发布时间：2018-09-18 18:55
【摘要】：储气库是天然气储存和调峰的重要方式,主要有枯竭油气藏、含水型、盐穴和废弃矿藏等四种储气库类型。枯竭型气藏改建地下储气库具有技术成熟、投资较低等优势,论文对枯竭型气藏改建储气库相关配套技术进行研究,将地面工程配套技术作为主要研究内容,研究了注气工艺、采气工艺、注采气辅助配套工艺,对注气压缩机和集输管线的设备选型和能力计算、优化配置方法进行了分析,对储气库建设与运营经济效益分析方法进行了研究。以华北油田文23枯竭型凝析气藏改建地下储气库的工程建设为范例,对储气库地面配套工艺技术、注气设备选型、集输管线确定、建设运营经济效益等方面进行了实例计算和分析。针对文23储气库的情况,提出了井口注甲醇配合加热炉加热的水合物预防工艺,膨胀制冷和外加冷源制冷脱烃处理工艺,采用电力驱动的往复式压缩机注气配套设备组合,该方案比较适用于文23这一类平原地区储气库。论文使用的储气库数据来自文23储气库,部分设计数据经过现场实际应用,对工程建设的顺利开展起到了一定的积极作用。
[Abstract]:Gas storage is an important way of natural gas storage and peak-shaving. There are four types of gas storage: depleted reservoirs, water-bearing reservoirs, salt caverns and abandoned mineral deposits. The reconstruction of depleted gas reservoirs into underground gas storage has the advantages of mature technology and low investment. In this paper, the related supporting technologies of gas storage reconstruction in depleted gas reservoirs are studied. The surface engineering supporting technology is taken as the main research content, and the gas injection technology is studied. This paper analyzes the equipment selection and capacity calculation of gas injection compressor and gathering pipeline as well as the optimization configuration method, and studies the economic benefit analysis method of gas storage construction and operation. Taking the engineering construction of Wen23 depleted condensate gas reservoir in Huabei Oilfield as an example, the surface matching technology, gas injection equipment selection and gathering and transporting pipeline of gas storage reservoir are determined. The economic benefits of construction and operation are calculated and analyzed by examples. In view of the situation of Wen 23 gas storage, this paper puts forward the hydrate prevention technology of methanol injection at the wellhead and heating of heating furnace, expandable refrigeration and external cold source refrigeration deshydrocarbon treatment process, and adopts the combination of electric power driven reciprocating compressor gas injection matching equipment. This scheme is more suitable for gas storage in plain areas such as Wen 23. The gas storage data used in this paper come from Wen23 gas storage, and some of the design data have been applied in the field, which has played a positive role in the smooth development of engineering construction.
