摘　　要：本文对湖相碳酸盐岩高频层序的类型和受控因素进行了探讨。研究表明,该区湖相碳酸盐岩四级层序有单一型和混合型两种类型,五级层序可划分为3种沉积序列,其中,以灰岩类的高频层序成藏最为有利。高频层序"三古"受控因素中,古地貌控制宏观展布,古水深控制发育厚度,古气候控制叠置样式。The types and the controlled factors of high-frequency sequence were analyzed in the paper. The results show that the fourth-order sequence can be divided into a single type and mixed type, and the fifth-order sequence can be divided into three sedimentary sequences, in which the high-frequency sequence of the limestone is the most favorable for hydrocarbon accumulation. The palaeo-geomorphology controlled the macro distribution, palaeo-water depth controlled the development thickness and palaeo-climate controlled the superimposed styles in the ＂three palaeo-＂ controlled factors of the high-frequency sequence of lacustrine facies carbonate rock.
