摘要(Abstract)：
喇南试验一区完成葡Ⅰ 1— 2油层聚驱试验后 ,开始上返萨三组油层。针对上返层系的油层特点 ,提出了两种层系组合的原则。根据实际情况 ,推荐以二类油层为主并适当扩大部分三类油层的上返方式进行层系组合 ,最终确定萨Ⅲ 4— 10油层作为开展聚驱上返试验的目的层。在分析和研究萨Ⅲ4— 10油层地质特点及动用状况的基础上 ,提出了 6种聚驱井网的调整方案。通过分析对比 ,推荐采用将现注聚井网注采井别互换后的 2 12m五点法面积井网方案 ,为该区块聚驱上返试验取得良好效果奠定了可靠基础。
This paper carries on a research thoroughly to the question of layer system's geology characteristic upon PI1-2 oil layer and the layer system composition, through the analysis compare and contrast many kinds scheme of pattern arrangement, it extracts best scheme from schemes about better thick oil reservoir polymer flooding upon PI1-2, and establishes the reliable foundation to polymer flooding.
