Description
Извегтны устройства дл производства спуско-подъемных операций при бурении скважин.Weaving devices for drilling operations are izvegtny.
Предлагаемое устройство отличаетс от известных применением двух одновременно работающих элеваторов и двух талевых оснасток. Канаты оснасток намотаны в разные стороны на часть двухсекционного барабана подъемной лебедки.The proposed device is different from the known use of two simultaneously operating elevators and two tackle accessories. Snap ropes are wound in different directions on the part of the two-section drum of the lifting winch.
Такое устройство сокращает врем , необходимое на подъем холостого элеватора, осуществл емый за счет веса опускаемой колонны, а не приводной мощности лебедки.Such a device reduces the time required to raise the idling elevator, due to the weight of the tower being lowered, and not the winch drive power.
На чертеже показана бурова установка с двум талевыми оснастками , перемещающимис спаренным кропблоком и двухсекционным барабаном лебедки.The drawing shows a drilling rig with two pulley attachments moving with a paired cropblock and a two-section winch drum.
Элеваторы 1 и 2 закреплены на двух самосто тельных канатах 3 и 4, которые перекинуть через ролики 5 спаренного перемещающегос кронблока 6. Канаты наматываютс на секции барабана 7, разделенного на две части ребордой. При вращении барабана один из канатов сматываетс , другой поднимаетс . Передвижной кронблок поочередно переносит каждый из элеваторов на ось скважины и обратно.Elevators 1 and 2 are fixed on two independent ropes 3 and 4, which are thrown over the rollers 5 of a paired moving crown block 6. The ropes are wound on a section of a drum 7, divided into two sections by a flange. As the drum rotates, one of the ropes coils, the other rises. A mobile crown block alternately transfers each of the elevators to the well axis and back.
Элеваторы, мен сь местами, поочередно поднимают колонну бурильных труб и отвод т свечи от оси скважины на каждый из двух подсвечников 8.The elevators, in places, alternately lift the drill string and divert candles from the well axis to each of the two candlesticks 8.
Вращение барабана лебедки реверсивное, кронблок выполн ют с дистанционным управлением.The winch drum rotation is reversible, the crown block is performed with a remote control.
Предлагаемое устройство упрощает механизацию отведени свечей от оси скважины на подсвечник, при этом врем спуско-подъемных операций не зависит от времени спуска или подъема холостого элеватора и складываетс , в основном, из времени подъема колонны и развинчивани свечи, спуска ее и свинчивани .The proposed device simplifies the mechanization of the discharge of candles from the borehole axis to the candlestick, while the time of the lifting and lifting operations does not depend on the time of descent or ascent of the idling elevator and is mainly composed of the time of lifting the column and unscrewing the candle, lowering it and screwing it.
