    同沉积断层研究综述

    A REVIEW OF SYNSEDIMENTARY FAULTS

    • 摘要: 同沉积断层是沉积盆地最基本的地质构造形式,控制着盆地的空间展布、几何形态、沉积韵律以及油气储层的分布。结合国内外研究进展,本文从特征和分类、次生构造、研究方法、成因和演化理论等方面对同沉积断层的研究现状进行了总结和论述,认为同沉积断层的精细探测、定量评价和高精度模拟是今后研究的重点。基于一些构造地裂缝的发育特征和同沉积断层特点,提出了同沉积地裂缝的概念,并以西安地裂缝为例,阐述了同沉积地裂缝的特征,指出从同沉积作用出发研究地裂缝的发育模式、形成机制、破裂扩展效应以及影响带宽度是今后构造地裂缝研究的方向。

       

      Abstract: ynsedimentary fault is the most basic geological tectonic type of sedimentary basin. It controls the spatial distribution,geometric shape,internal sedimentation,and oil and gas reservoir distribution of the basin. According to advances of home and abroad,we summarize and discuss the research status of synsedimentary fault from the aspects of characteristics and classification,secondary structures,research methods,genesis,and evolution theory. We believe that the fine detection,quantitative evaluation,and high-precision simulation of synsedimentary fault are the key points of future research. Based on the development characteristics of some structural ground fissures and the characteristics of synsedimentary faults,we propose the concept of synsedimentary ground fissures. Taking Xi'an ground fissures as an example,we expound the characteristics of the synsedimentary ground fissure,and point out that the research on the development mode,formation mechanism,fracture propagation effect and influence zone width of the ground fissure is the direction of the tectonic ground fissure research in the future.
