Abstract

FIELD: mining industry. SUBSTANCE: invention relates to technical means for down-the-hole drilling, namely to gear for running of distorted section of hole and drilling of new shaft. Gear for distortion of holes includes rock breaking tool with checker, face motor with housing and shaft, upper and lower units of deflecting elements mounted correspondingly above and below face motor. Deflecting elements are made extendable in radial direction in diametrical opposition to each other. Unit of upper deflecting element has housing rigidly coupled to housing of face motor, extending pistons with return springs and sealing rings rigidly coupled to upper deflecting element with the help of rods. Inner space of tubular housing has limiting bushing with radial holes. Unit of lower deflecting element incorporates housing and shaft rigidly coupled correspondingly to housing and shaft of face motor, ring piston composed of upper and lower parts located between housing and shaft, space above upper part of piston hydraulically communicates with flow duct of shaft through hole. Side surface of piston has circular grooves interacting with spherical heads of spring-loaded pushers rigidly coupled to deflecting element. Gear for distortion of holes is transferred from transportation into working position by switching on of drilling pump after orientation of gear in specified heading. With supply of flushing fluid upper deflecting element extends thanks to direct action of summary pressure difference in face motor and checker of drill bit on piston. Extension and registration of lower deflecting element takes place as result of interaction of circular grooves in side surface of lower part of ring piston moving downwards under pressure of flushing fluid equal to pressure difference in checker with heads of pushers. When drilling pump is switched off after drilling of necessary interval gear is again transferred into transportation position by return springs of upper and lower unit of deflecting elements. EFFECT: increased strength of parts and reliability of operation of unit controlling lower extending element of gear.

Изобретение относится к техническим средствам для наклонного бурения, а именно к устройствам для проводки искривленного участка скважин и забуривания нового ствола. Устройство для искривления скважины содержит породоразрушающий инструмент с насадкой, забойный двигатель с корпусом и валом, верхний и нижний узлы отклоняющих элементов, установленные соответственно выше и ниже забойного двигателя. Отклоняющие элементы выполнены выдвижными в радиальном направлении диаметрально противоположно друг другу. Узел верхнего отклоняющего элемента содержит корпус, жестко связанный с корпусом забойного двигателя, выдвижные поршни с возвратными пружинами и уплотнительными кольцами, жестко связанные с верхним отклоняющим элементом с помощью штоков. Во внутренней полости трубчатого корпуса установлена ограничительная втулка с радиальными отверстиями. Узел нижнего отклоняющего элемента состоит из корпуса и вала, жестко связанных соответственно с корпусом и валом забойного двигателя, кольцевого поршня, состоящего из верхней и нижней частей, размещенного между корпусом и валом, полость над верхней частью поршня гидравлически сообщена с проходным каналом вала через отверстие. На боковой поверхности поршня выполнены круговые канавки, взаимодействующие со сферическими головками подпружиненных толкателей, жестко связанных с отклоняющим элементом. Устройство для искривления скважины переводится из транспортного положения в рабочее путем включения бурового насоса после ориентирования устройства в заданном азимуте. При подаче промывочной жидкости верхний отклоняющий элемент выдвигается за счет непосредственного воздействия суммарного перепада давлений в забойном двигателе и насадке долота на поршне. Выдвижение и фиксация нижнего отклоняющего элемента происходит в результате взаимодействия круговых канавок на боковой поверхности нижней части кольцевого поршня, перемещающегося вниз под давлением промывочной жидкости, равного перепаду давления в насадке с головками толкателей. При выключении бурового насоса после бурения необходимого интервала устройство вновь переводится в транспортное положение возвратными пружинами верхнего и нижнего узлов отклоняющих элементов. Технический результат от применения предлагаемой конструкции заключается в повышении прочности деталей и надежности работы узла управления нижним выдвижным элементом устройства.The invention relates to technical means for directional drilling, and in particular to devices for posting a curved section of wells and drilling a new trunk. A device for bending a well comprises a rock cutting tool with a nozzle, a downhole motor with a housing and a shaft, upper and lower nodes of the deflecting elements mounted respectively above and below the downhole motor. The deflecting elements are made sliding in the radial direction diametrically opposite to each other. The node of the upper deflecting element comprises a housing rigidly connected to the casing of the downhole motor, retractable pistons with return springs and o-rings, rigidly connected to the upper deflecting element using rods. A restriction sleeve with radial holes is installed in the inner cavity of the tubular body. The node of the lower deflecting element consists of a housing and a shaft rigidly connected respectively to the housing and the shaft of the downhole motor, an annular piston consisting of upper and lower parts located between the housing and the shaft, the cavity above the upper part of the piston is hydraulically in communication with the shaft passage through the hole. On the side surface of the piston, circular grooves are made, interacting with the spherical heads of the spring-loaded pushers, rigidly connected with the deflecting element. The device for bending the well is transferred from the transport position to the working one by turning on the mud pump after orienting the device in a given azimuth. When flushing fluid is supplied, the upper deflecting element extends due to the direct effect of the total pressure drop in the downhole motor and the nozzle of the bit on the piston. The extension and fixation of the lower deflecting element occurs as a result of the interaction of circular grooves on the side surface of the lower part of the annular piston moving downward under the pressure of the flushing fluid, equal to the pressure drop in the nozzle with the heads of the pushers. When you turn off the mud pump after drilling the required interval, the device is again transferred to the transport position by the return springs of the upper and lower nodes of the deflecting elements. The technical result from the application of the proposed design is to increase the strength of the parts and the reliability of the control unit lower drawer element of the device.
