      <abstract xml:lang="ru">
        <p>При разведке месторождений полезных ископаемых все шире при­меняется бурение сплошным забоем, т.е. без отбора керна. Бескерновое бурение дает возможность увеличить производительность за счет увели­чения механической скорости бурения, сокращения времени на спуско­подъемные операции, ликвидации затрат времени на заклинку керна, упрощения технологии бурения и соответственно позволяет удешевить стоимость погонного метра бурения.</p>

      <abstract xml:lang="en">
        <p>When exploring mineral deposits, drilling with a solid bottom hole, i.e. without coring, is being used more and more widely. Coreless drilling makes it possible to increase productivity by increasing the mechanical speed of drilling, reducing the time for downhole operations, eliminating the time spent on coring, simplifying drilling technology and, accordingly, reduces the cost per linear meter of drilling.</p>
