摘要
裂缝及断裂的分布影响着潜山的储层和成藏条件,以华北潜山1区地震数据体为研究对象,对构造平滑后的数据体分别进行常规曲率计算,曲率坐标旋转和蚂蚁体属性的计算来预测裂缝和断裂的大概分布情况,多种属性对比后发现这些单一属性虽然都能不同程度反映裂缝发育,但都有各自的弊端。为了提高裂缝预测效果,弥补单一属性的缺陷,在优化后的曲率属性的基础上进行追踪步长缩小后的蚂蚁体计算,形成新的融合属性体,新方法提取的蚂蚁体属性反映出裂缝连续性更好,分布规律更加清晰,东南部大断裂较为突出,与地质资料对比后结果可靠,为后期工作提供借鉴。
The distribution of fractures and faults affects the reservoir and accumulation of buried hills.Taking the seismic data volume of east China buried hill area 1 as the research object,the curvature,coherence,and ant body attributes of the data volume after structural smoothing are calculated respectively to predict the general distribution of fractures and faults.After comparing multiple attributes,it is found that although these single attributes can reflect fracture development in different degrees,they all have their characteristics.The disadvantages of self-reliance.In order to improve the effect of fracture prediction and make up for the defect of a single attribute,the ant body calculation after the tracking step is reduced based on the curvature attribute to form a new fusion attribute body.The optimized ant body attribute reflects that the fracture continuity is better,the distribution law is more precise,the southeast significant fault is more prominent,and the result is reliable compared with the geological data,which provides a reference for the later work theoretical basis.
