塔河油田稠油粘度特性试验研究

应用高温高压流变仪，在不同温度和压力下，对塔河油田TK427井产原油进行了试验研究，测量了不同含水率、不同气油比下的原油粘度，用曲线拟合法探讨了原油及油气水多相流粘度与温度、压力不同的关系，结果表明原油及油气水多相流的粘温特性符合指数规律，原油粘度与压力呈线形关系，原油的粘度随气油比不同而变化巨大，含气原油粘度随压力变化存在极小值(泡点压力)，含水原油粘度随含水量变化存在极大值(非乳化拐点)。

Experiment on Viscosity Properties of Viscous Crude Oil in Tahe Oilfield

Under the different temperature and pressure, the viscosity was measured of the viscous crude oil from the TK427 well supplied by Tahe oilfield and its mixture that the water-cut and gas content are different with high temperature and high pressure viscosimeter. The relationship between the viscosity of the crude oil and its mixture and the temperature or the pressure was discussed with curve-fitting method. It indicates that the viscosity and temperature character fit to exponential law, the viscosity is linear transformation with the pressure. The gas content strongly influences the viscosity of the crude oil. The viscosity of the gas-oil has a minimal value varying with the pressure, and the viscosity of the water-bearing oil has a maximal value varying with the water-cut.
