平衡剖面技术应用的条件及实例分析

平衡剖面技术是一种遵循几何守衡原则而建立的地质剖面正、反演方法，它是构造变形恢复的重要手段。近年来，随着大型计算机及相应软件的出现，使得该技术能够在许多地区得到普遍应用。

Application condition of balanced-section technique and the case analysis

Balanced-section technique is a forward-inversion method of geologic section,which is based on geometric conservation principle. It is an important means for therecovery of structural deformation. In recent years, huge computer with sophisti-cated softwares makes the technique widely used in many prospects. As a matter offact, each balanced-section technique has its own application conditions. Applica-tion conditions of Geosec 4. 1 software are discussed in detail. The balance compu-tation of five seismic sections in the Kuche depression of Tarim basin has been madeto offer a reasonable result. The result says that major structural shortening is30%~40% and happened in mid-late Cenozoic. Then the original seismic interpre-tation has been revised desirably.
