摘要
旋升式钻台是车装钻机的重要部件,不仅要承受很大的作业载荷,而且在起放钻台时栽荷也非常大,通常时前者做了强度校核,而后者的受力情况复杂。为保证钻井和修井作业的安全,采用工况模拟与应力测试相结合的方法,找到了旋升式钻台在起放过程中的危险工况及危险点,并提出了合理的解决办法,取得了很好的效果。
Being one of the important assembles,the swing drilling floor plays a key part in drilling or workover.It not only bears great working loads,but bears huge loads when being raised or laid down as well.Generally the former strength is calculated and verified,but the later is complex.In order to assure the drilling and workover safely,the author applied the stress testing method according to its actual use, found its dangerous working condition and its dangerous point,and provided the good resolution to the de- sign,and acquired good effect.
