      <abstract xml:lang="ru">
        <p>Разработка методики расчета глубины пневмоударного бурения о приме­нением газожидкостного очистного агента представляется весьма важной для правильной оценки возможностей пневмоударного бурения и определения ра­циональных режимов подачи газожидкостной смеси (ГЖС), обеспечивающих по­лучение максимальных энергетических параметров пневмоударника при мини­мальных потерях давления в скважине.</p>

        <p>The development of a methodology for calculating the depth of pneumatic percussion drilling with the use of gas-liquid cleaning agent seems to be very important for the correct assessment of the possibilities of pneumatic percussion drilling and determination of rational modes of supplying gas-liquid mixture (GMS), providing the maximum energy parameters of the pneumatic percussion at minimum pressure losses in the well.</p>
