Applications in the oilfield sector

1.Three oil recoveries

When the oilfield enters the tertiary oil recovery period, the ripple coefficient of the injection solution is increased by injecting a viscous polymer solution to block the large channel, and each ton of polymer can produce 120 to 150 tons of crude oil for the user. The company's polyacrylamide products for tertiary oil production in oilfields are now widely used in Daqing, Shengli, Dagang, Liaohe, Xinjiang, Henan, North America, South America, India, the Middle East, Russia and other oilfields.

2.Adjust the water to block the water

The water is to add a crosslinking agent to a certain concentration of polyacrylamide solution, so that the high-valent metal ions in the crosslinking agent are coordinated and bound with the carboxyl group in polyacrylamide in the form of polynuclear hydroxyl bridge polyions. 

Use with crosslinkers increases gel strength and blocks pores.

3.Drilling fluids

Polyacrylamide is used as an oilfield drilling fluid to improve drilling fluid performance, prevent well wall collapse, cool drill bits and lubricate drill bits, and suppress wall collapse. Polyacrylamide for drilling fluids can be applied to low solid phase non-dispersible polymer drilling fluid systems, can be used in combination with a variety of treatment agents, and is suitable for various mud systems.

Features: 

1. Shale inhibitors: inhibit the hydration, expansion and decomposition of clay minerals contained in shale to prevent well collapse

2. Filtration loss: controlling water entering the formation leads to hydration and expansion of mud shale

3. viscosity reduction: concentrated on protecting the edge of clay particles, enhance the negative electrical effect at the place, so that the system can not form a grid structure and thus play a role in reducing viscosity.

4. Fracturing fluid thickener

In the low-permeability oil layer of the oilfield, the formation is pressed open by pressure, a crack is formed and supported by a proppant to reduce the resistance of fluid flow to achieve the purpose of increasing production and attention. After crosslinking, the fracturing fluid thickener can send a high content of proppant into the crack, playing the purpose of supporting the crack, and this product has good shear resistance and thermal stability.

5. Oilfield drag reducer

Polyacrylamide drag reducer is widely used in crude oil and refined oil pipeline transportation, the frictional resistance of the fluid in the pipeline limits the flow of the fluid in the pipeline, resulting in a decrease in pipeline transportation and energy consumption, the drag reducer is an important means to improve the pipeline circulation capacity and reduce energy consumption in a specific area. Our polymer resistive agents effectively reduce flow resistance while also inhibiting pipe corrosion.

Use and dosage of inhibitors

Usage: The inhibitor is dissolved in a small amount of water and stirred to dissolve it evenly, and then gradually injected into the pipeline to make it mixed with the level in the pipeline. The injection speed should not be too fast, otherwise it will cause a traffic gradient. Dosage: 1m3 liquid add about 3kg of this inhibitor.
