摘　　要：针对现今裂缝建模方法存在的问题,探讨结合成像测井、常规测井和地震资料建立精细裂缝模型的思路和方法。首先,在构造平滑处理、方差体计算的基础上,利用蚂蚁追踪技术追踪获得能精确反映裂缝发育规律的蚂蚁属性体;其次,通过解释成像测井和常规测井资料,获得裂缝倾向、倾角、方位等参数信息,以这些信息为基础结合蚂蚁属性体,构建裂缝密度模型;最后采用随机建模的方法,构建M地区离散裂缝网络模型,对该模型做粗化处理,得到裂缝属性模型。该模型清晰地反映了储层裂缝的三维空间分布特征及裂缝属性特征。In consideration of the current problems of fracture modeling method,the ideas and method of fine fracture modeling were discussed in combination with imaging logging,conventional logging and the seismic data.First,ant tracking technology was used to obtain an ant tracking attribute which could reflect the development law of cracks.Secondly,based on the imaging logging and conventional logging data the fracture properties including dips,azimuths and other parameters were obtained,and based on the data and the ant attribute,a fracture density model was established.Eventually a stochastic modeling method was used to build the discrete fracture network model in M Area,and the model was roughened and its attribute model was obtained.The model clearly reflects the characteristics of fractures in three-dimensional distribution and the characteristics of fractures permeability and porosity.
