摘　　要：针对辽河油田区地表形变特征及变形趋势不明的问题,利用SBAS-InSAR和MSBAS-2D技术对该区2019—2021年地表多维形变特征进行监测,并将Okada矩形位错模型用于典型油田开采区储层参数反演。结果表明:研究区曙光采油厂、欢喜岭采油厂和锦州采油厂均存在因石油开采导致的地面沉降,其中曙光采油厂两年内累积形变达-330 mm,沉降漏斗最大垂直形变和水平位移分别为-150和55 mm,其形变量之比约为3∶1。利用Okada矩形位错模型反演曙光采油厂区域油层深度为1642.22 m,与实际油层深度接近,适用于该区域油田储层参数反演。此外油气开采与周缘的地震事件无明显的相关关系。该方法能较为全面地监测辽河油田区地表形变特征,可为该区油气生产及沉降灾害防治提供参考。In order to solve the problem of unclear surface deformation characteristics and deformation trend in Liaohe Oilfield Area,this paper uses SBAS-InSAR technology and MSBAS-2D technology to monitor the multidimensional surface deformation characteristics from 2019 to 2021 in this area,and uses Okada rectangular dislocation model to invert reservoir parameters in typical oilfield exploitation areas.The results show that Shuguang Oil Production Plant,Huanxiling Oil Production Plant and Jinzhou Oil Production Plant in the study area all have ground subsidence caused by oil exploitation.The cumulative deformation in Shuguang Oil Production Plant reaches-330 mm within two years;the maximum vertical deformation and horizontal displacement of the settling funnel reach-150 mm and 55 mm respectively;and the ratio of deformations is about 3∶1.Okada rectangular dislocation model is used to reverse the reservoir depth in Shuguang Oil Production Plant and the reservoir depth is 1642.22 m,which is close to the actual reservoir depth,showing that Okada rectangular dislocation model is suitable for reservoir parameter inversion in this area.Furthermore,there is no obvious correlation between oil and gas exploitation and surrounding seismic events.The proposed method can monitor the surface deformation characteristics of Liaohe Oilfield Area comprehensively and thus can provide reference for oil and gas production and settlement disaster prevention in this area.
