摘要
本文利用碱水驱替动力学实验测定流出物中主要离子含量,分析产生碱耗的各种因素,求出了可逆反应与不可逆反应的碱耗速率。本文提出的实验方法可用于预测地层注碱效果及判断注碱水方案的可行性。
A laboratory continuous alkaline flooding experiment is performed on the oily sand with the formation water from Dagang Oil Field at 62℃.From the determinatlons of OH^-,K^+, Na^+ and Si^(4+) in the flowing-out solution at definite intervas of time,the changes of each ion with time are analyzed in terms of the factors connected with the alkaline consumption, and thus the rates of both reversible and irreversible alkaline consumption reactions can be calculated.This experimental approach is useful for predicting successfulness and feasibility of an alkaline flooding program prior to its carrylng-out.
