浮式钻井平台补偿系统的建模与分析

摘要

在前人研究的基础上对浮式钻井平台钻柱主动补偿系统的关键装置建立数学模型。对主动补偿系统重要组成部分———动力部分和控制部分进行分析，在理论分析的基础上提出对这两部分的改进建议，为进一步提高升沉补偿系统的能力及精度提供了理论依据。%On the basis of previous research on the drilling string heave compensation system for floating drilling platform , the mathematical model of a drill string heave compensation system was set up .The power part and control part of drill string heave compensation system was analyzed .Based on theoretical analysis ,some suggestion to further improve the heave compensation system was put forward ,in order to provide theoretical basis for the improvement of the compensation ability of the system .
