Dynamic Model and Stick-slip Reduction Characteristics of a New Torsional Vibration Tool

工程科学与技术, 2020
In the process of oil and gas exploitation, with the increase of drilling depth, the rock hardness is increased, and the downhole friction resistance is larger, the drill string system is prone to stick-slip vibration, which may lead to premature ...
