Product Description

1/Drilling Fluid Additives

In drilling fluid additives,polyacrylamide is used as the drilling mud property adjusting agent whose function is to adjust rheological characteristic of drilling fluid,to carry rock fragments and to lubricate the drilling bit,and to increase drilling speed.Besides, it can largely reduce the sticking accidents,lighten the wear and tear of equipments and help regulate the holes diameter to avoid blow-out and well collapses,prevent formation damage during drilling.

2/Polymer Oil-displacing Agent

By means of add a certain amount of polyacrylamide into the injected waterand increase its viscosity to improve the oil-water mobility ratio.Polymer flooding is a kind of enhanced oil recovery method in the macro. It mainly depends on the increase flooding for liquid viscosity and reduce flooding for fluid and displaced fluid mobility for ratio, thereby expanding the swept volume; in micro, polymer due to its inherent viscoelastic, in flow process produced of oil film or oil droplets stretching effect, increasing the carrying capacity, improve the microscopic oil displacement efficiency.

3/Plugging Agent

In the process of oil field production, The water in the reservoir "breakthrough" and "channeling" phenomenon, reduce the effect of oilfield development,the need for timely water shutoff. The plugging essence is to plug the high permeability layer and the high yield water layer, adjusting the flow profile,reduce water production, and enhance the recovery ratio. As plugging agent,polyacryladmide have different impacts on filtration abilities of oil and water, less on oil and more on water.In application it can be used without cross-linking or cross-linked to gel in combination with aluminum, chromic salts or zirconium salts,etc. or added some resins to become interpenetrating polymer networks (IPN) with higher temperature resistance, IPN plugging agent cross-linked by W/O style PAM latex and modified amino resin has already been widely applied in oil field plugging and gotten obvious effects. PAM can be used in adjusting injection profile and blocking big holes, too and shows promising effects in practice.
