【摘要】：悬臂梁式自升式钻井平台在海洋钻井工作中的应用越来越多,悬臂梁结构的设计关系到平台的整体作业能力。本文对悬臂梁整体进行了结构设计,考虑风载、钻井组合载荷、钻台井架自重、悬臂梁自重以及悬臂梁堆场载荷等对悬臂梁结构的影响而对悬臂梁进行受力分析,其中钻井组合载荷随钻井中心位置不同而不断变化,通过其与其他载荷之间的数量关系计算出不同井眼中心的钻井组合载荷,对钻井工作的顺利进行有重要指导作用。为方便修改悬臂梁结构得到满意的设计结果,利用APDL语言可建立悬臂梁参数化模型,借助Visual Basic 6.0软件开发出悬臂梁结构从建模到有限元分析结果提取的工具软件,通过可视化的参数输入不断修改模型,对悬臂梁结构主要参数的优选起到重要的辅助作用,可迅速生成一套悬臂梁结构方案。根据悬臂梁主体结构设计的结果,以悬臂梁受力的理论分析为依据,对悬臂梁的承载基座进行了结构设计与强度校核,使悬臂梁结构强度满足安全要求。考虑到悬臂梁纵向移动的需要,对悬臂梁最大纵移驱动力进行计算。以最大驱动力为依据设计了悬臂梁的纵向移动驱动系统。以液压驱动为基础对与液压缸连接的推移部件进行了新的结构设计,完成了滑移系统的整体布置和设计。
[Abstract]:Cantilever beam jack-up drilling platform is more and more widely used in offshore drilling. The design of cantilever beam structure is related to the whole working ability of the platform. In this paper, the structure design of cantilever beam is carried out, considering wind load and combined drilling load. The influence of the weight of the Derrick, the weight of the cantilever beam and the load on the stacking field of the cantilever beam on the cantilever beam structure are analyzed. The combined load of the drilling rig varies with the location of the drilling center. Through the quantitative relationship between them and other loads, the combined load of drilling at different borehole centers is calculated, which plays an important guiding role in the smooth drilling operation. In order to facilitate the modification of cantilever beam structure, satisfactory design results are obtained. The parametric model of cantilever beam can be established by using APDL language, and the tool software of cantilever beam structure from modeling to finite element analysis can be developed with the aid of Visual Basic 6.0, and the model is constantly modified by visual parameter input. It plays an important role in the optimization of the main parameters of the cantilever beam structure, and can quickly generate a set of cantilever beam structure scheme. According to the results of the design of the main structure of the cantilever beam, the theoretical analysis of the cantilever beam force is taken as the basis. The structural design and strength check of the bearing base of the cantilever beam are carried out to make the structural strength of the cantilever beam meet the safety requirements, taking into account the need of the longitudinal movement of the cantilever beam. The maximum longitudinal driving force of cantilever beam is calculated. Based on the maximum driving force, the longitudinal moving driving system of cantilever beam is designed. The overall arrangement and design of the slip system are completed.
