Abstract:
Diagenetic body is a geological body formed in the process of burial diagenesis, which has genetic relationship and different scales. Starting from the study of multiscale diagenetic body, the thermodynamic and kinetic conditions for controlling fluid-rock interaction in the diagenetic body were elucidated, and the mechanism of fluid-rock interaction was revealed. Classification scheme of diagenetic body for diagenetic facies as the core, including diagenetic system tract scale, diagenetic system scale, diagenetic facies scale, and diagenetic sub-facies scale, was proposed. The new progress of the above four diagenetic bodies in different scales was summarized. From the point of view of the interaction between single phase/multiphase fluid and single mineral/multi-mineral, the quantitative simulation technology of fluid-rock interaction can be classified as fluid-feldspar interaction, fluid-quartz interaction, fluid-multi-mineral interaction and multiphase multicomponent-fluid interaction quantitative simulations. The study on fluid-rock interaction is suitable for focusing on research issues, such as the geo-body under a stratigraphic sequence framework/sedimentary facies belt framework, the continental rift basin related to deep fault and fault accommodation, the organic acid from tight reservoir in coal-bearing strata, the reservoir in saline lacustrine basin, and the clastic weathering crust in Mesozoic-Cenozoic
