摘　　要：越来越多的地震方法被引入用来解决地质问题,却忽略了传统地震相分析这一与地质因素联系最为直接的方法。通过川东南地区下古生界地震相研究,在该地区识别了前积地震相、丘状地震相、透镜状、梭状、波状及弱变振幅、眉状等典型地震体,平面上进行地震相组合之后,结合区域地质资料及单井沉积相分析,可以指导沉积相精细研究,预测有利储集体分布区带,指导储集层预测研究,该方法对于那些勘探程度不高的地区意义尤为重要。Through the seismic method to resolve the geology problem, more and more new way is advanced, however, the traditional seismic facies analysis technique, which has directness contact with the geology factors, is neglected. Based on the seismic facies analysis in the southeast margin of Sichuan basin, the prograding structure seisic facies, slump andenticular seisic facies, wave seismic facies and va-ried ampli- tudes seismic facies are identified. Using the seismic facies assemblage analysis method, combined with geological data and the sedimentary facies anasylis of single drill, to study the sedimentary facies and reservoir prediction research, is very easy, and is quite adapt to carry out in the relatively lowdegree ex- ploration areas of lacking drill bores.
