Description
В примен емых забойных двигател х шарошечное долото непосредственно соединено с валом этого двигател , и разрушение породы производитс по принципу дроблени .In the downhole motors used, the roller bit is directly connected to the shaft of this engine, and the destruction of the rock is carried out according to the principle of crushing.
Дл обеспечени разрушени породы скалыванием, что требует затраты меньшей мош.ности на бурение , в устройстве согласно изобретению забойный двигатель соедин етс с бурильными трубами при помощи эксцентричного переводника .In order to ensure the destruction of the rock by flaking, which requires less power to drill, the downhole motor is connected to the drill pipe with an eccentric sub in the device according to the invention.
На чертеже схе.матическн изображен продольный разрез устройства.The drawing schematically depicts a longitudinal section of the device.
На колонне бурильных труб I укреплен в нижней части эксцентричный переводник 2, к которому присоединен забойный двигатель 3 (турбобур или электробур), заключенный в кожух 4.On the string of drill pipes I, an eccentric sub 2 is attached to the bottom, to which a downhole motor 3 (turbo-drill or electric drill) enclosed in 4 is attached.
Кожух может быть выполнен не сплошным по длине, а в виде ;ескольких направл ющих. В нижней части кожуха имеютс отверсти 5The casing can be made not solid in length, but in the form of; a few guides. There are holes in the bottom of the casing 5
дл сообн ени полости кожуха с затрубным пространством.to communicate the cavity of the casing with the annular space.
На шпинделе забойного двигател 3 укреплено долото 6, производ шее разрушение породы.On the spindle of the downhole motor 3, a chisel 6 is strengthened, which causes destruction of the rock.
Долото совершает сложное движение . Оно вращаетс вокруг собственной оси и одновременно вращаетс вместе с корпусом вокруг оси кожуха. Таким образом, долото разрушает всю поверхность забо не дроблением, а боковым скалыванием , как при планетарном буренииChisel makes a complicated move. It rotates around its own axis and simultaneously rotates with the body around the axis of the casing. Thus, the chisel destroys the entire surface not by crushing, but by side cleaving, as in planetary drilling.
Предмет п з о б р е т е i и Subject matter of i and
Устройство дл бурени скважин забойным двигателе.м с одновременным вращением долота бурильными трубами, отличающеес тем, что, с целью смещени оси забой1ЮГО двигател относительно оси бурильных труб, забойный двигатель, номещенный в кожухе, соединен с бурильными трубами при помощи эксцентричного переводника.A device for drilling wells with a downhole motor. With simultaneous rotation of the bit by drill pipes, characterized in that, in order to displace the axis of the downhole motor relative to the axis of the drill pipe, the downhole engine nesmeshchenny in the casing is connected to the drill pipe with an eccentric sub.
