Abstract

Инструмент и система для направленного роторного бурения, описанные в данной заявке, объединяют методы с отклонением долота и методы с направлением долота для активного изменения направления траектории ствола скважины. В этой системе отклонение бурового долота ограничивается одной степенью свободы относительно системы координат, которая фиксируется на и вращается с инструментом для направленного роторного бурения, что приводит к упрощенному прикреплению узла долота и механизма блока смещения. Кроме того, управление направлением бурения скважины осуществляется путем динамического управления пространственной фазой и амплитудой когерентных симметричных двунаправленных возвратно-поступательных отклонений бурового долота по отношению к фиксированной наземной системе координат при вращении инструмента, а также одновременного отклонения и направления долота. Амплитуду и силу отклонений долота можно регулировать во время операций управления направлением бурения для того, чтобы при необходимости динамически регулировать мгновенный темп естественного искривления ствола скважины. В случае, когда управление направлением бурения не используется, долото может быть механически заблокировано в нейтральном положении.The tool and system for directional rotary drilling described in this application combine methods with bit deviation and methods with the direction of the bit to actively change the direction of the wellbore path. In this system, the deviation of the drill bit is limited to one degree of freedom relative to the coordinate system, which is fixed on and rotates with the tool for directional rotary drilling, which leads to a simplified attachment of the bit assembly and the displacement unit mechanism. In addition, the direction of well drilling is controlled by dynamically controlling the spatial phase and amplitude of coherent symmetric bi-directional reciprocating deviations of the drill bit relative to a fixed surface coordinate system during tool rotation, as well as simultaneous deflection and direction of the bit. The amplitude and force of deviations of the bit can be adjusted during the drilling direction control operations in order to dynamically adjust the instantaneous rate of natural curvature of the wellbore if necessary. In the case where the direction control is not used, the bit can be mechanically locked in the neutral position.
