        <p>По принципам разрушения горной породы механическое бурение скважин может осу­ществляться несколькими способами, отличающимися по своей физической природе. Для отбойки породы средней и высокой прочности применяют шарошечные долота с фрезерованным вооружением или армированные штырями из твердого сплава с высоким пре­делом прочности. Шарошечный способ бурения реализует принцип разрушения забоя за счет статического вдавливания вооружения, порода разрушается преимущественно выколом, час­тично блокированным сколом. С энергетической точки зрения такое воздействие на забой не является оптимальным ...</p>

        <p>According to the principles of rock destruction, mechanical drilling of wells can be carried out in several ways, differing in their physical nature. For medium- and high-strength rock, roller cone bits with milled cutting structure or reinforced with high-strength tungsten carbide pins are used. The roller cone method of drilling implements the principle of bottom-hole destruction due to static impingement of the cutting structure, the rock is destroyed mainly by a piercing, partially blocked chipping. From the energy point of view, such impact on the bottom hole is not optimal.</p>
