элеваторов расположены в одной вертикальной плоскости, а ось каждого элеватора образует с ос ми соседних элеThe goal is achieved by the fact that the gripping mechanism is made in the form of four rigidly interconnected elevators installed with the possibility of rotation relative to the horizontal axis of the carriage, the axes of the elevators being located in the same vertical plane, and the axis of each elevator forms
