Abstract
”In order to reduce the water production and improve the oil recovery of mature reservoir, various conformance control technologies have been extensively developed. Preformed particle gel (PPG), a cost-effective plugging agent, has been successfully applied to block the high permeability zone and thus to displace the water to up-swept zone.
A common PPG based on polyacrylamide hydrogel have been wildly used. Identifying the parameters that affect gelation performance and understand how these parameters affect the performance is very useful to predict and manipulate the gelation time and to control the performance of gels.
The objective of this research is to optimize the concentration of three persulfate initiator systems and to study the effect of some factors (water content, initiator concentration, temperature and pH value) on the gel performance (gelation time, gel strength, swelling ratio and exothermicity). The four types of initiators test during this research are ammonium persulfate (APS), ammonium persulfate (APS)/potassium persulfate (KPS), ammonium persulfate (APS) / sodium thiosulfate (STS) and ammonium persulfate (APS) / sodium metabisulfite (SMS) initiator system.
Experimental results showed that different initiator system will be selected according to the different synthetic conditions. All the factors which tested in this research can sensitively affect the gelation time. The gel strength is scarcely influenced by initiator concentration and temperature and greatly affected by water content and pH value”--Abstract, page iii.
