Study on micro-facies analysis technique for Hua 64 block in Nanliang Oilfield

The division plan of sedimentary facies was determined by using plentiful identifying symbols of sedimentary facies and the practical data in Hua 64 block of Nanliang Oilfield.The reasonable technique for sedimentary micro-facies analysis was proposed on the basis of micro-facies research content and requirement.The wavelet analysis technique,grey system technique,cross plot and log facies analysis technique were used to research the micro-facies pattern.The research results can provide the base for making regula tion plan of oilfield exploitation.
