非牛顿液在地层裂缝中的物化流

PHYSIOCHEMICAL FLOW OF NON-NEWTONIAN LIQUIDS THROUGH FRACTURES IN RESERVOIR ROCKS

给出了泡沫酸沿井筒及地层裂缝流动的水动力学计算方法；建立了一套新的计算酸蚀缝宽，缝中压力分布，有效粘度计算模型。在求解泡沫酸的对流扩散方程时考虑了同离子效应：这些改进使得所编制的软件有较高的科学性。应用所编制的软件对四口井的酸化进行设计计算，其结果与实际施工结果完全吻合。

his paper presents a hydrodynamic calculation method for flowing of foamed acidthrough fractures in reservoir rocks. A series of new equations for the estimation of acide-thced fracture width,pressure distribution and effecrive vescosity in a fracture are esrab-lished. In solving the convection diffusion equation of aced concentration distribution,the in-fluence of commomn ion effect has been taken into account.Therefore the computer software worked in this paper is more accurate. Using these softwares,the design and calculation of an acidization job have been undertake for four wells, the results are idential with the results in the actual practice.
