平面模型铬交联聚合物调剖物理模拟

The physical mod-elling of profile control by Cr(Ⅱ)-polyacrylimade gel i`n tbe planar geological model.

按纵向非均质、正韵律、渗透率变异系数为０．７２的地质条件设计制作了平面非均质物理模型，以３３３０Ｓ型部分水解聚丙烯酰胺与三价铬形成的凝胶为调剖剂，用五点法井网布井，调剖深度为１／３井距，开展交联聚合物调剖实验，分析调剖剂的纵向调整及平面控制效果，为现场应用提供了较详实可靠的实验依据。

heterogeneous planar physical model with positive rhythm and permeability variation of0. 72 is designed and manufactured according to the geological conditions. The experiment ofprofile control by crosslinked polymer of Cr(Ⅱ)-polyacrylimade gel is made in a five spotpattern. The depth of profile control is 113 of the well spacing. The effectiveness of the verti-cal modification and planar control is analyzed,providing reliable experiment basis for fieldapplication.
