摘要
通过测量粉碎后的储层岩石在不同电解质溶液中及用各种酸化液处理后在水中的粒度分布变化规律,研究了水敏和酸敏中微粒释放趋势。对两种砂岩样的研究结果表明,各种无机和有机电解质对地层微粒释放趋势的抑制作用同岩石成分密切相关,用盐酸和土酸处理砂岩岩样后未见到微粒释放有增加的趋势。
The water sensitivity and/or acid sensitivity of reservoir can be investigated by determining the particle size distribution of core samples in various electrolyte solutions, or acid treated samples in water. It is found that the above method is accordance with the results of core chemical composition analysis. Fines releasing potential after acid treated of montmorillonite, kaolinite and two core samples is discussed.
