(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ИСКРИВЛЕНИЯ СКВАЖИН(54) DEVICE FOR MEASURING THE CURVE OF WELLS

1one

Изобретение относитс  к технике измерени  и контрол  за направлением, бур щейс  скважины при геофизических исследовани х.The invention relates to a technique for measuring and controlling the direction of a drilling well during geophysical surveys.

Известны устройства дл  измерени  искривлени  скважин, содержащие два взаимно перлендикул рных магнитомодул ционных датчика, бесконтактный преобразователь угла наклона и азимута с ма тником и источник тока. Такие устройства не имеют достаточной точности измерени  величин измерительных углов.Borehole measurement devices are known, comprising two mutually perindicular magnetically modulated sensors, a non-contact tilt and azimuth transducer with a key and a current source. Such devices do not have sufficient accuracy in measuring the measurement angles.

Предлагаемое устройство дл  повышени  точности измерени  и расширени  диапазона измерени  величин измерительных углов снабжено дополнительным магнитомодул ционным датчиком , расположенным взаимно перпевдикул рно первым двум и размешенным на одной оси с преобразователем угла наклона и азимута, выполненного в виде трех взаимно перпендикул рных катушек, внутри которых расположена измерительна  рамка, жестко св занна  с ма тником , нричем две катушки, пересекающиес  с осью устройства, подключены к источнику квадратурных токов, а треть  служит дл  съема сигнала.The proposed device for improving the accuracy of measurement and expansion of the measurement range of measurement angles is provided with an additional magnetic modulation sensor, located mutually perpendicular to the first two and placed on the same axis with an angle and azimuth transducer, made in the form of three mutually perpendicular coils, inside which is located the measuring a frame rigidly connected to the master, like two coils intersecting with the axis of the device, are connected to the source of quadrature currents, and the three It serves to pick up the signal.

I На чертеже схематично показано предлагаемое устройство.I The drawing schematically shows the proposed device.

Устройство содержит немагнитный корпус , жестко св занные с ним мапштомодул дион ные датчики 2. 3, 4, образующие пространственную пр моугольную систему координат, преобразователь угла наклона и азимута, состо  щий из катущек 5 и 6, пересекающихс  на оси 7 во взаимно перпендикул рных плоско, ст х и прикрепленных жестко к корпусу, причем катущки 5 и 6 запитаны квадратурными токами дл  создани  вращающегос  магнитно, го пол , измерительную рамку 8, закрепленную на внещнем кольце 9 внутреннего карданного подвеса 10, ма тник 11, жестко св за ный с измерительной рамкой, катушку 12 сий ти  сигнала.The device contains a non-magnetic body, rigidly connected with it, a maptomodule sensors 2. 3, 4, forming a spatial rectangular coordinate system, a tilt and azimuth transducer, consisting of coils 5 and 6, intersecting on axis 7 in mutually perpendicular flat directions. , st x and attached rigidly to the housing, the coils 5 and 6 being powered by quadrature currents to create a rotating magnetic field, the measuring frame 8 fixed on the outer ring 9 of the internal gimbal 10, fixed 11 this decline frame coil 12 minute vacancies signal.

При отклонении колонны бурильных труб ol положени  вертикали ма тник устанавливаетсй в направлении вертикали и измен ет положа ние св занной с ним рамки относительно нло скости вращающегос  магнитного пол  и И ней наводитс  з. д. с. Амплитуда наведенной э. д. с. определ ет значение угла наклона, а фаза - угол азимута.When the drill pipe string deviates ol, the vertical position of the antenna is set in the vertical direction and changes the position of the associated frame relative to the flatness of the rotating magnetic field, and H is induced by it. d. The amplitude of the induced e. d. determines the value of the angle of inclination, and the phase, the azimuth angle.
