摘要
针对石油开采所致形变具有周期长、连续性强及范围广,常规形变监测方法无法满足高效监测需求的问题。时序差分合成孔径雷达干涉具有监测范围广和效率高的优势。采用干涉点目标分析技术与69景Sentinel-1A SLC数据对大宛齐油田进行地表形变监测及时序分析。结果显示,2016年2月—2018年12月间大宛齐油田年均形变速率在-81~49 mm/a,开采区存在两处明显沉降漏斗与两处明显隆起,最大沉降面积达5.8 km^(2),除此外无明显形变。GPM降水数据与时序形变量的叠加分析显示,大宛齐油田形变具有明显季节性特征,形变与油田生产及地质条件具有相关性。
The deformation caused by oil exploitation has the characteristics of long period,strong continuity and wide range.The conventional deformation monitoring methods can not meet the needs of efficient monitoring.Time series differential synthetic aperture radar interferometry has the advantages of wide monitoring range and high efficiency.The interferometric point target analysis technology and 69 Sentinel-1 A SLC data were used for surface deformation monitoring and time series analysis of Dawanqi oilfield.The results show that from February 2016 to December 2018,the average annual deformation rate of Dawanqi oilfield is-81~49 mm/a.There are two obvious subsidence funnels and two obvious bulges in the mining area,and the maximum subsiding area is 5.8 km^(2),except which there is no obvious deformation.The superposition analysis of GPM precipitation data and time series deformations shows that the deformation of Dawanqi oilfield has obvious seasonal characteristics,and the deformation is related to oilfield production and geological conditions.
