Description
Известны способы бурени скважин, когда пилот-скважину бур т роторным способом, а расширение ее ведут турбинным способом. Однако им присущи недостатки, заключающиес в том, что эти операции выполн ютс последовательно и поэтому на сооружение скважины затрачиваетс много времени.Well boring methods are known when the pilot well is drilled in a rotary way, and its expansion is carried out in a turbine way. However, they have the drawbacks that these operations are performed sequentially and therefore a lot of time is spent on the construction of the well.
Предлагаемый способ не имеет этого недоста7 ка, так как пи.тот-скважину бур т долотом, соединенным с Р1еподвижным валом трубобура. Одновременно ствол скважины расшир ют шарошками, установленными на вращающемс корпусе турбобура.The proposed method does not have this disadvantage, since the pi.tot-well is drilled with chisels connected to the P1 fixed shaft of the drill bit. At the same time, the borehole is expanded with the cones mounted on the rotating body of the turbo-drill.
На чертеже показана конструктивна схема устройства, посредством которого осун1,ествл етс способ.The drawing shows a structural diagram of the device by means of which the os1 is described.
К бурильным трубам через переводник / присоедин етс вал 2 турбобура , который приводитс во вращение от ротора через колонну Оури .тьны.х труб. На нижнем конпе вала установлено пилот-долото 5, а на вращающемс корпусе 4 турбобура-щарощки 5 и сальники 6 и 1, отдел ющие рабочую полость турбобура от затрубного пространства.A drill pipe 2 of the turbo-drill is driven to the drill pipe via a sub / rotation shaft, which is driven to rotate from the rotor through an Ouri column. A pilot bit 5 is installed on the lower crown shaft, and on the rotating case 4 there are turbodrill holes 5 and glands 6 and 1 separating the working cavity of the turbodrill from the annulus.
Жидкость, нагнетаема в трубы, поступает в верхнюю полую часть вала, откуда через отверстие попадает в рабочие органы турбобура, затем через нижнее отверстие выходит в нижнюю полую часть вала, из которого перетекает в пилот-долото (на чертеже показано стрелками)Устройство позвол ет вести бурение пилот-скважииы роторным ciioсобом и одновременно ее расширение-турбин1гым способом.The fluid injected into the pipes enters the upper hollow shaft, from where it enters the working bodies of the turbo-drill, then goes through the lower hollow into the lower hollow shaft, from which it flows into the pilot bit (shown in the drawing). drilling a pilot borehole with a rotary motor and simultaneously expanding it in a turbine way.
Предмет изобретени Subject invention
Способ бурени скважин при помощи турбобура и ротора, отличающийс тем, что, с целью ускорени процесса бурени , пилот-скважина буритс долотом, соединен} ым с валом турбобура, с одновременным расширение.м ствола скважин щарошками. установленными на вращак щемс корпусе трубобура.A method of drilling a well using a turbo-drill and a rotor, characterized in that, in order to speed up the drilling process, the pilot-hole is drilled with a chisel, connected to the shaft of the turbo-drill, with simultaneous expansion of the wellbore with sharoshkami. mounted on the rotor case of the tube tube.
