摘要: 疏水缔合聚合物具有优良的增黏性和抗盐性, 但其“ 网状” 分子聚集体与储集层孔喉间适应性成为石油科技人员关注的问题。针对矿场实际需求, 以油藏工程、 物理化学和高分子材料学等为理论指导, 以化学分析、 仪器检测和物理模拟等为技术手段, 以大庆南三区储集层地质和流体为研究对象, 开展了改善疏水缔合聚合物储集层适应性方法和效果实验研究。结果表明, 随β - 环糊精质量分数增加, 疏水缔合聚合物溶液黏度呈现先快速降低后趋于平稳趋势。当β - 环糊精质量分数为0. 0 7%时, 疏水基团间缔合作用受到完全抑制, 此时的黏度值为聚合物溶液本体黏度。β - 环糊精可以减小疏水缔合聚合物分子聚集体尺寸, 扩大聚合物分子线团储集层波及范围, 进而改善疏水缔合聚合物油藏适应性。

Abstract: Hydrophobic associating watersolute polymer has excellent viscosity and salt resistance, but the adaptability between its "mesh" molecular aggregation and reservoir pore throat causes attention of petroleum technology staffs. Aimed at the actual need, guiding by reservoir engineering, physical chemistry and organic chemistry, the adaptability with hydrophobic associating polymer and experimental effect on southern reservoir were carried out using instrumental analysis, chemical analysis and physical simulation as technical means. Results showed that with the increasing of β-CD, the viscosity of hydrophobic associating water solute polymer solution first reduced quickly and then got stable. When the concentration of β-CD was 0.07%, hydrophobic association between groups was completely suppressed, and the viscosity of polymer solution was bulk viscosity. In addition, the aggregation size of hydrophobic associating polymer molecular was decreased by β-CD, and the entering extent to reservoir of the polymer molecular group was expanded, thus the adaptability of hydrophobic associating water solute polymer with reservoir was improved.
