国内外现场试验证实,注聚合物驱油是三次采油中比较成熟的方法,目前已在油田矿场上较多使用。国外许多公司正在大力研究不同的聚合物体系,不断扩大现场试验规模,在他们所使用的种类繁多的产品中,有两类聚合物应用较广泛:①聚丙烯酰胺;②生物聚合物(黄原胶)。本文对聚合物的筛选和溶液的混配,稳定性试验,注入能力试验等进行了详细介绍,还对黄原胶在混配过程中的操作步骤和聚合物溶液的剪切处理做了说明。 Field experiments at home and abroad confirmed that injection of polymer flooding is a relatively mature method in tertiary recovery and is currently being used more often in oil fields. Many foreign companies are vigorously studying different polymer systems, expanding field trials, in their wide range of products used, there are two types of polymers are widely used: ① polyacrylamide; ② biopolymers glue). In this paper, polymer screening and solution mixing, stability test, injection ability test were introduced in detail, and the operation steps of xanthan gum in mixing process and the shearing treatment of polymer solution were also described.
