新型RMR钻井系统泥浆返回管线海底锚泊方案

摘要

无隔水管海底泥浆举升钻井（R MR ）是应对深水复杂环境下表层钻井的有效方案。在深水R MR系统配置方案研究的基础上，针对无隔水管泥浆举升钻井泥浆返回管线的工况要求，对当前常用海底锚泊方案进行分析，提出适合深水条件的泥浆返回管线海底锚泊方案，并对该方案进行原理分析和结构设计。%The riserless subsea mudlift drilling is an effective solution to deal with the difficulty of surface drilling in complicated deepwater environment.Based on the research of system configura-tion of deepwater riserless mudlift drilling,according to the condition requirement of the mud re-covery line,the current commonly used anchorage scheme was analyzed,and the subsea anchorage scheme of mud recovery line was proposed,which is suitable for the condition of deepwater.The scheme principle was analyzed to accomplish the structure design of the scheme.
