石油地质动力学的内涵与展望

CHARACTERISTICS AND PROSPECT FOR DYNAMIC STUDY OF PETROLEUM GEOLOGY

石油地质动力学的本质特征是在现代地质理论基础之上，应用数学、物理学、化学和生物学等理论和方法，借助先进的计算机和实验测试、模拟技术，定量地研究沉积盆地油气生、运、储、聚和保的机制、速率和过程。石油地质动力学研究的核心问题有两个：一是沉降作用，二是流体压力系统形成与演化，成藏动力是石油地质动力学研究的纽带。石油地质动力学现行研究方法可分为盆地动力学、石油地质动力学（狭义）和地质作用过程动力学，重点介绍了成岩过程动力学的研究方法及当今研究的前沿领域，即热流体与有机／无机成岩作用。最后，笔者展望了石油地质动力学研究在我国那些具有多旋回叠合性含油气盆地的发展和应用前景。

In developing of petroleum industry,petroleum geology is proceeding in dy-namic studies,In this paper,firstly,the authors suggest that the essential characteristicsof petroleum geology be the applications of mathematics,physics,chemistry and biologywith modern computers,testing and modeling techniques to quantatitively investigate themechanism,rate and process of hydrocarbon generation,migration,accumulation,reser-vation and reservoir evaluation in sedimentary basins.But the key in petroleum studies issubsidence which is related to burial history,tectonic development and pore fluid pressuresystem formation and evaluation concerning hydrocarbon reservoiring,Secondly,specialmethodology for three subareas of petroleum dynamic study is introduced here:(1)basindynamics,(2)dynamics of petroleum geology(in restricted sence),and(3)dynamics ofgeological processes. Then the diagenetic dynamics is discussed to indicate the thermal flu-id movements causing organic/inorganic diagenesis,Finally,some relationships concern-ing our view on application and significance of dynamic studies of petroleum geology inChna are also discussed.
