摘要: 采用SBAS-DInSAR技术获得了克拉玛依油田的年平均形变速率和长时序形变,利用兼顾均值和标准差的方法提取了高形变区,计算了由西向东和由北向南的形变梯度,分析了等时间间隔的累计形变量、高形变区所占比例、特征点沉降趋势。结果表明,研究区的形变区与石油开采区域有较高的一致性且形变多与油田开采及注水注气相关;形变在空间上表现为非均匀性,在时间上表现为非线性;研究区形变总体趋势仍在变化;特征点的累计形变表现为多样性,这与地面地物有着密切的相关性。SBAS-DInSAR技术对于广域长时序非线性的油田形变监测具有较好的可行性,可提供有效的技术支撑。

Abstract: The authors obtain the annual average deformation rate and long time series deformation of the Karamay Oilfield with SBAS-DInSAR and then determine the high deformation area by taking into account the mean and standard deviation. By analyzing the results of the deformation gradients from west to east and from north to south, the cumulative deformation variables of equal time interval, the proportions of high deformation areas and the deformation trend of the characteristic points, it is found that the deformation area is highly consistent with the oil exploitation areas, and the deformation is more likely to take place during oil production and water and gas injection. Besides, the deformation is inhomogeneous in space and nonlinear in time and its overall trend in the study continues to change. Finally, the diversity reflected in the cumulative deformation of feature points is closely related to the surface features. The above results show that it is of great feasibility to apply SBAS-DInSAR to monitor long term nonlinear oilfield deformation.
