摘　　要：成像测井对于评价碳酸盐岩储层地质特征有很好的效果,但成本较高。在分析成像提取的缝、洞发育参数与常规测井各响应之间相互关系的基础上,研究了常规测井响应与缝、洞发育的相关程度。应用多元线性回归方法,建立以常规测井响应计算缝洞发育参数裂缝密度、裂缝视孔隙度、溶孔密度和面孔率方程。对回归效果进行对比分析与地层的实际情况符合较好。Imaging logs have good effect in evaluating the geological characteristics of subsurface carbonate reservoirs, but their cost is high. The authors have investigated the correlativity between conventional logs and intensity of fractures and/or vugs, and set up relationships between them using multi-variants linear regression. Then the fracture density, fracture porosity, vug density and vug area can be calculated from conventional logs. The application results indicate that the effect is preferable because calculated parameters over the fractured and/or vuged section appear to be high.
