摘　　要：现今的平衡剖面技术是地质思维和计算机技术结合的体现,是构造研究的定量化阶段,其依据是在垂直构造走向的剖面上,地层长度和体积(三维)或面积(二维)是守恒的。在此原理基础上利用计算机手段对盆地的构造进行正演和反演模拟,直观地再现研究区构造发育史,同时,在构造解释方面也提供了约束条件,减少了构造解释的多解性,并对解释结果进行检验(不平衡的剖面里一定有不合理的解释方案),对解决一些地区的基本构造问题有很大的帮助。以DHY地区的剖面为例,结合区域地质资料,用反演法对该地区的构造解释方案进行了验证,并再现了该地区的构造发育史。The technique of＂balance section ＂is a combination of geological thought and computer technique,which improves the research for fault structure up to quantitative stage.It＇s basis is that volume（3D）,area（2D）of the strata are balanced.Based on the above theory,the math measure is used to model the developing history of the structure in one basin both positively and negatively,then the primary geometry of the structure history can be displayed directly.This method can provide the structure interpreting plan for the seismic profiles instantly and can correct the results interpreted.Usually there are some problems concerning the interpretation.Meanwhile,it＇s helpful to resolve some basical problems of structure.Take DHY area for example,we verify the structure plan by using reversal development method,and replay it＇s structure history.
