摘要： 疏水缔 合水溶性聚合物(HAWP)是大分子链中含有少量疏水基团的水溶性聚合物,在模拟某一油藏条件下,研究了HAWP和ASG两种不同类型聚合物溶液在多孔介质中的渗流特性。研究结果表明,由于HAWP分子疏水基团发生分子间缔合作用,形成动态物理交联网络,HAWP溶液表现出很强的流度控制能力;在远离注入端的多孔介质中,HAWP溶液比ASG溶液具有更高的抗冲刷性和降低孔隙介质渗透率的能力。两种聚合物溶液在多孔介质中表现出的不同渗流特性与聚合物的分子结构有密切关系。

Abstract: Hydrophobic associating water-soluble polymer (HAWP) is a kind of polymer, whose hydrophilic macromolecular chains have a few hydrophobic groups. The performances of solutions of HA W P and partally hydrolyzed polyacrylamide (PHPA) flowing through porous media are studied under the conditions of a reservoir simulation. The results indicate that HAWP hydrophobic group tends to bringing about intermolecu-lar association and dy namic and physical cross-linked network, its solution shows a great capability of mobility control, decreasing porous media permeability and anti-scour in distant porous media compared with PHPA. The different flow ing performances of these two solutions in porous media are more related to the molecular structures of polymers.

Key words: hydrophobic associating water-soluble polymer, porous media, percolation, rheological characteristics
