近十几年来,由于石油勘探中数字地震勘探技术的提高,尤其是三维地震的开展,对大中型断裂的深部结构有了更为清晰的揭示,出现了许多花状构造(flower structures)。对于花状构造的研究已有报道,本文不作全面论述,着重结合与地震地质相关的问题进行简要探讨,为了便于读者对花状构造有必要的了解,首先作些特征介绍。一、花状构造的一般特征花状构造的特征是:平面上是由一条贯穿的主干断裂与其旁侧同期的雁列压性或张
In recent decades, due to the improvement of digital seismic exploration technology in petroleum exploration, especially the development of 3D seismic, the deep structure of medium and large faults has been revealed more clearly, and many flower structures have appeared. The research on the flower-shaped structure has been reported. This article does not give a comprehensive discussion. It focuses on the issues related to the seismic geology. In order to facilitate readers’ understanding of the flower-shaped structure, some characteristics are introduced first. First, the general characteristics of the flower-shaped structure Flower-shaped structure is characterized by: the plane is by a main break along with its side of the wild goose column pressure or Zhang
