Product performance：
In the fracturing and acidification treatment, the polyacrylamide flocculant is formulated with a concentration of 0.5%.01% to 4% of the aqueous solution is pumped into the underground formation to fracture the formation.The aqueous solution of polyacrylamide flocculant has the effect of thickening and carrying sand and reducing the flow of fracturing fluid.Moreover, polyacrylamide has a drag-reducing effect, which can reduce the pressure transfer loss.
1. As an acidification and fracturing thickener, it is mainly used in the development of carbonate rock reservoirs.Due to the development of holes and crevices in carbonate rock reservoirs and the high formation temperature, to ensure the effect of acid pressure transformation, it is necessary to increase the penetration depth of acid pressure cracks in the reservoir and improve the diversion capacity of acid erosion cracks. Therefore, adding a thickener to the acidification fracturing system can delay the reaction speed of acid liquid and stratigraphic rocks, increase the spread coefficient, improve the sand carrying capacity, reduce filtration loss, and achieve the purpose of increasing production and injection.
2.As a drag reducer for fracturing, in the operation of increasing production in oil fields, the fracturing fluid is transported through the pump under high pressure and high flow rate conditions to a depth of about 500 meters to 6000 meters or deeper drilling, causing the rock formation around the borehole to crack.Drag reducer reduces the resistance during migration by increasing the viscosity and reducing turbulence in the fracturing fluid.
