摘要:

中国地下储气库经历了20余年的发展,由20世纪末的起步摸索期进入目前的快速发展阶段,亟需建立一套适用于中国复杂地质条件与大吞大吐、交变应力运行工况下的储气库地质理论。在借鉴国外储气库和总结中国储气库建设运行经验的基础上,提出了储气地质体与储气库地质理论的概念,创建了以储气地质体为评价对象、以储气圈闭构造地质学、储气空间储层地质学、交变载荷岩石力学、孔隙空间动用渗流力学等为主要内容的储气库地质理论体系,指导了地下储气库的选址评价、建库方案和扩容达产调整方案编制,对加快中国储气库建设,保障储气库长期安全高效运行意义重大,应用前景广阔。

Abstract:

Underground gas storage in China has experienced more than 20 years of development, and now it has entered the rapid development stage from the trial stage at the end of the 20th century. It is urgent to establish a set of geological theories for underground gas storage applicable under complex geological conditions in China and the operational conditions such as large-scale throughput and cyclic loading-unloading stress. Based on referring to and summarizing the international and domestic experience of constructing and operating gas storage, respectively, this paper proposes the concept of geological body for gas storage and the geological theory of gas storage. Taking the geological body for gas storage as the evaluation object, the geological theoretical system established in this study mainly involves the structural geology of gas storage trap, reservoir geology of gas storage space, rock mechanics under cyclic loading-unloading condition, porous flow mechanics of pore space utilization; it helps guide the site evaluation and prepare programs for building gas storage and adjusting the capacity expansion of underground gas storage. It is of great significance to accelerate the construction of gas storage in China and guarantee the long-term safe and efficient operation of gas storage, and thus has broad application prospects.

Key words: underground gas storage, geological body for gas storage, structural geology of gas storage trap, reservoir geology of gas storage space, rock mechanics under cyclic loading-unloading condition, porous flow mechanics of pore space utilization
