      <abstract xml:lang="ru">
        <p>Наиболее производительным способом бурения с продувкой воздухом яв­ляется бурение с использованием погружных пневмоударников. Применение этого прогрессивного метода бурения ограничивается осложнениями, обуслов­ленными притоками пластовых вод в скважину, которые вызывают образование шламовых сальников и пробок ...</p>

        <p>The most productive method of drilling with air blowing is drilling with the use of submersible pneumatic drills. Application of this progressive drilling method is limited by complications caused by formation water inflows into the well, which cause formation of slurry glands and plugs ...</p>
