摘要: 孔隙型碳酸盐岩储层非均质性强，孔隙结构复杂，利用通常的测井解释方法求取的物性参数与岩心实验数据差别明显。通过储层沉积微相分析，相同沉积微相的储层通常具有相似的岩性特征、物性特征和孔隙结构特征，测井响应特征也类似。在沉积微相分析的基础上，依据其测井响应特征，利用测井参数交会图法求取物性参数；使用孔隙结构参数分类评价方法，建立基于沉积微相约束的测井评价方法。测井解释结果与岩心分析数据吻合度高，表明这种方法应用效果显著。
Abstract: Vuggy carbonate reservoir is characterized by intense heterogeneity, complicated pore texture. The physical parameters obtained by common logging interpretation method are obviously dif-ferent from the data of core test. Through reservoir sedimentary microfacies analysis, reservoirs with the same sedimentary microfacies usually have similar lithologic characteristics, physical property and pore texture, as well as similar logging response. Based on the analysis of sedimentary microfacies and logging response characteristics, the physical parameters were calculated using the logging parameters crossplot method. The evaluation method of pore texture parameter classification was used to establish the logging evaluation method based on the sedimentary microfacies constrained. The logging interpretation results are in good conformity with the data of core analysis. It shows that the application of this method is significant.
