      <abstract xml:lang="ru">
        <p>Искривление скважин, т.е. отклонение оси скважины от ее проект­ного профиля, явление в высшей степени нежелательное, часто приводя­щее к невыполнению буримой скважиной поставленных перед ней геоло­гических задач и приносящее большие убытки народному хозяйству. По­этому выявление и изучение всех факторов, влияющих на искривление колонковых скважин, является актуальным и важным вопросом.</p>

      <abstract xml:lang="en">
        <p>Well curvature, i.e. deviation of the well axis from its design profile, is a highly undesirable phenomenon that often leads to failure of the drilled well to fulfill its geological tasks and brings great losses to the national economy. Therefore, the identification and study of all factors affecting the curvature of core wells is an urgent and important issue.</p>
