Ground Deformation Revealed by Sentinel-1 MSBAS-InSAR Time-Series over Karamay Oilfield, China

流体萃取或注射到地下水库可能会导致地面变形，表现为沉降或隆起。过度变形可能会威胁到油田及其周边地区的基础设施，甚至可能诱发地震。因此，造成的石油生产活动表面变形监测是安全生产油田和周围的基础设施的安全性评估的重要。克拉玛依油田是中国主要的石油和天然气田之一。在这项研究中，我们采取新疆克拉马伊油田作为案例研究，以检测由地下流体喷射表面变形。 32升（路径114）和下行34（路径165）的定点-1A图像轨道跨越年3月2017年至2018年八月，使用在使用MSBAS-干涉SAR方法克拉马伊油田导出垂直和水平变形。所观察到的二维变形在该区域显示出显著垂直和东 - 西变形。最大隆起和水平速度为约160毫米/年和65毫米/年，分别。我们也仿照使用均匀弹性半空间位错模型典型的变形区之一。
