| Abstract: | Based on 22 mercury injection samples and 4 440 effective physical properties analysis samples,established is a classification standard of low porosity and permeability reservoirs.This is the classification standard based on log data.According to this classification standard,the 253 reservoirs are classified,the log characteristic parameters of reservoirs classification are selected, the range and the average value of the parameters on 3 types of reservoirs are established.Meanwhile self-adapted neural networks technology is used to establish reservoir classification model in Chang 63 block,and its results are close to the comprehensive analysis results.Through analyzing the relation between the reservoirs index and productivity of hydrocarbon reservoirs,there is a well correlation between the reservoirs index and the productivity.This model of productivity prediction based on reservoirs classification has been successfully applied to Chang 63 block, Baibao area. |
