大港地区板中南储气库运行压力界限研究
|
摘要
地下储气库是调峰保供和天然气管网优化管理的有效手段,也是国家能源安全的重要保障。目前,中国地下储气库建设在工作能力、建库技术等方面取得了可喜的进展,但同时也面临诸多问题。通过对大港地区板中南储气库盖层封闭能力和断层稳定性定量评价研究,合理确定地下储气库的运行压力界限,为提高地下储气库运行效率、提高气井注气能力、增强储气库运行安全提供必要的理论支撑与实践指导。通过对大港地区板中南储气库运行压力界限研究,可以探索改善气库科学、安全、高效运行的一套行之有效的方法,并推广应用到其它类似的气库。
The underground gas storage will play an important role in domestic natural gas peak shaving safety and supply guarantee. China has made progress in operation pressure and building storage,but we will also face a number of problems in evaluating capillary sealing and hydraulic sealing of cap and the fault stability of Banzhongnan underground gas storage. We are confirming its operation pressure limit to provide theoretical support and practice guidance for enhancing operational efficiency and operational safety. Through the study on the operation pressure limit of Banzhongnan gas storage in Dagang area,we can explore a set of effective methods for improving the scientific,safe and efficient operation of gas storage,trying to extend to other similar underground gas storage.
