摘　　要：为研究稠油乳状液在实际管道中的流动特性,弥补流变仪等仪器的缺点,研制了一种试验环道装置。利用该装置对胜利陈南稠油乳状液进行了输送试验,模拟了稠油乳状液在管道中的实际流动情况,并与流变仪测试结果进行对比。试验表明:含水率对稠油乳状液黏度影响很大,含水率高于40%时出现转相点,最佳含水率为45%;乳状液输送存在一个最佳混合流速,流速过高乳状液表观黏度有增大趋势;稠油乳状液表观黏度随温度的升高而减小,温度对O/W型稠油乳状液表观黏度的影响很小;在相同实验条件下,流变仪测试结果与环道试验结果规律一致,但表观黏度值偏小。In order to study the flow characteristic of heavy oil emulsion in the actual pipeline and to make up for the shortcomings of rheology instrument,a test loop device is developed. The authors used this device to carry out transporting test for the heavy oil of Chennan in Shenli,and simulated the actual flow characteristics of heavy oil emulsion in the pipe. The test results were compared with that of the rheometer. The influence regularity of water content,mixed flow velocity and temperature on the viscosity of emulsion pipe were obtained. Experiments show that： the water content has a great influence on the viscosity of heavy oil emulsion. When the water content is greater than 40%,the phase transition point appears. There is an optimum water content which is 45%. Besides there is an optimum mixture velocity. When flow rate is too high the emulsion viscosity increased. Heavy oil emulsion viscosity decreases with the increase of temperature,but the temperature has little effect on the viscosity of O / W type emulsion. Under the same experimental conditions,the test results of the rheometer agree with the test results of this test loop device,but the apparent viscosity of using rheometer is a little smaller.
