【摘要】 本文通过测定聚合物泥浆的喷嘴粘度（η_∞）、结构强度（τ_c）及聚合物在粘土上的吸附量（Γ）,分析、论证了在极高速梯(10万s^-1)下,粘土和聚合物间相互作用及其对泥浆流变性的影响,从而为体系流变性的调节找到一种有效的途径,并对聚合物泥浆稀释剂及其稀释机理提出了新的看法。更多还原

【Abstract】 By means of measuring polymer mud bit nozzole viscosity（η_∞）,structural strength（τ_c） and polymer adsorbance（τ）on clay as well as analysing these data,it is proved that under the condition of the high rate gradient(100000 s^-1) the mutual effect between clay and polymer and its influence on mud rheological properties exist,hence a effective way to adjust mud rheological properties is found. A novel point of view about polymer mud thinner and thinning mechanism is also presented.更多还原
