Head Kozhevnykov Anatoliy, Registration Date 03-04-2003 Organization National Mining University popup.description2 It was be established that possibility of length compressed part of drilling column regulation exist. It permit in case of necessity reduce this length and reduce wastes of expenses of energy on friction column about walls of well, wear of external surface of drilling column. It was be established that the change of relation between inside and outside diameters of the drilling column reduce wastes of energy, which passed in view of axial load on boring tool. It allow intensificate process of destruction of rocks, reduce deviation of well from vertical. The increasing drilling column mass of one meter give increasing of wastes of expenses of energy on the inertial component and reduce wastes on friction column about walls of well and reduce rotary moment on upper end of the drilling column. It give possibility of increasing speed of rotary.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
