| 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 | 软岩渗流-化学-损伤软化过程中能量耗散机制显示文摘红层软岩具有遇水软化特性,在降雨条件下渗流、化学、力学损伤等多效应综合作用造成工程地质灾害,是岩土工程界广泛关注的热点和难点问题之一。基于能量耗散原理,研究了软岩软化过程中的渗流、化学、损伤效应,提取了主要的渗流、化学、损伤能量变量,讨论了渗流-化学-损伤效应对软岩软化过程的作用以及能量耗散的机制,结合软岩三轴试验分析了能量耗散过程。结果表明:在渗流-化学-损伤效应共同作用下,水在软岩中形成渗流,渗流的作用加速了软化进程;软岩与渗流之间的化学作用加速了裂隙-孔隙损伤的发展;软岩裂隙-孔隙损伤的发展反过来促进了渗流及化学的作用。从能量角度来看,软岩软化后可承受的极限应变能量减少,渗流提供了能量同时也通过化学效应消耗了软岩自身的能量,降低了强度并引发损伤,因此,软岩软化的过程是一个能量耗散的过程。在此过程中,渗流、化学、力学损伤等能量的涨落及耗散、物质交换、非线性正反馈作用,使得软岩经历从平衡态到非平衡态相变,最终软化破坏形成了耗散结构。 | 周翠英 苏定立 刘镇 | 2019 | 工程地质学报2019，27，3： | 14 |
| 3 | MAPE增强木塑复合材料相容性的耗散粒子动力学模拟显示文摘采用耗散粒子动力学(DPD)方法,模拟比较了添加/不加相容剂MAPE对木质纤维/聚乙烯混合系统相容性的影响,并对这一模拟进行了实验的验证。模拟结果表明:相容剂MAPE在木质纤维/聚乙烯的混合界面处起到了桥梁的作用,能够有效地将木质纤维、聚乙烯联接起来,增加混合系统的相容性。实验结果也表明:添加了MAPE后复合材料断面拉丝较多且长,复合材料间结合紧密。实验与模拟所得结果很好地吻合。 | 吴远艳 李楠 樊永明 高建民 刘勇 | 2014 | 塑料2014，43，5： | 3 |
| 4 | Numerical simulation of pore-scale flow in chemical flooding process显示文摘Chemical flooding is one of the effective technologies to increase oil recovery of petroleum reservoirs after water flooding.Above the scale of representative elementary volume(REV), phenomenological modeling and numerical simulations of chemical flooding have been reported in literatures,but the studies alike are rarely conducted at the pore-scale,at which the effects of physicochemical hydrodynamics are hardly resolved either by experimental observations or by traditional continuum-based simulations.In... | Xiaobo Li,~(1,a) Shuhong Wu,~1 Jie Song,~1 Hua Li,~1 and Shuping Wang~2 1.Research Institute of Petroleum Exploration & Development of Petrochina,Beijing 100083,China 2)Petroleum Exploration & Production Research Institute of Sinopec,Beijing 100083,China | 2011 | Theoretical & Applied Mechanics Letters2011，1，2： | 3 |
