Sinofloc polyacrylamide flocculants has good performance in thickening, flocculation, and fluid rheology modifiers, which is widely used in drilling, plugging, water acidification, fracturing, wash well, completion, drag reduction, scale and drive oil . Currently many oil fields have entered the field of secondary, tertiary recovery, reservoir depth of 1000m above generally in some reservoir depth of 7000m, heterogeneity and offshore oilfield in oil production operations to the proposed more stringent conditions, deep oil and offshore oil corresponding to PAM also raised new demands to shear resistance, high temperature (above 100 ℃ up to 200 ℃), resistance to calcium ion, magnesium ion, seawater degradation. Our products show a good performance in Enhanced oil recovery (EOR). Partially hydrolyzed polyacrylamide (HPAM) is often used as drilling adjusting agent, which consists of polyacrylamide hydrolysis. Its role is to regulate the rheology of the drilling fluid t...
