摘要: 断裂（裂缝）对油气藏既有破坏又有保存作用。胜利埕岛奥陶系潜山油藏受裂缝控制，非均质性强，勘探目标预测难度大。本文以地震边缘检测为先验信息和启发因子，在自适应地震相干数据体上进行蚂蚁体追踪，精细检测裂缝，弥补了单一相干体检测分辨低的缺陷，获得了与钻井和实际地下情况吻合度更高的裂缝检测结果。对该区的油气勘探起到了指导作用。

Abstract: Fractures can destroy and preserve oil and gas reservoirs. The buried hill reservoir of Shengli Chengdao Ordovician is controlled by fractures and has strong heterogeneity. In this paper, with seismic edge detection as prior information and heuristic factor, ant body tracking is carried out on adaptive seismic coherence data body to fine detect cracks, which makes up for the defect of low resolution of single coherence body detection, and obtains the fracture detection results with higher coincidence degree with drilling and actual underground conditions. It plays a guiding role in oil and gas exploration in this area.
