【摘要】：深水钻完井工程设计存在水文地质条件恶劣、作业成本高昂等一系列设计难点,这在一定程度上制约着我国深水油气田开发的进程。基于钻完井工程设计的流程及特点,以南海某深水油田的钻完井设计方案为例,选择井眼轨迹及井身结构设计、工作液设计、钻柱及钻具组合设计、井控工艺设计等主要的钻完井工程设计部分,进行了设计理念以及设计结果的分析。得出了深水钻完井工程设计适宜采用的关键技术以及基本设计思路,提出了简化井身结构、简化钻具组合、注重浅层气井控、采用批次作业等针对性的设计建议,能够为深水钻完井工程设计提供有益借鉴。
[Abstract]:There are a series of difficulties in the design of deep water drilling and completion engineering, such as poor hydrogeological conditions and high operating cost, which to some extent restrict the development process of deep water oil and gas fields in China. Taking the drilling and completion design scheme of a deep water oil field in the South China Sea as an example, the main drilling and completion engineering design parts, such as hole trajectory and wellbore structure design, working fluid design, drill string and drill pipe combination design, well control process design, etc., are selected. The design concept and design results are analyzed. The key technologies and basic design ideas for the design of deep water drilling and completion engineering are obtained, and the simplified wellbore structure, the simplified drilling tool combination, and the emphasis on shallow gas well control are put forward. Using batch operation and other targeted design suggestions can provide useful reference for deep water drilling and completion engineering design.
