摘要
根据地裂缝改变层状地层的几何结构,破坏地层界面的连续性,引起地球物理场的变化等特征,应用三维地震勘探方法探查地裂缝。以长江三角洲WYGA地区三维地震勘探为例,论述了三维地震探查地裂缝数据采集方法、资料数字处理、资料解释等问题,结果显示,地质效果良好。
The ground fissure have changed geometric structure of strata, caused the earth physics field changed and destructed strata interface continuity,that provides the geology premise for 3D seismic exploring and surveying the ground fissure. Taking an example of the 3D seismic exploring and surveying the ground fissure in certain place the delta of Yangtze River, the paper clarified the problem of the 3D seismic data acquisition＇s method, the data processing, the data interpretation etc., and obtained ef- fective geology result.
