携砂液在裂缝中的流动阻力理论分析

The paper studies the flow characteristics of propladen fluid in vertical hydraulic fracture.At first,the velocity of fluid flow can be derived from the mechanism of fracture fluid laminar flow and the distributed principle of the fluid pressure in the fracture.And then,the apparent viscosity of propladen fluid is calculated reduce based on the kinetic theory of propladen fluid together applying Thomas's law.Furthermore,by studying the interaction between the wall of fracture and proppant,we can setup the formula which presents the flow resistance of propladen fluid in hydraulic fracture,so that the capability of different proppant concentration and the grain size can be accessed.The paper provides a theoretical method for the further study in propladen fluid flow resistance in hydraulic fracture.
