      <abstract xml:lang="ru">
        <p>При бурении вертикальных и пологонаклонных скважин объемный инстру­мент занимает рабочее положение под действием его собственной тяжести. Определение зависимости коэффициента сопротивления СR, силы сопро­тивления жидкости FC и скорости движения съемного инструмента v от его веса, длины, угла наклона скважины, вязкости промывочной жидкости и вели­чины кольцевого зазора проводилось на специально изготовленном экспери­ментальном стенде методом падающего груза.</p>

        <p>When drilling vertical and declined wells, the volumetric tool takes the working position under the action of its own gravity. Determination of the dependence of the resistance coefficient CR, fluid resistance force FC and speed of movement of the removable tool v on its weight, length, angle of inclination of the well, viscosity of the flushing fluid and the size of the annular gap was carried out on a specially made experimental stand by the method of falling weight.</p>
