摘要
在提高原油采收率的过程中,涉及多种随时间和空间变化的界面现象,包括流体的传质、传热、动量传递,相的特征及毛细管力、浮力和黏滞力之间的相互作用.针对界面域内的演变、多样化和不稳定的流体流动形态的转化过程,在论述激活迁移滞留油的基础上,引进物理化学、非平衡态热力学、动力学、活力学、微观动力学的有关理论,提出活化集成涌现和活力观的概念与理论,阐述活化集成涌现过程主要包括的失稳分解和成核生长机制及其过程;在论述系统演化与质能转换的关系中,突破物理学与化学的界限,阐明状态参数火用的含义,指出在界面域内的激活迁移滞留油的多势场中,火用效应、熵效应、场效应是共存的,其竞争与协同的交叉作用的方式、数量与质量的差异铸就出多变的构形,这是非平衡动态系统演化的本质内涵(内动力)所在.它将提高原油采收率的研究推进到一个新的层面,同时也为探索客观世界(尤其是具有生理活动)的复杂现象提供新的途径和方法,具有理论创新和实践应用的双重意义.
In the process of enhancing oil recovery,a variety of interface phenomena is involved with the change of time and space,including mass transfer,heat transfer and momentum transfer of fluid,phase characteristics and the interaction of capillary force,buoyancy and viscous forces. Based on the discussion of activating and removing irreducible resident oil,the theories of physical chemistry,non-equilibrium thermodynamics,dynamics,energy science and micro-dynamics were introduced for research of evolution,diversity and transformation process of fluid flow of the instable patterns in the interface domain. At the same time,the concept and theory of activated-integrated emergence and energy view were proposed for the first time. The process of activated-integrated emergence,including the mechanism and process of spinodal decomposition and nucleation-growth,was expounded. In the discussion of the relationship of system evolution and mass-energy conversion,this theory broke through the boundaries of physics and chemistry to clarify the meaning of state parameters-exergy,and pointed out that exergy effect,entropy effect and field effect were coexistent in the mutil-potential field of the activation integrated emergence in the interface domain. The differences of competition and synergistic function of those effects in manner,quantity and quality modeled the extraordinary and varied configuration,which is the essence of non-equilibrium dynamic system evolution connotation (inner power). It will not only push the work of oil recovery deep into a new dimension,but also provide a new way to explore complex phenomena of the objective world (especially those with physical activity). Therefore,it has a double significance of theoretical innovation and practical application.
