摘要

虑修井工具的影响，开展修井船运动激励下修井隔水管系统动力学特性研究。基于梁理论建立了修井隔水管与修井工具的力学模型，施加了修井船运动、张紧系统及土壤等边界约束；使用间隙单元法建立了修井隔水管与修井工具的接触模型；基于有限元法与Newmark-β法建立了数值模型，对修井船不同运动下的修井隔水管系统动态响应进行了分析。结果表明，修井船升沉运动时，修井隔水管轴向位移与修井工具轴向位移差异显著；修井船纵荡时，修井隔水管与修井工具易发生规律性接触；修井船纵摇运动时，修井隔水管与修井工具运动几乎一致。

Abstract

The dynamic characteristics of workover riser system with workover tools under the excitation of workover vessel are studied. A mechanical model of workover riser and workover tool is established based on beam theory. The boundary constraints such as workover vessel, tension system and soil are applied to the mechanical model. The contact model is established by gap element method. A numerical model is established by finite element method and Newmark-β method. The dynamic response of workover riser system is analyzed. The results show that the difference between the axial displacement of workover riser and the axial displacement of workover tool is obvious when workover vessel is in heave motion. The workover riser and workover tools are prone to contact regularly when workover vessel is in surge motion. The movement of workover riser and workover tool is almost the same when workover vessel is pitching.
