【摘要】：金坛盐穴储气库采用单井双管油垫法分步式进行造腔。由于地下情况复杂,盐穴腔体在建造期间可能会遇到注水排卤井口泄漏、井筒泄漏、阻溶剂界面异常、造腔管柱故障及腔体泄漏等问题,若不能及时发现并采取应对措施,将会导致阻溶剂界面失控、造腔中断以及腔体体积损失等后果。金坛盐穴储气库通过在造腔实践中解决现场问题,形成了完善的造腔现场应对措施和监控体系,积累了处理造腔突发异常情况的经验,有效地保证了造腔的连续性,缩短了建腔周期,对后续盐穴储气库建设提供了理论依据和技术支持。
[Abstract]:Jintan salt cavern gas storage tank is constructed by single well and double tubing oil cushion method step by step. Because of the complicated underground conditions, the salt cavern cavity may encounter leakage of the well head of water injection and discharge of halogen during construction, wellbore leakage, and abnormal interface of resistance to solvent. If the failure of cavity string and leakage of cavity can not be detected in time and countermeasures can be taken, it will lead to the loss of control of the solvent resistance interface. Jintan salt cavern gas storage through the practice of cavity construction to solve the field problems, formed a perfect cavity site response measures and monitoring system. It accumulates the experience of dealing with the sudden abnormal situation of cavity making, effectively guarantees the continuity of cavity construction, shortens the period of building cavity, and provides the theoretical basis and technical support for the subsequent construction of salt cavern gas storage.
