油气田中心处理站能量保障分析

Energy Support Analysis of Central Processing Station of Oil and Gas Field

油气田中心处理站是对各计量站或接转站来液进行集中处理的场所,主要处理流程包括油气水分离、原油脱水处理、原油稳定、轻油回收、天然气净化、采出水处理和回注、配套发电机等,特征是设备多、流程复杂,且能源消耗直接影响整个集输系统,特别是伴随着油田生产的进行,油中含水量逐渐增加,伴生气量逐渐降低,能量消耗结构发生变化,这种影响更明显。因此,有必要研究和分析油气田中心处理站全生命周期内的能量平衡,确保油气田中心处理站的长期、高效、平稳运行,同时也能指导生产管理者按最优化的运行参数组合管理生产。本文立足某国外油气田工程,从多方面对中心处理站进行能量平衡分析,保障其在全生命周期内的安全、平稳运行。

The central processing station of oil and gas field is a place for centralized treatment of the liquid from each metering station or transfer station.The main processing processes include oil-gas water separation,crude oil dehydration treatment,crude oil stabilization,light oil recovery,natural gas purification,produced water treatment and reinjection,supporting generators,etc.,characterized by multiple equipment and complex processes,and energy consumption directly affects the entire gathering and transportation system.Especially with the progress of oil field production,the water content in oil gradually increases,the associated gas gradually decreases,and the energy consumption structure changes,and this effect is more obvious.Therefore,it is necessary to study and analyze the energy balance in the whole life cycle of the oil and gas field central processing station,to ensure the long-term,efficient and smooth operation of the oil and gas field central processing station,and to guide the production manager to manage the production according to the optimal combination of operating parameters.Based on a foreign oil and gas field project,this paper analyzes the energy balance of the central processing station from various aspects to ensure its safe and stable operation in the whole life cycle.
