在重庆涪陵地区实施的焦石坝三维地震勘探，采用宽方位、高覆盖的束状正交三维观测系统，三维叠加剖面质量显著提高，有力支持了勘探部署。对该观测系统实施后的实际资料进行分析，认为焦页4井附近志留系龙马溪组页岩存在地震方位各向异性；同时，该观测系统基本满足方位各向异性研究的要求，可以利用宽方位、高覆盖的三维数据进行方位各向异性裂缝检测研究。

In the 3D seismic project implemented in Fuling area,the geometry has wide -azimuth and high fold,and the 3D stacked section quality has been significantly improved,therefore strongly supportting the deployment of drilling. Throgh the analysis of 3D seismic data,we realized that Longmaxi shale exists seismic azimuthal anisotropy,and the 3D seismic geometry basically meets the requirements of azimuthal anisotropy studies.So we can use the 3D seismic data for study of crack detection.
