| 摘 要： | 利用TerraSAR-X卫星2013-08~2014-08的17景雷达影像，采用小基线集（small baseline subset，SBAS）InSAR技术获取呼图壁(HTB)地下储气库（underground gas storage，UGS）运行期间的地表形变序列，并结合UGS注（采）气井口的压力数据，采用多点源Mogi模型，对HTB UGS的形变场进行模拟。结果表明，整个UGS区域的形变特征为非连续分布，形变与注（采）气压力变化具有较好的相关性；注（采）气期间沿卫星视线向(LOS)的形变峰值分别为10 mm和-8 mm；采用自适应前向搜索法，基于多点源Mogi模型初步模拟注（采）气期间的形变过程，当UGS的注（采）气平均气压为18 MPa和15 MPa时，LOS的形变可达7 mm和-4 mm，地表形变的大小与注（采）气井口密度有关；UGS的储气分布呈非均匀状态，即地下气库结构复杂多变。

| Abstract: | In this paper, 17 scenes TerraSAR-X radar images acquired from August 2013 to August 2014 are used by the small baseline subset (SBAS) InSAR method to obtain the surface deformation series during the operation of underground gas storage (UGS) in Hutubi (HTB). We combine these data with data from injection/production pressure wells, using multi-point source Mogi model to simulate the deformation field of UGS in Hutubi. The results show that the deformation characteristics of the whole UGS area is a discontinuous distribution, and the deformation peak value along satellite line of sight (LOS) is 10 mm and -8 mm during gas injection and gas production respectively. The retrieved deformation sequences conform to injection/production pressure changes very well. Based on the multi-point source Mogi model, we simulate the deformation process of HTB UGS and apply an adaptive forward search method to obtain the radius and depth of point source. The simulated results indicate that when the injection/production average pressure of HTB UGS is 18 MPa and 15 MPa, LOS deformation is up to 7 mm and -4 mm respectively; surface deformation is related to the density of gas injection/production wells. The UGS gas distribution is not uniform, indicating that the structure of underground gas storage is complex. |
