高酸性气田现场仪表典型安装方案设计优化

Typical installation scheme design optimization of field instruments in high sour gas field

川东北高含硫气田项目已全部进入详细设计阶段。为了减少高酸性气田现场仪表可能存在的泄漏点,实现本质安全,清洁高效地开发高酸性气田,在常规的仪表安装设计方案的基础上,结合雪弗龙项目及普光气田的经验对现场仪表典型安装方案进行了设计优化,最大可能地减少仪表安装上的漏点,方便运行维护。该文从设计角度出发,将国内常规的仪表安装方案设计与目前项目现场仪表典型安装设计方案进行对比,并推荐出适合高酸性气田项目的设计优化方案。

CDB high sour gas field project has stepped into detail design phase completely.In order to reduce the potential leakage point,realize intrinsic safety and develop high sour gas field environmental-friendly,combined with the experience of Chevron project & Puguang gas field,CDB engineering project design team optimizes the designing scheme of field instrument typical installation on the base of regular instrument installation scheme to minimize leakage and realize maintenance convenience.The national conventional instruments installation scheme and current field instruments typical installation scheme were compared from the view of design,and the optimization designing scheme suitable for high sour gas field project was recommended.
