Suppression of Instabilities in Drilling Operations through Targeted Energy Transfer,. In particular, in deep-drilling operations it can be difficult to maintain a smooth cutting process at bit-rock interfaces. Among other disturbances and uncertainties in such operations, we mention the non-homogeneity of rock, the unavoidable friction effects (which are further complicated by flui审问 发表于 2025-3-29 12:22:12
