        <p>Эффективность бурения скважин с использованием газожидкостных смесей связана со способностью пен снижать трение и колебания колонны бурильных труб. Основными факторами здесь являются вязкость пены и диаметр ее пузырьков.</p>

        <p>the effectiveness of the foam flush drilling connects of foam ability to reduce the friction force and drilling shaft oscillation. The main factors are foam viscosity and foam bubble’s diameter.</p>
