Power consumption during core drilling

Article preview

Drilling of wells is accompanied by expenditure of a certain amount of energy, which is spent to overcome friction in the ground “equipment, to rotate the drill string, the destruction of rock at the bottom hole and the friction of the drill tip on the rock.The article analyzes the power formulas and gives the results of experimental studies of two components of power: 1) on the destruction of rock and friction of the drill tip; 2) on the rotation of the drill string.

Selection of engine power for downhole operations when drilling deep exploratory wells

Article preview

When selecting the engine power for the machine drive, the determining factors are the power consumption for drilling process and production of downhole operations. The latter are of great importance when working at great depths, where the rock strength increases significantly and the time of the drill bit stay at the bottomhole decreases. Below we propose a method of determining the required engine power for downhole operations.

О ПОТЕРЯХ МОЩНОСТИ В ПОВЕРХНОСТНОМ ОБОРУДОВАНИИ АГРЕГАТОВ КОЛОНКОВОГО БУРЕНИЯ

Article preview

Колонковое бурение нашло широкое применение в геологоразве­дочном деле и горной промышленности. Парк станков колонкового буре­ния пополняется новыми марками. Имеются агрегаты для бурения в са­мых различных геологических условиях и самых различных глубин сква­жин (от 50—100 до 1000—1500 м и выше). Однако, несмотря на большой объем буровых работ и их длитель­ное применение, вопросам привода буровых установок уделялось очень мало внимания. В предлагаемой статье рассматривается часть общего вопроса о мощности, необходимой для ведения процесса бурения скважин.
