原始语种摘要: ABSTRACT(#br)Preformed particle gel (PPG) is a particled superabsorbent crosslinking polymer that has been successfully applied to control conformance. The aim of this study was to develop and evaluate the properties of PPGs based on crosslinked partially hydrolyzed polyacrylamide with polyethyleneimine (PEI). The study was conducted into two steps: (1) the preparation of standard hydrogels, which were dried and grounded to obtain preformed particles, using the Sydansk strength code and rheology for evaluation and (2) the determination of the swelling degree from the PPGs under typical reservoir conditions (temperature of 90 °C and salinity int about 29,940 mg/L of total dissolved solids). Sydansk coding is a method that provides semiquantitative measures, and it is expressed in an...
