Method for determining dynamic viscosity of flow of suspension of hydrates formed in mixture of water and oil circulating in pipe, involves defining law of agglomeration, and determining parameter characteristic by using law and parameters

摘要

The method involves defining a law of agglomeration of hydrates to connect a state of agglomeration of the hydrates to stress by a suspension. Parameters are determined by circulating a mixture of water and oil, and gradually lowering temperature of the mixture until formation of a stable suspension of the hydrates and by measuring pressure loss induced by the formation of the stable suspension of the hydrates. A parameter characteristic i.e. dynamic viscosity, of the flow of the suspension of hydrates is determined by using the defined law and the determined parameters.
