| 摘 要： | 三维地震技术对沉积学的发展有着重要的推动作用，主要体现在分析方法和概念上.高精度的三维地震数据可以通过对沉积要素的直接成像来重建三维的沉积古环境，也可以通过对不同地质历史时期的古沉积环境进行成像来研究沉积演化史.地震数据联合测井数据也可以通过预测岩石性质分布来定量描述沉积岩的非均质性.在成岩作用分析工作中，高分辨率的地震成像用优于10 m的纵向分辨率在上千平方千米的范围内描述成岩界面的几何形态，是一种在整个盆地范围内研究成岩作用过程的新方法.应用三维地震技术解决沉积问题这一领域未来发展潜力巨大.对相关的方法、工作流程和研究实例进行了论述.

| Abstract: | The progress of 3D seismic technologies plays an important role in the development of sedimentology in terms of analytical methodology and concepts.High-density and high-resolution 3D seismic data can be used to reconstruct 3D views of sedimentary paleo-evironment by direct imaging of depositional elements,and can also be used to analyze sedimentary paleo-evironment evolution in 3D detail by mapping facies variability at a specific geologic time.Such data,together with well logging data,can be applied for predictions of rock distribution by properties to quantitatively delineate the sedimentologic heterogeneity.The high resolution of 3D seismic data mapping can also be adopted to image the geometry of diagenesis front to a resolution of a few meters over thousands of square kilometers,which is a new approach to the study of diagenesis process in basin scale.The potential for future development in this field is considerable.Relative methods,workflow and examples of such studies on the aspects mentioned above are presented in this paper. |
