摘要:

中国石油西南油气田公司川东北高含硫气田项目合作开发一年有余,目前已全部进入详细设计阶段。根据前期的设计讨论,川东北项目井口安全控制系统的设计思路与国内外常规的井口控制系统设计思路存在较大变化,同时也存在较大争议;本文从设计角度出发,阐述国内外常规的井口控制系统设计思路,也结合目前项目井口安全控制系统的设计方案与常规方案进行对比与分析,并推荐适合项目的最佳设计方案。

Abstract:

The cooperative development of CDB high-sour gas field has lasted for more than 1 year.Currently,it is in the stage of Detailed Design (DD).According to the design discussion in the phase of preliminary design,the design of CDB wellhead control system is of great differences from oversea design philosophy,and resulting in great disagreement.The typical wellhead safety control system design proposals both oversea and domestical are presented,meanwhile,the current wellhead control design is compared with the conventional ones.The optimal design proposal fitting for this program is recommended.
