摘要为丰富和发展聚合物减阻体系，以丙烯酰胺（AM）、2-甲基-2-丙烯酰胺基丙磺酸（AMPS）、N，N-二甲基丙烯酰胺（DMAM）、十六烷基二甲基烯丙基氯化铵（CDAAC）为单体合成出一种四元两性疏水缔合聚合物（PAADC），研究了其溶液的流变和减阻性能。考察了不同浓度该聚合物溶液的流变特性，讨论了该聚合物体系的摩擦阻力系数和减阻率随广义雷诺数的变化关系，并对比了PAADC与AM/AMPS/DMAM形成的三元水溶性聚合物（PAAD）的流变学和减阻效果。结果表明，聚合物体系具有良好的剪切稀释性，相同浓度PAADC溶液的触变性明显大于PAAD溶液；浓度为0.1%、0.2%、0.3%、0.4%的PAADC体系，最大减阻率分别为32.29%、62.32%、69.52%和67.35%，证明PAADC溶液浓度显著影响溶液的减阻性能，其中0.3%PAADC体系的减阻效果较优。

Abstract A hydrophobic amphoteric quadripolymer PAADC was synthesized for use as a drag reducer in slippery water fracturing fluids. PAADC, made from monomers AM, AMPS, DMAM and CDAAC, was studied in laboratory on its rheology and drag reduction capacity, and the rheology of PAADC solution at different concentrations is measured. Change of the friction coefficient and rate of drag reduction of the PAADC solutions with generalized Reynolds number is discussed in this paper. Comparison between the rheology and drag reduction capacity of PAADC and those of another water-soluble terpolymer PAAD (synthesized from AM, AMPS and DMAM) was conducted. PAADC solution has, as the studies indicated, very good shear thinning capacity, and the thixotropy of PAADC is better than that of PAAD at the same concentration. The maximum rates of drag reduction of PAADC solution of different concentrations (0.1%, 0.2%, 0.3%, and 0.4%) are 32.29%, 63.32%, 69.52% and 67.35%, respectively, indicating that PAADC concentration remarkably affects the drag reduction capacity of thesolutions, and 0.3% PAADC solution is preferred in drag reduction.

自1948年Toms[1]首先发现湍流减阻效应以来，高分子聚合物[2-4]和自组装表面活性剂[5-6]等减阻体系的研究获得广泛关注。疏水缔合聚合物的分子链中带有少量疏水基团，当溶液中聚合物浓度达到一定值之后，疏水基团趋向于发生分子间的疏水缔合，在溶液中形成网络结构，从而提高溶液黏度[7-9]，在油气田领域具有良好的发展前景，并且有望作为一种新型滑溜水压裂液体系[10-12]。……
