This standard specifies the determination method of rheology of crude oil, including the definition of terms, sample preparation, four determination methods (swirl/spin method, thin tube method, porous media method, falling ball method) and requirements for test reports. It is suitable for evaluating the rheological characteristics of crude oil under different conditions. The standard covers key concepts such as rheology, shear rate, shear stress, dynamic viscosity and apparent viscosity, providing comprehensive guidance for the rheology analysis of crude oil. SY/T 5542-2009 (Method for Physical PropertyAnalysis of Oil and Gas Reservoir Fluids) is cited to ensure the scientific and Reliability of the determination method.
