| 1 | Surfactant induced reservoir wettability alteration:Recent theoretical and experimental advances in enhanced oil recovery显示文摘Reservoir wettability plays an important role in various oil recovery processes.The origin and evolution of reservoir wettability were critically reviewed to better understand the complexity of wettability due to interactions in crude oil-brine-rock system,with introduction of different wetting states and their influence on fluid distribution in pore spaces.The effect of wettability on oil recovery of waterflooding was then summarized from past and recent research to emphasize the importance of wettability in oil displacement by brine.The mechanism of wettability alteration by different surfactants in both carbonate and sandstone reservoirs was analyzed,concerning their distinct surface chemistry,and different interaction patterns of surfactants with components on rock surface.Other concerns such as the combined effect of wettability alteration and interfacial tension (IFT) reduction on the imbibition process was also taken into account.Generally,surfactant induced wettability alteration for enhanced oil recovery is still in the stage of laboratory investigation.The successful application of this technique relies on a comprehensive survey of target reservoir conditions,and could be expected especially in low permeability fractured reservoirs and forced imbibition process. | Wang Yefei XU Huaimin Yu Weizhao Bai Baojun Song Xinwang Zhang Jichao | 2011 | Petroleum Science2011，8，4： | 14 |
| 2 | Mathematical modeling of fluid flow, heat transfer and inclusion transport in a four strand tundish显示文摘Mathematical simulation was used for trouble-shooting and optimization. By the mathematical simulation, fluid flow and heat transfer of molten-steel in a four-strand tundish of a billet caster under different conditions (bare tundish and tundish with flow control device) were analyzed. The results showed that (1) the tundish with flow control device (FCD) has an important effect on the fluid pattern and temperature distribution; (2) the unsteady solving method was used to model the inclusion motions at different time periods, and it showed that the FCD is advantageous to separate the nonmetallic inclusions. According to the simulation results, the main problem existing in the industry production was found, and some helpful measurements were executed. Consequently, the large nonmetallic inclusions were separated, and the content of total oxygen was reduced. The quality of steel was greatly improved. | Yufeng Wang Guanghua Wen Ping Tang Mingmei Zhu Yuanqing Chen Weizhao Song | 2007 | Journal of University of Science and Technology Beijing2007，14，1： | 4 |
