Sinofloc Polyacrylamide Used As Oil Field Additives

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 to carry cuttings, lubricate the drill bit, and reduce fluid losses. The proportion of the drilling fluid polyacrylamide modulated low, reduce reservoir pressure and clogged, easy to find oil and gas layer and facilitates drilling, drilling speed than conventional drilling 19% higher than the penetration rate is about 45% higher. Additionally, it can greatly reduce sticking accidents, reduce equipment wear and tear, and can prevent the occurrence of lost circulation and collapse. Fracturing stimulation is an important field development dense layer. Polyacrylamide crosslinked fracturing fluid, because of its high viscosity, low friction, and good ability of suspended sand, fluid loss, good viscosity stability, less residue, wide supply, convenience and cost formulation low is widely used.

AMPs acrylamide copolymers have better resistance to temperature, decrease fluid loss and salt resistance in fresh drilling mud, saltwater drilling fluids, drilling fluids and seawater saturated brine drilling fluids.
