摘要
岩石矿物颗粒的酸溶蚀是油气井酸化增产技术中的重要问题。本文针对受扩散传质控制和表面反应控制时的酸岩反应情形,通过将当代数学新理论-分形几何学引入酸岩非均相反应系统,提出了酸岩二维反应分形模型,据此在一定程度上考察了岩矿颗粒表面复杂结构对酸溶蚀速率的相对影响。
Abstract
Pickling of rock is an important problem in acidizing of oil and water wells.According to the acid-rock reaction controlled by diffusion mass transfer and surface reaction,this paper presents 2D model of acid-rock reaction by applying the new theory of mathemetics-fractal in acid-rock heterogeneotis reaction system,and then analyses the influence of complex structure of rock grain on pickling rate to a certain extent.
