摘要(Abstract)：

随着国内主要油田逐渐进入特高含水开发期,层间矛盾日趋严重,现有调剖技术从经济和技术两个方面都难以满足矿场调剖实际需求,亟待开发高效、低成本调剖技术。为此,通过研究粉煤灰及其改性产物———人工沸石的外观结构和表面性质,提出将人工沸石用于治理特高渗透层的设想。物理模拟实验结果表明,在化学剂费用相近和段塞尺寸相同条件下,人工沸石携带液+聚合物溶液调驱可以比聚合物驱提高采收率2%以上,是一种极具发展潜力和应用前景的调剖技术。

Current profile modification technique cannot meet the demand of the actual profile modification in technical and economic view. New profile modification technique with low cost and high efficiency needs to be studied. This paper proposes an assumption of using artificial zeolite to treat ultra-high permeable zones through studying its structure and property. Physical simulation experiment shows that, with similar cost of chemical and same size of slug, artificial zeolite carrying fluid+polymer solution can increase recovery 2% more than polymer flooding. It is a potential technique.
