摘要
阐述了由达西定律反映的驱油过程速率、动力与阻力间的动力学基本关系,分析得到热驱过程耦合现象的本质是,通过加热改善了与驱动有关的传递过程的动力与阻力特性,使得采油速率及采收率同时得到提高。以势场为载体,根据驱油过程"流"与"力"的相互关系,将驱油过程多场耦合的多层次描述慨括为动力势场与阻力势场的耦合、动力势场间的耦合及阻力势场间的耦合。在此基础上,结合渗流力学的基本研究方法,给出多场耦合分析方法的一般步骤。最后以热水驱替过程为例作多场耦合分析,可从新的角度清晰、深入地描述此类过程。
The basic dynamics relation between rate,driving and resistance of oil driving process from Darcy Law is expounded.Then the nature of synergy phenomenon of thermal driving process is analyzed,i.e.heating improves the driving and resistance feature of the related transfer process and thus increases the rate of oil production and recovery ratio simultaneously.Using potential field as the study carrier,according to the relation of the flow and force,the levels description of multi-field synergy are summarized as between driving fields and resistance fields,among the driving fields and among the resistance fields.Based on that,considering the fundamental study method of seeping dynamics,the general steps of multi-field synergy analysis are provided.In the end the hot water driving process is taken as the example to make multi-field synergy analysis and to describe this kind of process clearly and deeply from the new point.
