| In this thesis, quantum mechanics was applied to the area of Surface/Polymer flooding liquid porous flow mechanisms and Theological behavior for the first time. The porous flow mechanisms and rheological behavior of Surface/Polymer flooding liquid have been studied, a few quantum mechanics’ application in surface/polymer flooding were researched.Based on experimental study of Surface/Polymer flooding liquid’s rheological behavior, when shear rate rised, surface/polymer flooding liquid’s apparent viscosity went up firstly, then went down and approached a certain nember. In the process of preparing solution, Weissenberg effect was found. The porous flow mechanism of Surface/Polymer flooding liquid was studied with the experiment of flow in cores. The porous flow had the feature of Darcy’s flow when the permeability was high and the viscosity was low. With the reduction of permeability and rise of the viscosity, the porous flow flow had more obvious feature of nonlinear. When the pressure gradient was low, Surface/Polymer flooding’s flow was like Darcy flow or Non-Darcy flow with the threshold pressure gradient.The fluid was studied regarded as Probability Wave according to quantum mechanism. Schrdinger equation was used in redial direction. Quantum rheological equation was deduced that it can explain Surface/Polymer flooding liquid’ s rheological behavior and Weissenberg effect, methods of quantum mechanics and thermodynamics are taken into the fluid mechanics in porous medium. Quantum porous flow equation was deduced that it explained Surface/Polymer flooding system porous flow mechanism. The equation showed the porous flow is nonlinear flow. Darcy linear flow and Non-Darcy flow with the threshold pressure gradient were the approximations of quantum flow equation.According the quantum flow equation, injection of Surface/Polymer should use the way of injection alternatively of high and low viscosity fluid. |
