摘要
平衡剖面技术是地质思维和计算机技术的结晶,使对断层构造的研究提高到定量阶段,其依据是在垂直构造走向的剖面上,地层长度和面积(2D)或体积(3D)是均衡的。在此原理基础上利用数学手段对盆地的构造发育史进行正演和反演模拟,直观地再现地下构造的原始几何形态,迅速提供地震剖面的构造解释方案,并对解释结果进行检验(不平衡的剖面其解释一般有问题),为深刻认识构造发育史、分析油气运移及聚集规律提供依据,提高了工作效率。其结果也为盆地模拟、油藏模拟、定量计算构造伸缩量等地质研究打下了坚实的基础[1]。
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.Its basis is that the length, area(2D), volume(3D) of the strata are balanced in the inline section . Based on 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 subsurface 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, this method can provide the evidence to recognize deeply the developing history of structure, to analysis oil and gas migration and accumulation and also can enhance the working effectiveness extremely. The results studied can be the foundation of geological research for modeling, of basin and reservoir characteristic , the calculation of structure magnitude enlarged and diminished.
