摘要
部分水解聚丙烯酰胺 (HPAM) Cr(Ⅲ )凝胶已在油田广泛应用 ,是一类有效的调剖堵水剂 ,对于调整吸水剖面和提高原油采收率起到重要作用。本文简要概述HPAM Cr(Ⅲ )交联反应机理的研究方法 ,如粘度法、紫外 可见吸光光度法、原子力显微镜 (AFM)、激光光散射法、原子吸收法等 。
Water based gels,comprising partially hydrolyzed polyacrylamide (HPAM) cross\|linked with chromium (Ⅲ),are now finding widespread use for near well\|bore water and gas shut\|off in the oil industry.The study on the mechanism and kinetics of the cross\|linking reaction is very important to understand and improve the in\|situ application of the gels technology.This paper reviewed several research methods on the mechanism and kinetics of the crosslinking reaction between HPAM and chromium (Ⅲ),such as Uv\|visible spectroscopy,atomic force microspectrocopy (AFM),laser light scattering method, and focused on the rheological measurements.
