【摘要】 裂缝构造建模主要针对大尺度裂缝,通常采用Petrel建模软件中的蚂蚁追踪属性进行三维地震的大尺度裂缝自动追踪和解释。该方法能克服人工地震解释工作中主观性大,难以在各个平台间进行数据交换的缺点,以及解决构造和岩溶作用过程中形成的断裂方向性差,难以进行表征的难题,大大提高了解释精度,缩短了人工解释时间。但是该方法在蚂蚁追踪属性体提取过程中对参数意义及其对结果的影响了解甚少。因此,通过运用对比试验对蚂蚁追踪属性体提取过程中的6个参数的影响作用进行了仔细研究,并建立了塔河四区奥陶系大尺度裂缝模型,总结并验证了利用蚂蚁追踪属性提取的大尺度裂缝标准,可为以后的构造建模提供参考依据。更多还原

【Abstract】 Fracture structural modeling was mainly for large-scale fracture modeling.Usually ant tracking attribute in Petrel reservoir modeling software was used to track and interpret large-scale of fractures in 3D seismic automatic.It overcomes the shortcomings of high subjectivity factors in seismic interpretation and difficulty of data exchange between different platforms;various problems were solved in fracture characterization and poor fracture orientation resulted from the tectonic movements and the process of karst;interpretation accuracy was greatly improved,manual interpretation time was reduced.But the parameters in the extraction course using the method were less known.The influence of 6 parameters in the extraction course of ant tracking could be carefully studied by comparison.The model is established for Ordovician large-scale fracture in Region 4 of Tahe Oilfield,the standards of the large-scale fractures are summarized and validated by using ant tracking technology.Finally it provides reference for future fracture structural modeling.更多还原
