For this purpos , from the point of the log geology , aimed at the actuality of the current fractured reservoir log geology interpretation and evaluation , based on synthetical analysis of the current domestic and foreign fruit of fractal dimension investigation of reservoir fracture , using the method and technique of fractal dimension , through the further discussion of the fractal dimension characteristics of m index and n index in the log interpretation archie model in a sample way and through the theoretic reasoning to the fractal dimension dfa and m index of fractured reservoir interval ' s log curve , according to the geophysical signification of the fractal dimension dfa of fractured reservoir interval ' s log curve shape : the more complicated the change of the curve shape is , the larger the its dfa value is , then the more complicated space structure of fracture and pore , then the higher value of m index of space structure of fracture and pore , and so on , the text propounds an improved method , based on box dimension , of covering log curve with scale grid , and by programming computes the dfa and its m index value of fractured reservoir interval ' s log curve , for instance , ac and rt curve , ect , then further puts this technique into application investigation , and makes analysis of application effects in the reservoirs located in l area of qx oil field from three aspects : 1 . the dfa and its m index value of fractured reservoir interval ' s log curve , for instance , ac and rt curve , ect , which are derived from computing , is used to identify reservoir type by crossplotting m index with the product df _ acrt of fractal dimension of acoustical wave log curve and restivity log curve and by experiential discriminance plate of reservoir type in l area of qx oil field 因此，对该区裂缝性储集层的类型识别、孔渗特征的测井地质解释以及储层裂缝的发育和分布规律进行深入的研究便成为本文研究的出发点。为此，本文从测井地质的角度，针对当前裂缝性储层测井地质解释与评价的现状，在综合分析当前国内外储层裂缝的分形分维研究成果的基础上，利用分形分维方法和技术，通过对archie测井解释模型中的m指数、 n指数的分形分维特性的深入浅出的论述以及裂缝性储层段测井曲线分维d _ ( fa )与m指数的理论推导，根据裂缝性储层测井曲线形态分维值的地球物理意义? ?曲线变化越复杂，则其分维值d _ ( fa )越大、裂缝孔隙空间结构越复杂、裂缝孔隙空间结构指数m值越高等特征，提出了改进的基于盒维数的测井曲线网格覆盖法，编程计算了裂缝性储层段常规测井曲线(如声波和电阻率曲线)上分形分维值及其m指数值，进而从以下三个方面对qx油田l区块的裂缝油藏进行应用研究，效果十分理想： 1将计算得到的可变的m指数与声波和电阻率分维之积df _ acrt进行交绘，采用储层分维值分类技术统计分析这些参数变化的规律，并结合qx油田l区块储层类型经验判别图版，从而实现qx油田l区块下白垩统的裂缝性储层的类型识别。
