众所周知,金刚石虽然硬度很高,但也很脆.因此,采用金刚石钻头钻进时,如何防止由于高速回转的钻具振动所引起的动负荷就具有重要意义.金刚石钻进中的振动,是由各种原因引起的,一般分为扭转振动、纵向振动和横向振动.根据振动的原因可采取一些有效的预防措施,如正确地安装钻探设备,使用回转平衡性好(不弯曲、壁厚均匀、连接同心度好)的钻具,以及选择合理
As we all know, although the diamond is very high hardness, but also very brittle, therefore, the use of diamond bit drilling, how to prevent due to high-speed drilling vibration caused by the dynamic load is of great significance .Drilling diamond in vibration by A variety of causes, generally divided into reverse vibration, longitudinal vibration and lateral vibration.According to the vibration reasons can take some effective preventive measures, such as the correct installation of drilling equipment, the use of rotary balance (no bending, uniform wall thickness, Concentricity is good) drill, and the choice is reasonable
