浮式海洋钻井钻柱对大钩位移的响应分析
Response analysis of drill string for hook displacement in floating offshore drilling
摘要
Abstract
The heave motion of offshore drilling platform has a great impact on the drill string, weight on bit and drilling operations.A dynamic model of drill string system for floating drilling platform was developed.Using series method and mechanical vibration theory, the motion response of drill string system was obtained, and then the mathematical formula expressing the relationship between the hook displacement and the weight on bit variation was derived.The allowed values of hook shift were calculated by Matlab under the given lengths of drill string.The calculation results provide the design basis for the heave compensation equipment development of floating drilling platform.The results can be used as the reference of design objectives and performance evaluation of heave compensation system.关键词
