摘　　要：油气系统动力学作为油气系统概念的进一步外延,着重强调油气系统的动态性、反馈性特征,要求着重分析油气系统的物质流、能量流、信息流及其控制和反馈控制过程。页岩油气藏作为一种新型非常规油气藏,主要是由于排烃浮力无法克服致密页岩的低孔隙度,导致油气在原本生成油气的页岩中保存。页岩油气藏是研究勘探领域的新热点,而从油气系统动力学视角分析页岩油气藏的研究相对较少,这对页岩油气藏的研究工作来说少了一种有力的手段。从油气系统动力学角度分析了页岩油气藏的物质流、能量流和信息流过程,认为页岩油气藏的物质流主要包括生烃物质流和排烃物质流,能量流主要包括生烃能量流和排烃能量流,信息流主要包括油气对页岩的控制和页岩对油气的反馈控制。松辽盆地古龙页岩油的研究开发实例证明用油气系统动力学探讨页岩油气藏是可行的。Oil and gas system dynamics,as an extension of the concept of oil and gas systems,emphasizes the dynamic and feedback characteristics of oil and gas systems.It requires a detailed analysis of material flow,energy flow,information flow,as well as their control and feedback control processes.Shale oil and gas reservoirs,as a new type of unconventional oil and gas reservoir,primarily exist because hydrocarbon buoyancy cannot overcome the low porosity of tight shale,thus preserving hydrocarbons in the shale where they were generated.Shale oil and gas reservoirs have become a new research hotspot in exploration,yet there has been relatively little research analyzing shale oil and gas reservoirs from the perspective of oil and gas system dynamics.This represents a significant gap in effective research methods for shale oil and gas reservoirs.This study analyzes the material flow,energy flow,and information flow processes of shale oil and gas reservoirs from the perspective of oil and gas system dynamics.It suggests that material flow in shale oil and gas reservoirs mainly consists of hydrocarbon generation and expulsion material flows,energy flow includes hydrocarbon generation and expulsion energy flows,and information flow involves the control of hydrocarbons by shale and the feedback control of shale by hydrocarbons.Research and development examples of the Gulong shale oil in the Songliao Basin demonstrate that applying oil and gas system dynamics to the study of shale oil and gas reservoirs is feasible.
