摘要：

为研究MEOR过程中注入激活剂在地层中的运移及多孔介质对激活剂的影响，进行了不同激活剂在填砂岩心和含油岩心中的运移实验，并考察了激活剂在不同注入速度、注入浓度条件下的运移堵塞情况。结果表明，在玉米浆、葡萄糖、淀粉3种主激活剂中，岩心多孔介质对葡萄糖的运移影响程度最小。但由于玉米浆廉价且具有较好的激活效果，所以将玉米浆作为进一步考察对象，实验表明玉米浆浓度为10 g·L^-1、注入速度为1. 2 ml·min^-1是适合的注入条件。同时实验还表明在填砂岩心中要比在含油岩心中对激活剂运移的影响大。

Abstract:

In order to explore the activator migration through porous media in MEOR process，the flooding experiments of different major activators in filled sand cores and crude oil saturated cores were performed. In addition，the migration of activator with different injection rate and concentration in the cores were also investigated. Results showed that clogging of the cores is the lowest with glucose compared with corn slurry and starch solution. For the low price and good activation effect，corn slurry was studied further，the suitable injection conditions of which were found to be 10 g·L^-1of concentration and 1.2 ml·min^-1of injection rate. The activator migration in crude oil saturated cores is more smooth than that in filled sand cores.
