主 题:Scale inhibitor Formation damage Scaling index Static test Dynamic test SEM test
摘 要:Scale formation due to the mixing of injection water with formation water causes formation damage and reduction in petroleum *** using scale inhibitors,scale formation/scaling could be *** this work,static experiments were performed with rapid controlled precipitation tests,which were undertaken using three different scale inhibitors namely Falat scale inhibitor,Scahib 760 scale inhibitor and Scahib 780 scale *** show that parameters such as temperature and pH have significant effects on scale inhibitor *** this study,at pH of 7.8e9 it was found that an increase in pH can lead to a decrease in SI *** addition,acquired data shows that Falat scale inhibitor is more efficient at 45C but scale inhibitors(Scahib 760,780)have better efficiencies at 25*** tests were performed to find structure deformation and morphology of precipitation crystals,which indicated that scale inhibitor can have various effects on crystal s ***,dynamic tests were performed with coreflood equipment that indicated higher recovery by using the scale *** dynamic tests results show that the recovery factor in the presence of Scahib 760 scale inhibitor is about 58%and breakthrough time is 2099(sec).In the absence of scale inhibitor,the recovery factor is about 52%and breakthrough time is 2720(sec).
