对胜利油田附近六个造纸厂的黑液性质进行了室内试验研究,其中包括固形物含量、pH值、碱含量、表面张力、界面张力、润湿性、流变性、腐蚀性、相对密度、冰点、木素含量和稳定性等.研究认为,碱法造纸黑液的固形物含量低,其主要成分是碱、碱木素和活性剂.根据黑液的这些性质提出了碱法造纸黑液在驱油、调剖、稠油降粘、注水井解除油堵等方面应用的可行性. Laboratory tests on the properties of black liquor in six paper mills near Shengli Oilfield were carried out, including solid content, pH value, alkali content, surface tension, interfacial tension, wettability, rheology, corrosivity, relative density, freezing point , Lignin content and stability, etc. It is considered that the low solid content of alkali papermaking black liquor is mainly composed of alkali, alkali lignin and active agent.According to these properties of black liquor, Flooding, profile control, heavy oil viscosity reduction, water injection wells and other aspects of the feasibility of the application of oil plugging.
