2) residual oil
Influence of viscoelasticity and interfacial tension of non-alkali binary compound solution on recovery efficiency of residual oil after water flooding;
Effect of polymer/amphoteric surfactant compound system on residual oil after water flooding in ultralow interfacial tension;
Enhanced residual oil recovery by using polymer/betaine surfactant system after water flooding;
3) residual oil pools
Identifying residual oil pools and reconstructing hydrocarbon charge history by a quantitative fluorescence techniques along Panyu low uplift-north slope in Baiyun sag;
4) residual oil film
Efffect of viscoelastisity of HPAM solution on residual oil film;
In connection with residual oil film of different forms after water flooding on the oleophilic rock and the viscoelasticity character of the polymer solution,the Upper-Convected Maxwell constructive equation of viscoelastic fluids was choosed,the model was analysized numerically by using computation fluid software-Polyflow.
5) residual ink
What Caused the poor bleachability of DIP fines? the two factors coming from external contamination were: residual ink and transition metals in pulp,specifically iron.
Through analyzing particle number and particle size of residual ink as well as brightness, the effects of solvent pretreatment on deinking process for mixed office paper were evaluated, meanwhile, deinking process was optimized.
