摘要
中国盐穴储气库的建设历程划分为技术研究与探索、技术消化与形成、技术成熟与发展3个阶段,在建设过程中形成了老腔改造、腔体气密封测试、光纤测试油水界面以及高效注气排卤等多项特色技术。为保证盐穴储气库的安全稳定运行,提出了一套在注采运行过程中监测井口温度压力、地面沉降、腔体形态、井筒完整性在内的体系及方法。指出中国盐穴储气库建设存在造腔速度慢、老腔改造难、适建库址少等问题,现有工艺技术尚不能完全满足中国层状盐层地质条件下盐穴储气库建设的需要。针对盐穴储气库建设过程中面临的技术挑战,提出了相应的攻关研究内容,为中国盐穴储气库的技术发展指明了方向。
The construction course of salt-cavern gas storage in China is divided into three stages, i.e., technology research and exploration, technology digestion and formation, and technology maturity and development. In the process of saltcavern gas storage construction, a number of distinguished technologies are developed, such as old cavern rebuilding, gas leak detection of cavern, oil-brine interface monitoring based on optical fiber and high-efficiency gas injection debrining. In this paper, a complete set of system and technologies was developed to monitor wellhead temperature and pressure, ground subsidence, cavity shape and wellbore integrity in the process of injection and production to ensure the safe and stable operation of salt-cavern gas storage. The problems involved in the construction of salt-cavern gas storage were described, such as slow solution mining, difficult old cavern rebuilding and fewer sites available for gas storage building, and it was demonstrated that existing technologies can＇t meet the construction requirements of salt-cavern gas storage in layered salt beds in China. To cope with the technological challenges in the process of salt-cavern gas storage construction, a series of research contents were proposed correspondingly, and the technology development direction of salt-cavern gas storages in China was pointed out.
