摘　　要：为了更精确地评价隔水导管涡激效应,简化了隔水导管受力模型,并建立计算方法,结合现场工况对24in隔水导管进行了理论分析,综合静力与波流涡激振动分析结果,在满足海况条件的基础上,如果以50年为开发周期的油田,24in壁厚1in隔水导管在强度方面可以满足要求对现场作业,对井口稳定性分析具有一定的指导意义。In order to more accurately evaluate the vortex-induced effect of the riser,the stress model of the riser was simplified,and a calculation method was established.The theoretical analysis of the 24 in riser was carried out in combination with field conditions,and the static and wave vortex-induced vibration analysis was integrated.As a result,on the basis of meeting the sea conditions,if an oilfield with a development period of 50 years,the 24 in wall thickness 1 in riser can meet the requirements in terms of strength.It has a certain guiding significance for wellhead stability analysis.
