【摘要】 在系统介绍岩芯裂缝基本参数统计的基础上，给出岩芯裂缝空间分布规律的表示方法，并概括了裂缝孔隙度和渗透率的估算方法，提出有效孔隙度、渗透率和单井控制的有效裂缝体积可作为裂缝性储集层等级划分和裂缝综合评价的依据。更多还原

【Abstract】 On the basics of introduction ahaut pararneter statistics of drilling core fractures systematically, the paper give us how to express spatial distribution of core fractures, as well estimate Porosity and permeability of fractures. In addition, we advance that effective porosity,Permeability and effective volume of fractures controled by signal well could take as foundation ahat differentiating classes of fractured reservoirs and evaluating fractures.更多还原
