The additive drag reduction technology has wide application and high economic value in drag reduction of oilfield water injection system. With CTAC/NaSal (cetyltrimethyl ammonium chloride/sodium salicylate) aqueous solution as the research object, this paper explores the effects of oilfield water component on its rheological characteristics under the experimental condition of 10–60°C, .1–1 000 s⁻¹, and 0.01–0.21 wt %. The experimental results reveal that the oil cannot inhibit the formation of shear‐induced structure in the solution and strengthen the temperature resistance of the solution; NaHCO₃ and CaCl₂, two types of salts, have similar effects on rheological characteristics of the CTAC/NaSal solution. The solution viscosity increases first and then decreases with the increase of salt concentration. And the viscosity peak gradually moves to the left lower with the increase of temperature, which means that the salt tolerance of the solution decreases with the increase of temperature. Moreover, the Giesekus model has the best performance for describing the rheological characteristics of surfactant solutions. Within the experimental concentration range, the relative error is ±25%.

油田注水成分对CTAC / NaSal水溶液流变特性的影响

添加剂减阻技术在油田注水系统减阻方面具有广泛的应用价值和较高的经济价值。与CTAC /鼻（十六烷基三甲基氯化铵/水杨酸钠）水溶液为研究对象，探讨10-60℃，.1-1 000秒在实验条件下油田水成分的在其流变学特性的影响^{- 1}和0.01–0.21 wt％。实验结果表明，该油不能抑制溶液中剪切诱导结构的形成，并不能增强溶液的耐热性。NaHCO ₃和CaCl ₂两种盐对CTAC / NaSal溶液的流变特性具有相似的影响。溶液粘度先增加，然后随着盐浓度的增加而降低。随着温度的升高，粘度峰值逐渐向左下方移动，这意味着溶液的耐盐性随着温度的升高而降低。此外，Giesekus模型在描述表面活性剂溶液的流变特性方面具有最佳性能。在实验浓度范围内，相对误差为±25％。
