      <abstract xml:lang="ru">
        <p>В процессе бурения за счет механической работы породоразрушающего инструмента в призабойной зоне выделяется тепло. В результате происходит нарушение естественного температурного и агрегатного состояния керна мерзлых пород. Изучение механизма протаивания керна мерзлых пород при бурении, выяснение закономерностей процесса протаивания для сознательного регулирования и нормализации его температурного режима имеет практическое значение.</p>

        <p>In the process of drilling, heat is generated in the bottom-hole zone due to mechanical work of the rock-destroying tool. As a result, the natural temperature and phase state of frozen rock cores is disturbed. Studying the mechanism of frozen rock core thawing during drilling, elucidating the regularities of the thawing process for deliberate regulation and normalization of its temperature regime are of practical importance.</p>
