摘要
在前人的基础上分析湖泊相带的划分,提出了湖泊相新的划分方案,把湖泊划为深水湖-较深水湖亚相、浅湖亚相、滨湖亚相,在湖泊环境中发育湖底扇亚相、湖控亚相(三角洲前缘亚相、前三角洲亚相、扇三角洲扇前缘亚相、水下河道、水下河口坝)都划为湖泊相,更有利于研究湖泊相的沉积体系。结合自然电位和视电阻率曲线上的可识别特征,使湖泊相带的研究向定量化发展。
on the basis of available work results a new scheme of division of lake facies is put forward, i.e., the lake is divided into deepwater-relatively deep-water lake subfacies, shallow-water lake subfacies and lakeshore subfacies, and lakebed fan subfacies, lake-controlled subfacies （delta front subfacies, prodelta subfacies, fan delta fan-front subfacies, underwater channel, underwater channel-mouth bar） developed in the environment of lake facies are all classified into lake facies. This is more conducive to studying its sedimentary system. In combination with natural potential and identifiable features of the apparent resistivity curve, the research of lake facies tends to be quantitative.
