摘要
针对稠油油藏蒸汽吞吐后期汽窜严重的现象,开展了蒸汽泡沫调驱的室内实验研究,绘制了吞吐后期提高采收率措施选择图版。利用数值模拟技术,对埕南91块超稠油田进行了提高采收率措施优选,优选结果与图版法得到的结果相同,证明了图版的正确性,为类似稠油油藏提高采收率方法的选择提供了借鉴。
In view of steam channeling during cyclic steam stimulation process for heavy oil reservoir, a laboratory experiment is conducted to study profile control by steam foam. The chart of the selection of EOR method is drawn according to the experiment data. The EOR technology for Chengnan 91 block is optimized by numerical simulation method. The result agrees to that from the chart, proving the correction of the chart. The study is supposed to pro- vide guidance for the selection of EOR technologies for the similar heavy oil reservoirs.
