摘要
提出了利用FMI成像测井信息定量计算溶洞裂缝性碳酸盐岩储层面元大小、溶洞分布百分比、裂缝平均宽度、平均长度和裂缝发育密度等参数的方法。该方法包括利用Roberts算子进行溶洞边缘检测,用基于方向曲线的方法进行边缘跟踪和细化,从而实现溶洞的自动提取和定量计算。该方法通过提取特征点、跟踪得到特征点方向序列、并利用其对应的方向曲线进行溶洞判别。其算法计算量较少,判决速度快。
The reservoirs of crack carbonate are also very meaningful to oil and gas exploration A new method utilizing FMI logging information is proposed for analyzing quantitatively the size of solution cavity areas, distribution solution cavity, average width and length of cracks as well as the density of crack growthThe new method involves detecting the circumference of solution cavity and automatically pickuping setpoints, tracking directional sequence resulting in the setpoints and accurately determining solution cavity The calculation work needed is much lesser and making determination is rather quicker
