摘要
阐述了pH值对基液配制、交联冻胶的形成、细菌的生产繁殖和压裂后滤液造成的粘土膨胀的影响。认为在配制基液时 ,先调pH值为弱碱性 ,不仅有利于基液的快速分散 ,而且对抑制细菌的生产繁殖也有很大作用。正确把握pH值的作用 。
A kind of fracturing fluid named aqueous cross-linked gelled fracturing system h as be presented,the form process of aqueous-based and cross-linked gel require t he condition under a certain PH value.The study of PH value's influence on the f racturing system is very important.The influence of PH value on aqueous-based c o nfect and form,bacteria's propagate and clay swell has been discussed in detail. The conclusion gotten is as follows: If the PH value preserves weak alkali,it wi ll not only benefit to the dispersion of the aqueous-based,but also benefit to t he process of the restrain bacteria' propagate.As a whole,the proper control PH value can play an important role to deal with problems encountered in the proces s of liquid confect.abstract
