Description

Известные турбобуры обладают тем недостатком, что эффективность их применени  по мере увеличени  глубины скважины падает.The known turbo-drills have the disadvantage that the efficiency of their use decreases as the well depth increases.

Предлагаемое устройство не имеет этого недостатка, так как питание турбобура осуществл етс  от насоса, расположенного в призабойной зоне, причем приводом насоса  гзл етс  быстроходна  турбина или электродвигатель.The proposed device does not have this drawback, since the turbodrill is powered from a pump located in the near-wellbore zone, with the high-speed turbine or electric motor driving the pump.

На чертеже показана блок-схема предлагаемого устройства.The drawing shows a block diagram of the proposed device.

По бурильным трубам 1 нагнетаетс  промывочна  жидкость, котора  поступает в быстроходную турбину 2, вращающую насос (центробежный осевой) 3, а жидкость из него поступает в низконапорную турбину 4, вращающую долото 5. Часть жидкости из затрубного пространства через фильтр 6 поступает на реперкул цию в низконапорную турбину, что обеспечивает повышенное количество жидкости, направл емое в забой дл  очистки последнего от шлама.The drilling pipe 1 is pumped with flushing fluid that enters the high-speed turbine 2, the rotary pump (centrifugal axial) 3, and the fluid from it enters the low-pressure turbine 4, which rotates the bit 5. Part of the fluid from the annulus through the filter 6 is fed to a low-pressure turbine that provides an increased amount of fluid directed to the bottom to clean the latter from the sludge.

При применении предлагаемого устройства посланна  па забой и преобразованна  в нем гидравлическа  энерги  позвол ет получать турбобур с любым заданным соотношением между числом оборотов и вращающим моментом. В призабойпой зоне между забоем и областью расположени  приема насоса происходит интенсивна  местна  циркул ци , а образуемый шлам поднимаетс  в восход щем потоке жидкости .When using the proposed device, the sent downhole and the hydraulic energy converted in it allows to obtain a turbo-drill with any desired ratio between the number of revolutions and the torque. In the bottom-hole zone between the bottom and the pump intake area, local circulation is intense, and the sludge formed rises in an upward flow of fluid.

Предмет изобретени Subject invention

Устройство дл  бурени  глубоких скважин турбинным способом, отличающеес  тем, что, с целью улучшени  очистки призабойной зоны от выбуренной породы, питание турбобура осуществл етс  от насоса, расположенного в призабойной зоне, причем приводом насоса  вл етс  быстроходна  турбина или электродвигатель.A device for drilling deep wells by a turbine method, characterized in that, in order to improve the cleaning of the bottomhole zone from cuttings, the turbodrill is powered from a pump located in the bottomhole zone, the pump drive being a high-speed turbine or an electric motor.
