Application of polyacrylamide in oil field water plugging

In the process of oilfield production, due to the heterogeneity of formation, water flooding often occurs and water plugging is needed. Its essence is to change the permeability state of water in the formation, so as to reduce the oil field water production, maintain the formation energy and improve the ultimate recovery factor.

Application of polyacrylamide in oil field water plugging


In the process of oilfield production, due to the heterogeneity of formation, water flooding often occurs and water plugging is needed. Its essence is to change the permeability state of water in the formation, so as to reduce the oil field water production, maintain the formation energy and improve the ultimate recovery factor.

Among many drilling mud materials, polyacrylamide chemical water plugging agent has a selective effect on the permeability of oil and water, reducing the permeability of oil less, and reducing the permeability of water more. It can also be used with aluminum salt, chromium salt, zirconium salt and other cross-linking gels. Some resins can also be added to form interpenetrating polymer network (IPN) to make it have higher temperature resistance.

Using drilling mud materials such as polyacrylamide latex and modified amino resin, interpenetrating polymer network water plugging agent can be formed by chemical cross linking, which has been applied in oilfield water plugging and obtained obvious effect. The polyacrylamide produced by high quality polyacrylamide manufacturers can also adjust the formation water absorption profile and block large pores, and good results have been seen in practice.

As a widely used, high efficiency, widely used flocculant, polyacrylamide and its derivatives is a class of water-soluble polymers with a wide range of uses, which can be used as flocculant, paper strengthening agent, filtration loss agent, etc., has been used in water treatment, paper making, oil exploitation and other fields. The crosslinked polymer can be used as soil water retaining agent and oil field water blocking agent because of its properties of water absorption, tax declaration and swelling.

In addition, polyacrylamide can be used as an additive for fracturing fluids. Fracturing is an important stimulation method for tight formation development in oil fields. Its role is to open rock channels to allow oil to flow through. Methylene polyacrylamide crosslinked fracturing fluid is widely used because of its advantages of high viscosity, low friction resistance, good sand suspension ability, convenient preparation and low cost.

At present, not only the government mud, the country's major polyacrylamide manufacturers are facing this good opportunity. Polyacrylamide also plays a decisive role in the major drilling mud materials, but also has considerable competitiveness, its market potential can not be underestimated!
