      <abstract xml:lang="ru">
        <p>Одним из наиболее распространенных видов геологических осложнений, возникающих при бурении скважин по многолетнемерзлым горным породам, является нарушение целостно­сти ствола вследствие изменения естественного напряженного состояния окружающего масси­ва. Закрепление стенок скважины с помощью обсадных труб требует перехода на меньший диаметр бурения, а использование тампонажных материалов для цементации трещиноватых пород мало эффективно, поскольку трещины, как правило, заполнены льдом, препятствующим проникновению в них тампонажного материала ...</p>

      <abstract xml:lang="en">
        <p>One of the most common types of geological complications arising when drilling wells through permafrost rocks is the violation of wellbore integrity due to changes in the natural stress state of the surrounding massif. Securing the wellbore walls with casing requires switching to a smaller drilling diameter, and the use of grouting materials for grouting fractured rocks is ineffective, since cracks are usually filled with ice, preventing the penetration of grouting material into them.</p>
