The petroleum industry relies on advanced chemical technologies to optimize oil extraction and improve recovery rates. Polyacrylamide (PAM), a versatile water-soluble polymer, plays a significant role in these processes, particularly in enhanced oil recovery (EOR) and as a drilling fluid additive. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-performance polymers that are critical to these demanding applications, including Nonionic Polyacrylamide (NPAM).

In Enhanced Oil Recovery (EOR), polymers like PAM are injected into oil reservoirs to increase the viscosity of the displacing fluid (typically water). This higher viscosity improves the sweep efficiency, meaning more oil is pushed towards the production wells. NPAM, with its ability to modify fluid rheology, is highly effective in this role. It helps to reduce the mobility ratio between the injected water and the reservoir oil, preventing viscous fingering and channeling, which are common issues that limit oil recovery. The industrial applications of PAM in oil extraction are substantial, contributing to increased hydrocarbon yield.

Furthermore, polyacrylamide is utilized as a friction reducer in hydraulic fracturing operations. By minimizing frictional losses as the fracturing fluid is pumped downhole, it reduces the energy required for pumping and allows for higher injection rates. This leads to more efficient fracturing treatments and potentially greater well productivity. The properties of Nonionic Polyacrylamide that contribute to its effectiveness include its high molecular weight and its ability to form stable solutions that efficiently reduce friction.

In drilling operations, PAM serves various functions, including as a shale stabilizer and a viscosity modifier for drilling muds. Its ability to adsorb onto clay surfaces helps to prevent shale swelling and dispersion, which can lead to wellbore instability. As a viscosity modifier, it helps to suspend cuttings and prevent them from settling when circulation is lost. While different types of PAM are used, the principles of how to use polyacrylamide remain consistent: ensuring proper dissolution and concentration for optimal performance.

The choice of polyacrylamide for oilfield applications often depends on the specific conditions of the reservoir, such as temperature, salinity, and shear rates. While NPAM offers broad applicability, specialized formulations of PAM may be optimized for extreme conditions. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality PAM products that meet the rigorous demands of the petroleum industry, supporting efficient and cost-effective extraction operations.
