【摘要】 针对塔里木盆地碳酸盐岩裂缝空间分布特征和展布规律十分复杂的特点,综合地质、钻井、测井、地震等多方面资料,在对研究区岩心观察描述、FMI成像测井资料分析、纵波方位各向异性裂缝检测以及断层分析的基础上,运用地质统计学原理,分别应用插值算法和分形模拟等方法建立2种不同尺度和规模的裂缝空间展布模型.并将建立的裂缝几何模型转化为流体动力学模型,进而建立准确的裂缝等效渗透率模型,实现了对研究区裂缝系统的精细刻画和定量表征,取得了良好的地质效果.更多还原

【Abstract】 Because of the complicated spatial distribution characteristics of the fractures in carbonate reservoirs of Tarim Basin,a lot of geological,drilling,well logging,seismic and other various data of the fractured carbonate reservoir of Lianglitage Formation in the studied area are studied by the core observation and description,the FMI data analysis,the detection of anisotropic fractures using Peave azimuth and fault analysis,and two types of fracture spatial distribution models of different scales are established by using interpolation algorithm and fractal simulation separately based on the principles of geostatistics. The established geometric fracture models are converted into fluid dynamics models,and then a more accurate equivalent permeability model of fractures is established,which achieves the fine depiction and quantitative characterization of the fracture system in the fractured carbonate reservoir. The equivalent permeability model has a good geological result.更多还原
