Viscosity: viscosity is the crude oil in the flow caused by the internal frictional resistance, crude oil viscosity depends on temperature, pressure, dissolved gas and its chemical composition.
粘度：原油粘度是指原油在流动时所引起的内部摩擦阻力，原油粘度大小取决于温度、压力、溶解气量及其化学组成。
The frictional resistance factor increases with the increase of the flow velocity, decreases with the increase of temperature and its variation law with the pressure is complicated.
摩擦阻力系数随着流速增大而增大，随着温度的升高而减小，而其随着压力的变化特别复杂。
