Therefore, it is important to study the tubular mechanical behavior under loading conditions in the drilling operation, the deepwater environment and the vessel movements for safety of the deepwater drilling operation without riser. The transverse and longitudinal bending deformations, the longitudinal vibration of the drilling tubular string and the landing string design method for the deepwater drilling operation without riser are discussed in this paper. The variations of the tubular string deformation and the longitudinal vibration are analyzed by considering the relevant influencing factors. Based on the above analysis, the complicated engineering problems related to the tubular mechanics in the deepwater drilling operation without riser are simplified to be considered in the actual design and control. The results show that it is dangerous for the tubular string in the deepwater drilling operation without riser to work under the conditions of high or low axial tension force, deep water, severe vessel offset or heave and high speed current. The operation modes and the environment loads should be taken into account for the tubular string design and the strength check in the deepwater drilling operation without riser., authors=GAO Deli¹, ZHANG Hui^1,2, authorsList=GAO Deli;ZHANG Hui;, authorCompany=1.

articleAbstract=无隔水管深水钻井作业是深水钻井的关键环节之一,管柱的力学行为十分复杂。本文阐述了无隔水管深水钻井管柱的纵横弯曲变形力学模型、纵向振动力学模型及无隔水管深水钻井送入管柱设计与强度校核方法等,分析了作业管柱变形及运动的主要影响因素和规律,提出了解决这类复杂工程问题的简化思路。结果表明,作业管柱的轴向拉力过大或过小、海水深度大、平台偏移或升沉振动幅度过大以及海流流速快等因素对管柱的强度安全具有显著影响。在无隔水管深水钻井作业管柱强度设计与校核时,应充分考虑管柱的作业工况及环境载荷的影响。,
