摘　　要：成岩体是指在埋藏成岩作用过程中形成的、内部具有成因联系的、不同规模尺度的地质体。从多尺度成岩体研究入手,阐明成岩体中控制流体-岩石相互作用的热力学和动力学条件,揭示流体-岩石相互作用机制,提出以成岩相为核心的多尺度成岩体划分方案,进而归纳总结了成岩体系域、成岩体系、成岩相和成岩亚相不同尺度成岩体的流体-岩石相互作用研究新进展。从单相/多相流体和单矿物/多矿物相互作用角度,将流体-岩石定量模拟划分为长石-流体相互作用定量模拟、石英-流体相互作用定量模拟、多矿物-流体相互作用定量模拟和多相多组分流体-岩石相互作用定量模拟。今后拟重点开展的研究有:层序地层格架/沉积相带框架下不同成岩体内的流体-岩石相互作用研究,陆相断陷盆地内与深大断裂、断裂输导有关的流体-岩石相互作用研究,煤系地层背景下致密储层中有机酸流体-岩石相互作用研究,咸化湖盆储集层中流体-岩石相互作用研究,以及中、新生界碎屑岩风化壳内流体-岩石相互作用研究等。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 andsingle 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 fluidrock 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 coalbearing strata,the reservoir in saline lacustrine basin,and the clastic weathering crust in Mesozoic-Cenozoic.
