| 摘 要： | 湿气高精度贸易计量是国际性难题,因为湿气气相部分含有重烃、游离水,与经过处理后的外输气(干气)组分相差较大;湿气液相部分含烃(溶解气)常规仪表无法达到贸易计量精度,而带压化验(4万元/次)费用过高,降低效益。中海油南海某气田(中海油自营)水下井口物流经20km海管回接至原有YC13-1平台(中外合资)后为了降底投资,提高效益必须面对湿气贸易计量问题,此外还要解决来自海管段塞流对计量精度的冲击。本文将介绍湿气能量贸易计量解决方案,在中海油南海某气田开发项目中的应用、技术先进性及效益。

Research and Application of Wet Gas Custody Transfer Metering In China Offshore Oil Industry |
| |
| Abstract: | The wet gas custody transfer (high accuracy) metering is not an easy task for the international oil and gas market. A central problem is that gas and hydrocarbon liquids, free water co-exist in the gas phase and dissolved gas and water and the hydrocarbon liquids co-exist in the liquid phase. The components compared with the dry gas or liquid treated are quite different. These will cause a large uncertainty. The wet gas from subsea wells of the Nanhai new gas field (by CNOOC) transfer to the platform of the... |
