摘　　要：以室内实验为依据.讨论了含水原油的转相问题及温度、含水率对含水原油黏度的影响。河南油田特超稠油的黏度随着温度的升高呈指数式减小.黏度一温度曲线拐点在50℃左右。特超稠油转相点的含水率约为50%,在转相点以前,黏度随含水率的升高而增大;在转相点处,黏度达到最大值;在转相点后,黏度随含水率的升高而减小。因此,可通过升高储层温度降低原油的黏度,同时应避免含水率接近转相点的情况发生。It is discussed that the phase inversion point of wet crude oil, the temperature and water ratio influence to the viscosity based on the lab experiment. The viscosity of super heavy oil of Henan oilfield presentes decrease in exponent with the temperature rise, inflection point of the viscosity-temperature curves is at 50℃. The phase inversion point is about 50% of the water ratio. When the ratio is less than the phase inversion point, the viscosity is in direct proportion to the ratio, the ratio at the point, the viscosity is to maximum. When the ratio is above the point, the viscosity is inversely proportional to the ratio. Therefore, the viscosity can be decreased by the temperature raised, and the ratio is far away from the phase inversion point meanwhile.
