摘要
针对具有小区域特征的地表非线性形变对于合成孔径雷达干涉测量(InSAR)技术从监测点密度和监测精度都提出了更高的要求这一现状。该文基于SBAS-InSAR的技术原理,提出了一种基于高效率、低成本的地表非线性形变时序监测方法,并以柴达木盆地一处油田为研究对象,获取了研究区2007年初到2010年中期的形变结果,表明4处采油点中1处下降、3处隆升,隆升主要由注水引起。研究证明:SBAS-InSAR技术在地表非线性形变时序监测方面具有较强能力,提取的形变成果可为生产单位和政府部门分析决策提供科学依据。
Aiming at the current status that the nonlinear deformation of the surface with small regional features require higher density and precision of monitoring points for interferometric synthetic aperture radar(InSAR)technology?Based on the principle of small baseline subset InSAR(SBASInSAR),a high efficiency and low cost time series monitoring method for surface nonlinear deformation was proposed.Taking an oil field in Qaidam Basin as the research object,deformation results of the research area from 2 0 0 7 to 2 010 were obtained.All the four oil production points showed obvious time series deformation,of which one fell and the other three uplifted.The uplifting was mainly caused by water injection.The paper proves that SBAS-InSAR technology has strong capability in time seriesmonitoring the surface nonlinear deformation,and the obtained deformation results can provide a basis for the analysis and decision-making of production units and government departments.
