牙轮钻机的钻具在钻进过程中必定要产生振动,由此产生的动负荷对钻具自身和钻机其它零件的寿命有着很大的影响,此外,也导致电器元件失控和液压系统管接头松动漏油等现象。因此,摸清钻具的振动参数,从而设法减轻钻具的振动,对保护钻头轴承、柱齿;减轻钻杆的疲劳破坏,防止加压链条跳链,提高钻进速度,对改进钻机设计有关参数;将有所裨益的。
Drill rig cone vibration in the drilling process must be generated, the resulting dynamic load on the drilling rig itself and other parts of the rig life has a great impact, in addition, it also led to the loss of electrical components and hydraulic system pipe fittings Loose oil spills and other phenomena. Therefore, to find out the vibration parameters of the drilling tool, so as to reduce the vibration of the drilling tool, to protect the bit bearing, post teeth; to reduce the fatigue damage of the drill pipe, to prevent the chain pressure chain and improve drilling speed, to improve drilling design Parameters; will be helpful.
