本文以断裂精细解释技术和地震属性分析技术为基础,通过对断裂具有响应特征的地震属性进行优化组合,有效刻画了研究区大级别断裂和微断裂的平面组合以及交切关系。工作流程首先以基于导向的相干体属性控制断裂展布趋势,然后优选融合凸显局部细节的倾角体、方位角体和曲率体等地震属性体精细刻画三、四级断裂和微断裂的空间展布特征,通过该方法有效识别出研究区断裂的5种平面组合样式(梳状、反梳状、岔Ⅰ型、岔Ⅱ型、帚状),7种剖面组合关系(反Y字、Y字、复Y字、X型、帚状、阶梯状和叉状)。该技术方法对复杂断裂的识别具有一定的借鉴意义。
Based on the technique of fine interpretation of fractures and the analysis of seismic attributes, this paper combines the seismic attributes of faults with the optimal combination to effectively characterize the plane assemblages and the relations of the intersections of large-scale faults and micro-faults in the study area. The work flow first controls the trend of fracture distribution based on the properties of oriented coherence bodies. Then, it is preferable to finely describe the spatial distribution of the third- and fourth-order faults and micro-faults by integrating seismic attribute bodies such as dip bodies, azimuth bodies and curvature bodies that highlight local details By using this method, five kinds of plane combination patterns (comb, anti-comb, bifurcation Ⅰ, bifurcation Ⅱ, and broom-shaped) Complex Y word, X-type, broom-like, stepped and fork). The technical method has certain reference value for the identification of complex faults.
