Abstract：Aimed at the problems existed in reservoir prediction during oilfield development,the paper summed up a set of ideas suitable for fine reservoir prediction in complex geologic conditions of China and available techniques that mainly include the following aspects:1.fine structural interpretation techniques;2.logging-data-based sedimentary mi-cro-facies model-building techniques;3.logging da-ta correction and normalization processing techniques;4.techniques of studying logging response of reservoir;5.techniques of high-precision inver-sion of reservoir;6.computation of reserve and well-site deployment etc.The total process is both independent and uniform iterative studying pro-cess.The paper presented facies-controlled-isochronal mini-strata correlation method in view of the problems existed in mini-strata correlation and logging-data-based sedimentary micro-facies model-building technique,which can improve the precision of mini-strata correlation.Finally,the method was used for the prediction of Dagang Ban-nan well-site 4-2 oilfield and good results are gained.
