摘　　要：通过测试不同阳离子乳化沥青浓度的钻井液在4个温度点下的表观粘度、塑性粘度和动切力,分析阳离子乳化沥青对钻井液流变性的影响。试验结果表明,浓度在4%以下时,阳离子乳化沥青对钻井液各流变参数的影响较小,且影响为非线性。阳离子乳化沥青的加入,并没有质变性地影响温度对钻井液流变性的作用。By testing fluid apparent viscosity, plastic viscosity and dynamic shear force of drilling fluid with different concentrations of cationic emulsified asphalt at four different temperature point, the influence of cationic emulsified asphalt on the rheology of drilling fluid was analyzed. The results show that, when cationic emulsified asphalt concentration is below 4%,it has less influence on the each rheological parameters of drilling fluid,and the influence is nonlinear. Cationic emulsified asphalt doesn＇t impact the influence of temperature on the rheological properties of the drilling fluid qualitatively.
