摘要
将自升式钻井平台(简称钻井平台)桩腿简化为悬臂梁力学模型,研究了钻井平台横向振动特性,建立了较为简便的钻井平台横向振动周期、频率及振幅计算方法;利用得到的钻井平台横向振动特性计算式,对海洋石油钻井作业所用三桩腿、四桩腿钻井平台进行了横向振动特性值计算,并对振动周期、频率计算结果进行了分析;研究了钻井平台横向振动影响因素,并且提出了相应的改进思路及措施,这对指导海上钻井平台操船作业具有重要意义。
By simplifying the legs of jackup rig cantilever mechanics model, the paper studies transverse vibration characteristics of jackup and establishes the simple method for calcula rig ting the transverse vibration period, frequency and amplitude of jackup rig. The obtained calculation formula is used to calculate the values of transverse vibration characteristics for rigs with three and four legs utilized in offshore drilling and the calculated results of vibration period and frequency are analyzed. Through analyzing the influence factors on transverse vibration of the rigs, the relevant improvement ideas and measures are put forward, which has the important significance for direct the operation of jackup rig.
