摘要
在对白水头地区低阻油层的地质特征、物性特征及成因环境进行了分析研究后 ,应用测井曲线特征集法 ,把白水头油田常规油气层、低阻油气层、油水同层、水层等看成是独立的地质事件 ,建立了它们与测井曲线特征之间的对应关系 ,利用这种关系对未知地质事件进行了预测划分。最后根据所建模型定量计算储层各种参数 ,收到了良好的地质效果 。
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 computatioal 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 featrue aggregating method.A good geologic result shows this method is effective in identifying multi genetic oil/gas zone with low resistivity.
