摘　　要：在对岩心扫描的基础上 ,利用图像分析的方法 ,对火成岩和灰岩发育孔、洞进行目标自动提取 ,相关参数自动计算 ,结合实例进行了分析对比。该方法解决了以往单纯依靠人工统计存在的误差大及费工费时的问题。岩心面孔率参数的分析计算 ,弥补了实验室对火成岩、灰岩等特殊岩性非均质储层孔隙度参数计算的不足。Pores and cavities developed in igneous rocks and limestones are extracted automatically as target and related parameters are calculated automatically, and correlation is done with cases based on core scanning by using the method of image analysis. The problems of big error, labourconsume and timeconsume by artificial statistic before are solved by this method. Analysis and calculation of parameters of core plane porosity make up the calculation inadequacy of porosity parameter in heterogeneous reservoirs with special lithology of igneous rocks and limestones.
