- Abstract
The research preliminarily demonstrated the feasibility of building natural gas storage in abandoned salt caverns in Tai' an from the geological point of view. According to the characteristics of high-proportioned interlayers in Tai'an salt mine, a new model of underground space utilization of salt cavern一the model of sediment interspace utilization (Tai'an model) was put forward. The feasibility of building gas storage using abandoned salt caverns was analyzed from two aspects of stability and permeability. The permeability, porosity, scanning electron microscope (SEM) results of the interlayer and the thickness of the top retained salt layer were used to demonstrate the sealing performance. The stability of salt cavern gas storage was demonstrated by the proportion of sediment filling and the distribution of surrounding faults. Based on the investigated salt mining information, the preliminary analysis showed that the short-term potential gas storage scale could reach 1. 86 billion cubic meters, and the long-term potential gas storage scale could reach 7.5 billion cubic meters.
