Poliacrilammide del giacimento petrolifero Produttori

Nell'area di sfruttamento del petrolio, la poliacrilammide viene utilizzata nel processo di perforazione e nel processo di recupero del petrolio. Nel processo di perforazione (perforazione di pozzi, completamento di pozzi e cementazione di pozzi), la poliacrilammide viene utilizzata nel fluido di perforazione, nel fluido di completamento e nel fluido di cementazione. Nel processo di recupero del petrolio (fratturazione e recupero intensificato del petrolio), la poliacrilammide viene utilizzata nel fluido di fratturazione e nell'agente di allagamento del polimero.

Feedback sul messaggio
Polyacrylamide is a multifunctional oilfield chemical treatment agent widely used in the petroleum industry. Technological advances in polyacrylamide polymers have accelerated the development of the petroleum industry, and the needs of the petroleum industry have accelerated the timely innovation and development of polyacrylamide polymers.
The role of polyacrylamide in oil and gas:
1.Improve Oil Recovery: Polyacrylamide as a thickener can increase the viscosity of water and oil. Improving the water-oil flow ratio, to form a high-viscosity oil displacing agent. Promoting the flow of crude oil in oil wells, so that more crude oil is driven out and the recovery rate is increased.
2.In tertiary oil recovery, one of the most widely used applications is ultra-partially hydrolyzed high molecular weight polyacrylamide (HPAM). High-viscosity polyacrylamide (HPAM) solution can improve the oil driving efficiency and reduce the residual oil saturation. High concentration of polyacrylamide can increase the recovery by more than 20% on the basis of water drive, and overcome the defect of alkali contamination to the formation.
3.Water treatment:  Wastewater generated in the process of oilfield mining (oily wastewater) needs to be treated before discharge or reuse. Polyacrylamide is widely used as a flocculant in oilfield wastewater treatment. It can quickly settle suspended solids and sediments in the water, , reduce the clogging and siltation of oil wells. And improve wastewater treatment efficiency and water quality. Reducing the maintenance cost and cleaning cycle, and extend the service life of oil wells. Oilfield sewage treatment, polyacrylamide is an important class of synthetic organic polymer flocculants. Compared with traditional inorganic flocculants, polyacrylamide has the advantages of more varieties, high flocculation efficiency and less sludge generation.
4.Fracturing fluid: In oil and gas field fracturing operation, polyacrylamide is used as thickening agent for fracturing fluid to increase the viscosity of the fracturing fluid, so that it can bring fracturing sand into the fracture more effectively. And keep the fracture open to increase oil and gas production.
5.Gas Dehydration: Polyacrylamide can be used as part of the dehydration process to remove water from natural gas to prevent pipeline corrosion and ice jams, which greatly enhances the efficient transmission and storage of natural gas.
6.Environmentally friendly: Compared with traditional chemicals, polyacrylamide degrades faster, it doesn't bring persistent pollutants to the environment.
7.Drilling fluids: Polyacrylamide can be used as an additive of drilling fluid, lubricate the drill bit, which is favorable for drilling, improve the viscosity and suspension performance of drilling fluid, help carry the drill cuttings back to the surface, reduce the loss of drilling fluid, and protect the oil and gas layer during the drilling process. It can also greatly reduce stuck drilling accidents, reduce the wear of equipment, and can prevent the occurrence of well leakage and collapse, so that the well diameter rules
Polyacrylamide has made a good contribution to the development of oil and gas engineering. It is an indispensable chemical additive in oil and gas extraction. In practical application, choosing the right type and model of polyacrylamide can further optimize its effect according to different reservoir characteristics and extraction processes.

How is polyacrylamide used in drilling fluids, completion fluids, and cementing fluids?
1. Drilling Fluids:
Oilfield Polyacrylamide is a key component in drilling fluids, which are essential for the drilling process. Drilling fluids serve multiple purposes, including cooling the drill bit, carrying cuttings to the surface, and stabilizing the wellbore. Polyacrylamide is added to drilling fluids to modify their rheological properties. It enhances viscosity, improves filtration control, and inhibits shale hydration. The increased viscosity aids in better cuttings suspension and transport, preventing clogging and ensuring smoother drilling operations.
2. Completion Fluids:
In the well completion phase, where the well is prepared for production, polyacrylamide is employed in completion fluids. These fluids are designed to control reservoir damage and ensure the wellbore is ready for efficient production. Polyacrylamide contributes to the stability of completion fluids, aiding in zonal isolation and preventing formation damage. Its use helps maintain the integrity of the well and enhances the overall productivity during the production phase.
3. Cementing Fluids:
Oilfield Polyacrylamide finds application in cementing fluids used during well cementing operations. Well cementing is critical for securing the casing in place and preventing fluid migration between different geological formations. Polyacrylamide in cementing fluids improves the fluid's properties, providing better control over cement slurry rheology. This contributes to effective zonal isolation, ensuring a reliable and secure wellbore structure.

How does polyacrylamide impact the viscosity and filtration control of drilling fluids?
1. Enhancing Viscosity:
Viscosity is a critical parameter in drilling fluids, influencing their ability to carry cuttings, suspend solids, and maintain wellbore stability. Oilfield Polyacrylamide is added to drilling fluids to enhance viscosity, providing several benefits. Increased viscosity aids in improving hole-cleaning efficiency by preventing cuttings from settling and accumulating at the bottom of the well. This results in better cuttings transport to the surface, reducing the risk of wellbore instability and equipment damage. Polyacrylamide's contribution to viscosity is particularly valuable in challenging drilling conditions, such as high-temperature and high-pressure environments.
2. Controlling Filtration:
Filtration control is another crucial aspect of drilling fluid performance. As drilling fluids circulate through the wellbore, they encounter various formations and rock types. Polyacrylamide helps in controlling filtration by forming a thin, impermeable filter cake on the wellbore wall. This filter cake acts as a barrier, preventing the invasion of drilling fluids into the formation and minimizing formation damage. By regulating filtration, polyacrylamide ensures efficient wellbore stability, reduces fluid loss, and enhances overall drilling success.
3. Shale Inhibition:
Oilfield Polyacrylamide also plays a key role in inhibiting shale hydration, which is a common challenge in drilling operations. Shale hydration can lead to wellbore instability and difficulties in maintaining hole integrity. The addition of polyacrylamide to drilling fluids helps mitigate shale hydration by forming a protective barrier around shale particles. This inhibition contributes to the prevention of wellbore collapse, minimizing downtime and optimizing drilling efficiency.
