摘　　要：应用沈平平、李克文等人提出的计算砂岩孔隙结构分形维数的ＭＩＦＡ法，对克拉玛依油田三叠系克下组砾岩储层的孔隙结构分形维数进行了研究。认为克拉玛依砾岩储层的孔隙结构具有分形特征，孔隙结构的分形维数可定量描述孔隙结构的复杂程度，分形维数愈接近２，孔隙表面愈光滑，储层储集性能愈好，反之，储集性能愈差。The study on fractal dimension of pore structure in Lower Karamay formation conglomerate reservoir of Triassic in Karamay oilfield has been made by means of MIFA method for calculating fractal dimension of sandstone pore structure presented by Mr. Shen Pingping and Mr.Li Kewen, it is concluded that pore structure in Karamay conglomerate reservoir has fractal characteristics, the complexity of pore structure can be quantified by fractal dimention of pore structure, and fractal dimension is closer to 2, pore surface is smoother, reservoir quality is better,Otherwise, reservoir quality becomes worse.
