| 摘 要： | 利用呼图壁地下储气库地质、地球物理资料，建立呼图壁地下储气库三维有限元模型。利用储气腔体压力变化对储气库进行边界约束，用一整个观测周期水准模拟数据结果对几何模型进行可靠性评定。结果显示，储气库整个注、采气过程类似于地球呼吸，在注气过程中地面点由于压力作用呈现出向外膨胀的趋势，在采气过程中地面点点位向着储气层垂直向上的盖层集中运动，呈现出向内塌陷的趋势。

| Abstract: | In this paper, the three-dimensional finite element model of the underground reservoir of Hutubi wall is established using the geological and geophysical data of Hutubi underground gas storage. The boundary of the gas storage model is constrained by the pressure change of the gas storage chamber. We simulate the data of the period to evaluate the reliability of the geometric model. The results show that the gas injection is similar to the respiration of the earth during the whole gas injection process and the gas production process. During the gas injection process, the ground point exponentially expands due to the pressure. During the process of gas production, the ground point of the ground surface is concentrated toward the vertical upward cover of the gas storage layer, showing a tendency to collapse inward. |
