Abstract：In this paper the lacustrine carbonate at Es4 in Zhanche Area is the study object,based on the analysis of sedimentary environment,three subfacies classification schedule was presented in this paper,the three subfacies are the reef,the granular beach and the lime-mud.Based on development areas,the reef subfacies can be divided into the basin-marginal fault terrace,the height of slope,and the high productivity slope break.Based on the subfacies studies above,the quantitative relationship between different subfacies and key seismic parameters was determined through the quantitative identification for the model characteristics of the lacustrine carbonate,and the subfacies development areas of the lacustrine carbonate were predicted through high precision paleogeomorphology recovery technique and waveform classification technique,while the prediction of the favorable reservoir and fracture development areas were conducted through frequency division attribute technique and fracture prediction technique.The drilling for the targets proved the effectiveness of the studies.
