摘要
本文研究了磁化处理对钻井液某些性能的影响,包括粘土阳离子交换容量、岩心渗透率、表观粘度、塑性粘度、动切力等的改变。钻井液经磁化后对粘土水化膨胀的抑制性提高,一些流变性得到改善。
The cation exchange capacity of clay in aqueous suspensions,the permeability of core after flow tests,the apparent and plastic viscosities and yeild stress of drilling fluids are determined before and after the test fluids are treated magnetically.It is shown that magne- tization enhances the inhibition of clay hydration and swelling and improves some charac- teristics of the drilling fluids.
