摘要:
从储层大孔道发育程度和高含水期水驱效果两方面对Z35断块戴二段高含水期开发特征进行评价,认为该层系目前水驱速度快,存水率低,说明油藏中形成优势渗流通道后,大量注入水沿着这些通道无效循环,开发效果变差。应用模糊综合评判法对该单元的注采有效性开展研究,选取对注采关系影响较大的静态和动态指标,应用模糊层次分析对各项指标的权重进行分配,经过模糊综合计算得到正常生产、低效循环和无效循环三种生产状态的综合评分区间,经过模糊运算认为Z35断块戴二段现阶段处于注水低效循环阶段。
Abstract:
Z35 fault-block E2d2 development features at high water cut stage including maturity of breakthrough flow channel and effectiveness of water flood have been analyzed .It is recognized that the water displacement velocity of this block is fast and the net injection percent is low. Due to the above-mentioned point of view, after formation of breakthrough channels, most injection water moves in circles through the breakthrough channels, then, the waterflood effectiveness becomes worse. After that, the effectiveness of waterflood is evaluated by using of fuzzy comprehensive evaluation.The static index and performance index related to water flood effectiveness are selected.The weight of index is firmed by using of FAHP.Three intervals are divided:regular production, inefficiencies circles, and non-effective circles. Z35 block is believed in inefficiencies circles by using this algorithm.
