THE SEISMIC FACIES STUDY OF THE LOWER PALEOZOIC AND ITS GEOLOGICAL SIGNIFICANCE IN THE SOUTHEAST MARGIN OF SICHUAN BASIN

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 varied amplitudes 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 exploration areas of lacking drill bores.
