摘要：

钻柱升沉补偿装置是海洋钻井设备的重要组成部分, 在钻井作业中, 可补偿平台的升沉运动, 在保证井底钻压稳定的同时, 保障了钻井效率以及钻头和钻杆的使用寿命, 提高钻井安全性.目前, 我国钻柱升沉补偿装置需要从国外进口, 且价格十分昂贵, 因此, 研发具有我国自主知识产权的海洋钻井平台升沉补偿装置势在必行.在国内外升沉补偿装置相关资料的基础上, 对现有钻柱升沉补偿装置的结构,工作原理及应用情况进行分析, 并结合现用游车大钩升沉补偿装置在使用过程各种升沉补偿方式的优缺点, 提出了新型升沉补偿装置的设计方案, 优选出齿轮齿条式作为升沉补偿装置的新型补偿方式.对新型的齿轮齿条式补偿装置进行运动分析, 为新型升沉补偿装置的结构设计和仿真分析提供参考.

Abstract:

The drill string heave compensation system is an important part of offshore drilling equipment. During the operation, it can compensate heave motion of the platform, ensure a stable bottom hole pressure while drilling, keep drilling efficiency, protect the life of the drill bit and drill pipe, and improve drilling safety. At present, the drill string heave compensator device needs to be imported, and the price is very expensive, so the development of heave compensation system for offshore drilling platforms with our own intellectual property is imperative. On the basis of heave compensation device-related information and analyses on the structure, working principle and application of the existing drill string heave compensation system, considering the advantages and disadvantages of different heave compensation methods in practical operations, the new design scheme is proposed for heave compensation device. The rack-and-pinion scheme is selected for the new heave compensation device after comparison. Motion analysis on the rack-and-pinion device provides a reference for the structural design and simulation analysis of new heave compensation systems.

Key words: offshore drilling equipment, swim car, hook, heave compensation, equipment design, motion analysis
