Log evaluation of low resistivity reservoir in Baishuitou area

Based on the study of geologic and physical characteristics of the low resistivity reservoir in Baishuitou oilfield, a new method for aggregating log curve features is used to characterize any specific geologic event such as lithology and oil-gas zone, etc.. From this point of view, the conventional oil/gas zone, low resistivity zone, oil-water zone and water zone in Baishuitou oilfield are considered as only one geologic event. And hence, the corresponding relation between log curve feature aggregate or set and the event is set up through statistics and computational mathematics. Then, the unknown geologic event is predicted and zoned by means of this relation. Finally, various reservoir parameters are also calculated quantitatively with the above log curve feature aggregating method. A good geologic result shows this method is effective in identifying multi-genetic oil/gas zone with low resistivity.
