摘　　要：对钻机平台进行振动测试与激励源的分析是平台结构振动的基础。目前,对塔里木油田超深井钻机平台的振动源的相关研究较少,对沙漠油田的风沙振动影响的情况不明。以塔里木油田热瓦普区热普5号井钻机平台为测试对象,对平台X,Y,Z方向进行了振动测试与振动信号的采集,并进行了振动信号的频谱分析。结果表明:在超深井钻井时,空气压缩机等钻井动力系统对钻机平台的振动影响最大,振动的位移主要为Z方向的垂直振动,振动频率为17.5,82.3Hz时振动的幅值达到最大,分别达到1.203,1.16 mm。同时,沙尘暴风力对钻机平台的振动也有较大的影响,当风振频率在11.5 Hz时,Z方向振动幅值达到0.463mm。Test of vibration and analysis on excitation source in drilling platform are the foundation of platform structure vibration. However,the vibration source in the Tarim oilfield ultra deep well drilling platform of related research is less,the influence of wind vibration of desert oilfield is unknown. Number five well rig in Heatgeneral area of Tarim oilfield is used as test object, vibration testing and vibration signal are collected in X, Y, Z directions of platform, frequency analysis on vibration signal is realized. The results show that air compressor and other drilling power system has a powerful vibration influence on the drilling platform, displacement is mainly vertical vibration in Z direction, and when the vibration frequency is 17.5 Hz and 82.3 Hz, the amplitude will reach the maximum value to 1. 203 mm and 1.16 mm. At the same time,storm wind have an great effect on the vibration of drilling platform,when the wind vibration frequency is 11.5 Hz, the vibration amplitude in Z direction reach to 0. 463 mm.
