摘要: 酸化是油田解除近井地带污染、实现增产增注的主要措施之一。在基质酸化作业中,可通过不同时间测得的注酸排量q_i和井口注入压力P_(ti)数据,来监测基质酸化过程中表皮系数S的动态变化,实现对酸化过程的实时跟踪监测和评价。Abstract: Acidizing treatment is one of the main measures to remove near - well formation damage and realize incremental production and injection. During sandstone matrix acidizing treatment, the variation of skin factor can be monitored through measuring the acid discharge capacity and wellhead injection pressure with time, thus realizing real - time monitoring and evaluation of acidizing treatment.
