Enhanced Oil Recovery (EOR) is critical for maximizing the output from mature oil fields. Among the various EOR methods, polymer flooding has proven to be highly effective, and at its core lies the use of polyacrylamide. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing polyacrylamide grades essential for these advanced recovery operations.

The fundamental principle behind polymer flooding is to increase the viscosity of the injected fluid, thereby improving the sweep efficiency of the oil reservoir. When polyacrylamide is added to injection water, it significantly boosts the water's viscosity. This makes the injected water front more viscous and less prone to bypassing oil in low-permeability zones. The polyacrylamide polymer molecules effectively 'sweep' the oil through the reservoir, reducing the unfavorable mobility ratio between oil and water. This ensures that more oil is displaced towards the production wells.

Polyacrylamide's effectiveness in EOR stems from its unique properties: thickening, flocculation, and adsorption. Its thickening effect increases the viscosity of the driving fluid, which is paramount for improving oil displacement. The flocculation properties help aggregate fine particles, aiding in smoother flow. Moreover, polyacrylamide's ability to adsorb onto reservoir rock surfaces can help control water flow, directing it towards oil-rich areas and further enhancing recovery. The careful selection of polyacrylamide, considering factors like molecular weight and charge density, is key to optimizing performance for specific reservoir conditions. NINGBO INNO PHARMCHEM CO.,LTD. offers expertise in selecting the right polyacrylamide for maximum impact in your EOR projects.

The development of more robust polyacrylamide formulations, such as those resistant to high temperatures and salinity, is vital for application in diverse reservoir environments. As the oil industry pushes the boundaries of extraction, the demand for specialized polyacrylamide solutions will only grow. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to meeting these evolving needs, providing high-quality polyacrylamide that contributes to efficient and sustainable oil production, reinforcing our position as a premier supplier in China and internationally.
