Abstract

Recently, the polymer-nanoparticle combination has garnered significant interest in enhanced oil recovery (EOR) due to its promising experimental results. However, the previous research was mostly directed at silica, while alumina and zirconia nanoparticles have gotten the least consideration. Unlike previous works, this study aims to investigate the influence of three NPs: Silica (SiO2), Alumina (Al2O3), and Zirconia (ZrO2) on hydrolyzed polyacrylamide (HPAM). To this end, three nanocomposites were formulated: HPAM-SiO2, HPAM-Al2O3, and HPAM-ZrO2. Rheological evaluations were performed to examine the viscosity degradation of the three nanocomposites and HPAM under reservoir conditions. Furthermore, interfacial tension (IFT) at the oil–water interface and wettability studies were investigated. Moreover, sand-pack flooding was performed to examine the incremental oil recovery. The results revealed that the polymer viscosity was boosted by 110%, 45%, and 12% for HPAM-SiO2, HPAM-Al2O3, and HPAM-ZrO2 respectively under the investigation range of temperature. Moreover, the polymer viscosity was improved by 73%, 48%, and 12% for HPAM-SiO2, HPAM-Al2O3, and HPAM-ZrO2 respectively under the investigation range of salinity. Nanocomposites are also found to be a remarkable agent for reducing interfacial tension and changing the contact angle. The flooding experiments confirmed that the EOR by HPAM, HPAM-SiO2, HPAM-Al2O3, and HPAM-ZrO2, was 8.6%, 17.4%, 15.3%, and 13.6% of OOIP respectively. Moreover, the results of flooding experiments were well validated and matched by numerical simulation. Such findings of this work afford new insights into EOR and reinforce the promising outlook of such technique at the field scale.

储层条件下的纳米复合聚合物淹没综合研究:提高石油采收率的新见解
最近,聚合物-纳米粒子组合因其良好的实验结果而在提高石油采收率(EOR)方面引起了极大的兴趣。然而,以往的研究主要针对二氧化硅,而氧化铝和氧化锆纳米粒子则很少被考虑。与之前的研究不同,本研究旨在研究三种纳米粒子的影响:二氧化硅(SiO2)、氧化铝(Al2O3)和氧化锆(ZrO2)对水解聚丙烯酰胺(HPAM)的影响。为此,我们配制了三种纳米复合材料:HPAM-SiO2、HPAM-Al2O3 和 HPAM-ZrO2。流变学评估用于检查三种纳米复合材料和 HPAM 在储层条件下的粘度降解情况。此外,还研究了油水界面的界面张力(IFT)和润湿性。此外,还进行了砂包水淹,以检验增量采油。结果表明,在研究温度范围内,HPAM-SiO2、HPAM-Al2O3 和 HPAM-ZrO2 的聚合物粘度分别提高了 110%、45% 和 12%。此外,在盐度调查范围内,HPAM-SiO2、HPAM-Al2O3 和 HPAM-ZrO2 的聚合物粘度分别提高了 73%、48% 和 12%。纳米复合材料在降低界面张力和改变接触角方面也有显著作用。淹没实验证实,HPAM、HPAM-SiO2、HPAM-Al2O3 和 HPAM-ZrO2 的 EOR 分别为 OOIP 的 8.6%、17.4%、15.3% 和 13.6%。此外,数值模拟也很好地验证和匹配了淹没实验的结果。这项工作的这些发现为 EOR 提供了新的见解,并加强了这种技术在油田规模的应用前景。

期刊介绍: The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
