Abstract

FIELD: drilling of oil and gas wells; controlled change of well inclination angle. SUBSTANCE: straight sections of well are drilled with rotating drilling bit and stopped pipe string, and well inclined sections are drilled with simultaneous rotation of the downhole motor rotor and pipe string in same direction and speed. The device for embodiment of the offered method has downhole motor whose body is connected with pipe string and rotor rotates relative to longitudinal axis of the body, deflected bit shaft carrying drilling bit, connecting unit of rotor and bit shaft, bearing support and gager. Connecting unit is made in form of articulated coupling. Support of bit shaft is spherical with center lying on the motor axis and bit shaft is installed in support for rotation relative to the center. When rotor and bit shaft rotate, drill rotates and drills the well straight section. In concurrent synchronous rotation of rotor and pipe string, angle of inclination of bit shaft is stabilized and inclined section is drilled, and final diameter is formed with the help of gager. EFFECT: higher operate reliability and extended operation capabilities. 3 cl, 1 dwg

Использование: управление изменением угла отклонения при бурении нефтяных и газовых скважин. Сущность изобретения: прямые участки скважины бурят при вращении бурового долота и застопоренной колонне бурильных труб, а наклонные участки бурят при одновременном вращении ротора двигателя и колонны бурильных труб в одну сторону с равной частотой. Устройство содержит забойный двигатель, корпус которого соединен с колонной бурильных труб, а ротор вращается относительно продольной оси корпуса, отклоняемый шпиндельный вал, несущий буровое долото, соединительный узел ротора и шпиндельного вала, подшипниковую опору и калибратор, причем соединительный узел выполнен в виде шарнирной муфты, опора шпиндельного вала выполнена сферической с центром, лежащим на оси двигателя, а шпиндельный вал установлен в опоре с возможностью вращения относительно ее центра. При вращении ротора и шпиндельного вала долото вращается и разбуривает прямой участок скважины. При одновременном синхронном вращении ротора и колонны бурильных труб стабилизируется угол наклона шпиндельного вала и разбуривается наклонный участок, а окончательный диаметр формируется с помощью калибратора).Usage: control the change in the angle of deviation when drilling oil and gas wells. The inventive straight sections of the well are drilled during rotation of the drill bit and a stalled drill pipe string, and inclined sections are drilled while the rotor of the engine and the drill string are rotated in the same direction at the same frequency. The device comprises a downhole motor, the casing of which is connected to the drill pipe string, and the rotor rotates relative to the longitudinal axis of the casing, a deflectable spindle shaft carrying a drill bit, a rotor and spindle shaft connection unit, a bearing support and a calibrator, the connection unit being made in the form of an articulated coupling, the support of the spindle shaft is made spherical with the center lying on the axis of the motor, and the spindle shaft is mounted in the support with the possibility of rotation relative to its center. When the rotor and spindle shaft rotate, the bit rotates and drills a straight section of the well. With simultaneous synchronous rotation of the rotor and the drill pipe string, the angle of inclination of the spindle shaft is stabilized and the inclined section is drilled, and the final diameter is formed using a calibrator).
