摘　　要：平衡剖面技术的原理是建立在与构造走向垂直的剖面上,地层长度、面积(2D)、或体积(3D)具有均衡性的基础上,并使用数学方法对构造发育史进行正演和反演模拟,以再现地质构造原始几何形态,揭示构造发育过程及对地震解释结果进行验证等。通过介绍平衡剖面技术制作过程中应遵循的原则、制作步骤,对河南某区的构造演化过程进行了分析,认为该区的加里东期运动为海西期煤系的沉积提供了稳定的条件;而后来的印支期、燕山期以及喜山期等多期运动的叠合,导致区内构造发育,并在早期形成的断层面或二1煤层之上的软弱层段建造了广泛的滑动构造格局。The principle of balanced cross section technology is based on the section perpendicular to the structure strike, while the length, area （2D） or volume （3D） of stratum has proportionality. Using mathematical approach carried out forward and inversion model-ing for structural development history to reproduce the original geometry of geological structure and reveal structural development pro-cess as well as verify seismic interpreted results etc. Through introduction to principles should be followed during the balanced cross section making procedure, analyzed structural evolution process in a Henan region, and considered that the Caledonian orogeny had provided stable condition for the Hercynian coal measures deposition. Superimposed later Indosinian, Yanshanian and Himalayan movements have resulted in developed structures in the area and made the weak strata upon previous fault plane or coal II 1 formed ex-tensive gliding tectonics pattern.
