摘要： 碳酸盐岩潜山油气藏是南堡凹陷最为重要的油气藏类型，岩溶作用对其具有控制作用。为了增强对南堡凹陷岩溶发育规律的认识，以FMI测井资料为主，结合常规测井、录井以及岩石薄片等地质资料，总结岩溶发育控制因素的FMI测井响应特征，建立了高阻裂缝相、高导裂缝相、溶蚀扩大缝相、溶蚀孔隙相和洞穴垮塌相5种FMI测井相。通过数据统计，建立了岩溶发育特征与FMI测井相的配置关系。研究结果表明，南堡凹陷发育上部表生岩溶带和下部埋藏岩溶带，表生岩溶带主要发育高导裂缝相、溶蚀孔隙相和洞穴垮塌相，其中，洞穴垮塌相是表生岩溶带特有；埋藏岩溶带主要发育高阻裂缝相、溶蚀扩大缝相、溶蚀孔隙相。岩性与断层是岩溶发育最主要的控制因素。

Abstract: Carbonate buried?hill reservoir is the most important reservoir type in the Nanpu sag with controlling effect of karstification on it. In order to further understand the pattern of karst development in Nanpu sag, based on formation microlog imaging (FMI) logging data integrated with geological data such as conventional logging data, log data and thin section analysis of rocks, this paper summarizes the characteristics of FMI logging response controlled by karst development, and establishes 5 logging facies such as high?resistance fracture facies,high?conductivity fracture facies, enlarged dissolution fracture facies, dissolved pore facies and cave collapse facies. A relationship between karst development characteristics and FMI logging facies is established on the basis of data statistics. The result shows that epigenetic karst belt is developed in the upper part of Nanpu sag and the buried karst belt in the lower part, and high?conductivity fracture facies,dissolved pore facies and cave collapsse facies are mainly found in the epigenetic karst belt, and the cave collapse facies is a unique feature for this belt; while high?resistivity fracture facies, enlarged dissolution fracture facies and dissolved pore facies are mainly found in the burial karst belt. Lithology and fault are the dominant controlling factors for karst development
