The oil and gas industry continuously seeks innovative methods to maximize hydrocarbon recovery from existing reservoirs. Enhanced Oil Recovery (EOR) techniques are crucial in this endeavor, and among the key chemical agents employed, polyacrylamide (PAM) plays a significant role. At NINGBO INNO PHARMCHEM CO.,LTD., we provide specialized polyacrylamide products tailored for sophisticated oilfield chemicals polyacrylamide usage aimed at improving extraction efficiency.

Polyacrylamide, particularly in its partially hydrolyzed form and often as a cationic or anionic polymer depending on the reservoir conditions, is primarily used in EOR through polymer flooding. This method involves injecting a high-viscosity polymer solution into the oil reservoir. The primary objective is to increase the viscosity of the injected water, thereby improving the sweep efficiency of the water flood. In a conventional water flood, lower-viscosity water tends to bypass more viscous oil, leaving a substantial amount of oil unswept. By increasing the viscosity of the injected water, polymer flooding ensures that the water front moves more uniformly through the reservoir, displacing more oil towards production wells.

The efficacy of PAM in EOR is directly linked to its rheological properties, specifically its high molecular weight and shear stability. A high molecular weight allows the polymer to create a significant increase in viscosity with relatively low concentrations. Shear stability is important because the polymer solution must withstand the shear forces encountered as it flows through the porous rock formations and pumping equipment without significant degradation. NINGBO INNO PHARMCHEM CO.,LTD. offers polymer grades specifically engineered for these demanding conditions, ensuring optimal performance and longevity in the reservoir.

The application of PAM in oilfields extends beyond polymer flooding. It can also be used as a friction reducer in drilling fluids, which helps to decrease the energy required for pumping and reduces wear on drilling equipment. In some cases, PAM derivatives are used in fracturing fluids to control viscosity and improve the transport of proppants to keep fractures open after the fracturing treatment. These diverse applications underscore the versatility of oilfield chemicals polyacrylamide usage in optimizing various stages of hydrocarbon extraction.

Selecting the correct polyacrylamide for EOR requires careful consideration of reservoir characteristics such as temperature, salinity, shear rates, and the presence of other ions. NINGBO INNO PHARMCHEM CO.,LTD. provides technical support to help clients choose the most appropriate PAM product, whether it's a high molecular weight anionic PAM for low-salinity reservoirs or a specific copolymer designed for high-temperature or high-salinity environments. Our commitment is to deliver solutions that enhance oil recovery rates and improve the economic viability of mature oil fields.

As the global demand for energy continues, the importance of effective EOR techniques, supported by advanced chemical solutions like polyacrylamide, will only grow. NINGBO INNO PHARMCHEM CO.,LTD. remains dedicated to supplying the oil and gas industry with the high-performance polymers needed to meet these critical objectives, contributing to efficient resource extraction and production optimization.
