在采气期,油藏型储气库采出的天然气会携带少量黑油进入下游低温装置,导致黑油凝固析出,造成设备、管线堵塞,影响装置安全运行。为解决油藏型储气库采出天然气携带黑油的问题,避免析出黑油影响储气库采气装置的正常运行，经分析研究设置旋流分离器+过滤分离器两级过滤除黑油流程,从天然气中过滤出99.9%以上直径大于1 μm的液滴,减少天然气携带黑油进入后续低温处理装置,提高了冬季调峰、储气库供气的安全性及可靠性。两级过滤除黑油技术在中国首座油藏型储气库中已成功应用,为后续同类型储气库的建设提供了经验借鉴。同时,根据除黑油过滤机理,研发出一体化精细除黑油分离器,此分离器能高效地提高油藏型储气库除黑油的效果,建议将分离器设置在采气装置空冷器后。一体化精细除黑油分离器的设置可为后续同类型储气库设计提供指导。
During the production phase of oil reservoir type gas storage, the natural gas carries over a small amount of black oil droplets to the downstream low-temperature treatment facilities, resulting in black oil solidification and precipitation, causing equipment and pipeline blockage and affecting the safe operation of the production facilities. After analysis and research, the research team set up a two-stage black oil filtering and removal process, namely cyclone separator plus filter separator, to filter off 99.9% of liquid droplets larger than 1μm in diameter from natural gas, thereby reducing the black oil carry-over into the downstream cryogenic processing facilities, and improve the safe operation and reliability of gas supply from the peak-shaving gas storage in winter. As the well known first oil reservoir type gas storage in China, the successful application of the two-stage black oil filtering and removal technology provides experience and valuable reference for the subsequent development of gas storage of the same nature. At the same time, according to the filtration mechanism of black oil, a new integrated ultra-fine black oil droplet separator was developed. This separator will effectively improve the black oil droplet removal efficiency of gas re-produced from reservoir type gas storage. It is suggested that the separator be installed downstream of the air cooler of the gas production facilities. The development of integrated ultra-fine black oil droplet separator as presented in this paper can provide guidance for the future process design and engineering of the same type of gas storage.
