Information × Registration Number 0212U001511, 0106U004135 , R & D reports Title Optimization of the parameters of diamond drilling with pulsed flushing and the development of rational layout of drill strings popup.stage_title Head Kozhevnykov Anatoliy, Registration Date 07-02-2012 Organization National Mining University popup.description2 As a result, studies have provided theoretical curves to calculate the contact temperature in diamond mode with pulse cleaning expenses flush fluid flow pressure of drilling fluid and clean face and well. Also established a functional connection between the geometric and weight characteristics of drill pipes, on the one hand, and the wall thickness will-sterile tubes, on the other side. In theory, a relation of length compressed and stretched parts of the drill pipe with wall thickness of drill pipe. The dependence of the cost of power to rotate the drill string and the stresses in the material from the drill pipe wall thickness of the drill pipe. Conducted bench tests dependency of hydraulic characteristics of the drill pipe wall thickness, and feed the washing liquid. Product Description popup.authors Кузін Ю.Л.
