(54) БУРОВАЯ УСТАНОВКА(54) DRILLING INSTALLATION

Изобретение относитс к оборудованию дл бурени скважин и может быть использовано в буровых машинах с применением подвижного вращател .The invention relates to equipment for drilling wells and can be used in drilling machines using a rolling rotator.

Известны буровые установки, имеющие мачту, подъемник в виде бесконечной цепи, подвижный вращатель с патроном, соединенный с цепью, трубодержатель. Подъемник обеспечивает перемещение подвижного вращател на длину свечи или меньще ее (при работе с перехватом), свинчивание и развинчивание резьбовых соединений производитс вращателем, а подача свечи на ось скважины и установка ее в магазин выполн етс либо вручную 1, либо манипул тором 2.Known drilling rigs with a mast, a lift in the form of an endless chain, a movable rotator with a cartridge connected to the chain, a pipe holder. The elevator provides movement of the movable rotator to the candle length or less (when working with interception), screwing and unscrewing the threaded connections is performed by the rotator, and the candle is fed to the well axis and installed in the magazine either manually 1 or by manipulator 2.

Эти установки имеют существенный недостаток , т. е. основные операции при спуске-подъеме бурового снар да выполн ютс последовательно. Совмещена лишь установка свечи в магазин и подача ее к скважине с операци ми по перемещению бурильной колонны и свинчиванием-развинчиванием . Поэтому затраты времени на выполнение спуска-подъема этими установками будут относительно велики.These installations have a significant disadvantage, i.e., the main operations during the descent and ascent of the drill string are performed sequentially. Only the installation of the spark plug into the magazine and its supply to the well with the operations of moving the drill string and screwing-unscrewing are combined. Therefore, the time spent on the implementation of the descent-lift these settings will be relatively large.

Целью изобретени вл етс ускорение проведени вспомогательных операций по перемещению бурильной колонны и ненагруженного вращател .The aim of the invention is to accelerate the auxiliary operations for moving the drill string and the unloaded rotator.

Поставленна цель достигаетс тем, что вращатель снабжен зажимом со средством дл попеременного присоединени его к обеим ветв м цепи, а трубодержатель снабжен со средством дл присоединени его к одной из ветвей цепи.The goal is achieved by the fact that the rotator is provided with a clip with means for alternately connecting it to both branches of the chain, and the tube holder is provided with means for connecting it to one of the branches of the chain.

Па чертеже показана схема предлагаемой установки.Pa drawing shows the scheme of the proposed installation.

Предлагаема бурова установка содержит мачту 1, трубодержатель 2, располо10 женный на направл ющих мачты, подвижный вращатель 3 с патроном 4, перемещаемый соосно скважине подъемником 5 в виде бесконечной цепи, и манипул тор 6. Подвижный вращатель 3 размещен на каретке 7, снабженной зажимом 8 дл поочередного присоединени к ветв м 9 н 10 цепи . Каретка размещена на направл ющих мачты. Относительно нее подвижный вращатель 3 может перемещатьс вдоль оси The proposed drilling installation comprises a mast 1, a tube holder 2 located on the guide masts, a movable rotator 3 with a cartridge 4, moved coaxially with the well by the lift 5 in the form of an endless chain, and a manipulator 6. The movable rotator 3 is placed on the carriage 7 equipped with a clamp 8 for alternately joining the branches of the 9 n 10 chain. The carriage is placed on the guide masts. Relative to it, the movable rotator 3 can move along the axis

20 скважины гидроцилиндром II. Трубодержатель 2 имеет зажим 12 дл присоединени к ветви 9 цепи подъемника. Подъемник 5 установлен на основании 13.20 wells hydraulic cylinder II. The tube holder 2 has a clamp 12 for connection to the branch 9 of the hoist chain. Lift 5 is installed on the base 13.

Claims

Work on the drilling rig when drilling 30 is carried out as follows. When drilling, the tube holder 2, which holds the drilling projectile, is located in the lower part of mast 1 on the base 13. The clamp 12 of the tube holder 2 is open, i.e. the tube holder 2 is disconnected from the branch lifter 9 9. lift 5. Gripping bodies 14 and 15 of the tube holder 2 and the cartridge 4 all the time located on the axis 16 of the well. The drilling and extension operations are carried out in the same way as in known installations with a movable rotator. Installation work when performing tripping operations. The cycle “Descent. The initial position of the mechanisms. The movable rotator is connected with a clip 8 to the branch 10 of the lift 5 and is located in the middle part of the mast /, the gripping members 15 of the cartridge 4 are open. The tube holder 2 is connected to the branch 9 of the lifter 5 by the clamp 12, holds the drill string and is located in the middle part of the mast 1 under the movable rotator 3. When the start button at the control zero is pressed, the operations are carried out automatically in the following sequence. The manipulator 6 delivers another candle to the axis 16 of the borehole, the movable rotator 5 by the hydraulic cylinder 11 rises to the upper position, captures the lower end of the candle held by the manipulator 6, and feeds it to the drill thread, the cartridge 4 of the movable rotator 3 rotates a candle, connects a threaded connection, at the end of the operation in the chuck 4 the gripping bodies 15 open, the lift 5 lowers the tube holder 2 with the clamped drill string down, at the same time the rotator 3 connected to the opposite end Noah 10 lifts 5, rises up, at the end of the stroke, the gripping bodies 15 of the chuck 4 of the rotator 3 are closed on the pipe, and the gripping bodies 14 of the tube holder 2 are opened, the lift 5 is reversed, and the movable rotator 5 with the clamped drill snaps down tube holder 2 rises. When the rotator 3 and the tube holder 2 descend from the middle of the mast 1, the lift 5 stops, the tube holder 2 engages the drill 14 with organs 14, and the gripping members 15 of the cartridge 4 of the rotator 3 open. The mechanisms are again in their original position (for repetition, no cycle). Cycle “Rise. The mechanisms are brought to their original position, similar to the position of the mechanisms in the cycle - "Descent. When you click the Start button on the remote control, the operations are performed automatically in the following sequence. The gripping bodies 15 of the chuck 4 of the rotor 3 are closed on the pipe of the column, the gripping bodies 14 of the pipe holder 2 are opened, the lift 5 on the branch 10 lifts the movable rotator 3 with the drill bit to the upper position, simultaneously unloaded pipe holder 2 connected to the opposite branch 9 of the lift 5, lowers way down. At the end of the stroke, the gripping bodies 14 of the tube holder 2 are closed on the pipe, and the gripping bodies 15 of the natron 4 of the rotator 3 are opened, the lift 5 is reversed, while the tube holder 2 with the drilling projectile rises, the rotator 3 simultaneously lowers. When the rotator 3 and the tube holder 2 meet in the middle of the mast /, the lift 5 stops, the rotator raises the hydraulic cylinder 11, the gripping bodies 15 of the cartridge 4 captures the column above the threaded connection and, raps; , left on the axis 16 wells. The candle is turned away by the manipulator 6, the gripping bodies 15 of the cartridge 4 of the rotator 5 are opened, the rotator is turned by the hydraulic cylinder: 11 is lowered, and the manipulator 6 pulls the candle from the axis 16 of the well. Then the cycle repeats. The proposed installation allows, without significant complication of the kinematics, to significantly accelerate the performance of tripping operations by combining time-consuming operations to move the drill string and the unloaded rotator. Claims of the Invention Drill rig comprising a mast, an endless chain hoist, a movable rotator with a cartridge connected to a chain, a tube holder, characterized in that, in order to speed up the auxiliary operations of moving the drill string and the unloaded rotator, the rotator is provided with a clip alternately connecting it to both branches of the chain, and the tube holder is provided with a clip with means for connecting it to one of the branches of the chain.
