断层相关褶皱解释之平衡剖面技术

从实际问题出发,扼要阐述了平衡剖面技术的基本概念,并结合实例着重探讨了其应用研究.在介绍了与平衡剖面有关的基本概念的基础上,总结平衡剖面技术的研究流程和平衡剖面结果的评价标准,结合缅甸区块实际资料深入探讨其在断层相关褶皱构造模式建立和检验调整地震解释以及在恢复挤压构造发育史方面的应用情况,显示了其在缅甸区块叠瓦状断层转折褶皱的良好应用效果,并获得剖面的水平延展量,同时也认识到许多潜在的客观问题,有待进一步探索.

Balanced Section Technology for Interpretation of Fault-Related Folds

In this paper, the basic concept of balanced section is discussed, with focus on its application in solving the practical problems. Firstly, kinematic method, especially fault parallel flow method, is commonly used for interpretation of compressional structures. Secondly, the workflow and criteria of balanced section are summarized. Finally, with the practical application data of balanced section technology in the block of Myanmar, the application results of balanced section technology in building the fault related fold structural model, the model modification, seismic data interpretation, the structural evolution restoration of compression structures. The application results show that good effects of balanced section technology have been obtained on interpretation of imbricate fault- bend folds. In addition, the horizontal extension has been calculated based on the above research. At the same time, we further realize that there are many potential objective problems to be studied continually in the future.
