平衡剖面技术与地震资料解释

Balanced section technique and seismic data interpretation

地质剖面形成至今，一般都经历了数千百万年乃至数亿年的构造形变过程。但其面积（体积）、地层厚度、各标志层的长度在变形前后保持相等，即变形前后的剖面是平衡的。根据这些原则制作的平衡剖面可以作为检验地质构造解释是否正确合理的标准。本文简要介绍了平衡剖面技术及其发展，并论述了平衡剖面技术的正演法和复原法及其在地质解释中的应用。

Generally speaking,geological section has undergone structural deformation for several million years to several hundred million years. But the area, bed thickness and marker bed length remain unchanged ;that is to say,the geological section keeps balanced before and after deformation. The balanced section plotted according to the principle can serve as the standard by which we can verify whether the interpretation of geological structure is reasonable. We sketch out balanced section technique and its development. We also describe the forward and backward methods of balanced section technique,and their applications in geological interpretation.
