| 摘 要： | 平衡剖面技术广泛应用于构造解释合理性检验和构造演化史分析。平衡剖面发展历史与现状表明,二维平衡剖面技术理论与应用已趋于成熟,真三维平衡恢复算法的精确实现和实际应用是今后的主要发展方向。在详细总结二维平衡剖面技术原理和制作过程后,以苏北盆地溱潼凹陷为例,紧密结合区域地质与地球物理资料、选择合理的剖面走向、采用变速时深转换,多次修改地震构造解释方案并最终制作平衡剖面。结果表明,合理运用平衡剖面技术可检验地震构造解释的合理性并分析构造演化历史,指导油气资源勘探。

| Abstract: | Balanced cross-section technique is widely applied to structural interpretation and restoration. A review of the development of the technique is made in this paper. It shows that the technique for 2-D balanced cross-section is now nearly mature and the 3-D balanced cross-section restoration remains to be studied. In this paper, we selected two key seismic profiles from the Qingtong Depression of the North Jiangsu Basin for 2-D balanced cross-section restoration. After varying velocity and timedepth conversion and revision for several times, the present geological section comes into being. The results suggest that appropriate application of balanced cross-section technique can improve the seismic interpretation for structural evolution and help in resource exploration. |
