摘　　要：涡激振动引起的应力和疲劳损伤是影响钻井隔水管作业安全的重要因素,设计阶段往往采用严苛的海洋环境参数,虽然可以保证系统安全,但是却会影响钻井时效。本文利用加速度监测装置对南海X-1井进行了隔水管的涡激振动监测,通过对监测数据的频谱分析,发现隔水管产生涡激振动的频谱具有明显的锁频特征,并且涡激振动并不存在于整个作业过程,因此在实际作业阶段隔水管参与涡激振动的模态最高阶次存在超过设计预期水平的可能性。本文提出根据实测数据预测和评估钻井隔水管涡激振动响应的方法,对保证隔水管系统作业安全具有重要意义。Stress and fatigue damage caused by vortex induced vibration(VIV)are important factors affecting the safe operation of drilling riser.Strict marine environmental parameters are often adopted in the design stage,which can ensure the safety of the drilling system,but will affect the drilling efficiency.In this paper,an acceleration monitoring device is used to monitor the VIV of the riser in well X-1,South China Sea.Through spectrum analysis of the monitoring data,it is found that the frequency spectrum of the VIV of the riser has obvious frequency locking characteristics,and the VIV does not occurred in the whole operation process.Moreover,the highest order of riser involved VIV modal has the probability of exceeding the expected level in actual operations.The method proposed in this paper to predict and evaluate the VIV responses of drilling riser based on the measured data is of great significance to the operation safety of riser system.
