      <abstract xml:lang="ru">
        <p>В настоящее время пены применяются при бурении скважин на твердые полезные ископаемые в мерзлых породах, в условиях трудных по водоснабже­нию, при низких пластовых давлениях в проницаемых, трещиноватых и кавер­нозных, но относительно устойчивых породах.</p>

        <p>Currently, foams are used when drilling wells for solid minerals in frozen rocks, in conditions of difficult water supply, at low formation pressures in permeable, fractured and cavernous, but relatively stable rocks.</p>
