摘要: 详细介绍了岩溶和古岩溶的概念,按岩溶发生时间、深度、岩石介质、发生环境和成因机制对岩溶进行分类;根据岩溶水动力学特征,岩溶纵向上大致分为风化壳、垂直渗流带、季节变动带、水平潜流带和深部缓流带。综合前人的研究成果,论述了油气储层古岩溶发育相关的10个地质因素,列举了7种岩溶发育机理,并总结分析了岩溶研究的进展及其发展趋势。

Abstract: According to karstification time, depth, rocks medium, producing environment and mechanisms, karst can be classified into karst and paleokarst, and in vertical it also be divided into five belts including weathered layer, vertical seepage belt, seasonal changed belt, horizontal seepage belt and deep sluggish belt based on the features of karst's hydrodynamics. After summing up the former researchers' results, it is discussed that 10 geological factors are related to develop the paleokarst of oil-gas reservoirs and 7 kinds of karst developing mechanism, and is concluded the progress and the development tendency of karst research in the future
