沉积盆地成岩作用的动力机制与时空分布研究若干问题及趋向

对成岩作用的物理—化学—生物过程的系统认识已经成为国际成岩作用研究的学术热点，而对沉积盆地尤其是化石能源盆地成岩作用重要性认识的加强，使得对成岩作用时空属性及其界定的精度要求愈来愈高。为此本文明确提出了在盆地动力学演化框架内，基于盆地沉积层序（岩石—矿物—化学体系配置）、埋藏、构造、流体格架分析，开展成岩作用时空分布研究的思路。进一步讨论了成岩作用的动力机制与时空分布研究若干问题和发展趋向，提出了应重视和开展地表温度变化对埋藏成岩作用，沉积结构及其矿物—化学体系对后期成岩改造的制约机理，断裂相、变形条带及其与碎屑岩储层裂缝或强压实改造关系，构造—流体活动耦合机制与流体—岩石相互作用效应等的研究建议。

Key Problems and Research Trend of Diagenetic Geodynamic Mechanism and Spatio-Temporal Distribution in Sedimentary Basins

A systematic study on the physical chemical biological processes of diagenesis has become an international academic hot spot. However, with the strengthening awareness about the importance of diagenesis in sedimentary basin, especially in fossil energy basin, it request more and more precise definition of the spatio temporal attributes. In view of basin geodynamics evolution, this paper propose an ideas for spatio temporal distribution research of diagenesis based on sedimentary sequence (rock mineral chemical system configuration), burial evolusion, structural strain pattern and fluid flow frameworks. We also discuss some key problems and research trend of diagenetic geodynamic mechanism and spatio temporal distribution, such as the effect of surface temperature change on burial diagenesis, later diagenetic modification controlled by sedimentary lithofacies and their mineral chemical system, fault facies, deformation bands and their influences on cracks or strong compaction of clastic reservoir, coupling mechanism between structure strain and fluid flow and the fluid rock interaction effects, etc.
