Confront with the problem of effective layout of acid and the problem of second damage of silica gel during reaction of acid with mineral in high temperature heterogeneity sandstone reservoir, this article firstly put forward develop amphoteric viscoelastic surfactant micelle acid used for diversion acid in high temperature heterogeneity sandstone reservoir, successfully developed sinapic amido propyl betaine micelle acid which own the property of self-diverting; systematic established coupling kinetics model of flowing and reaction of acidizing in high temperature reservoir firstly, realized repeat reproduce of the reaction process of reaction of acid with mineral, quantized silica gel and ascertained its location, established optimal design method of acidizing in high temperature heterogeneity sandstone reservoir; In the same time, established micelle gel diversion model and real-time monitoring model which can response the working state of diverter and other working fluid, formed sandstone micelle acid diversion acidizng technology.
针对高温非均质砂岩储层酸化时酸液有效置放困难、高温砂岩酸岩反应过程中会出现水合二氧化硅沉淀及二次伤害明显的问题，本文首次提出采用抗高温体系的两性粘弹性表面活性剂研制适用于高温非均质砂岩储层分流酸化的变粘胶束分流酸，成功研制出了在高温砂岩储层中具有自转向功能的芥子酰胺丙基甜菜碱变粘胶束分流酸；首次系统地建立了高温砂岩酸化流体流动与化学反应耦合动力学模型，用计算机程序实现了高温酸岩反应过程的重复再现，量化这种水合二氧化硅和确定了其产生的位置，建立了优化高温砂岩储层酸化设计参数的方法；同时建立了胶束凝胶分流模型和能反映包括分流剂在内的各种工作液工作状况的实时间监测模型，形成了砂岩胶束分流酸酸化技术。
