      <abstract xml:lang="ru">
        <p>Рассматривается проблема увеличения дебита скважин путем расширения зоны уста­новки фильтра. Приводятся некоторые действующие конструкции расширителей с анали­зом их достоинств и недостатков. Дается принципиальная схема нового расширителя, раз­работанного на кафедре разведочного бурения МГГРУ.</p>

        <p>The problem of increasing the flow rate of wells by expanding the filter installation area is considered. Some existing constructions of reamers with the analysis of their advantages and disadvantages are given. A schematic diagram of a new reamer, developed at the Department of Exploration Drilling of MGRU, is given.</p>
