| 摘 要： | 砂岩压实作用研究主要包括压实作用机制、影响因素和响应特征三方面内容，重点阐述了砂岩压实作用模型与数值模拟研究、压实作用物理模拟与数值模拟融合研究两方面的新进展，结果表明:1）压实作用模型包括机械压实作用和化学压实作用模型，机械压实作用模型重点介绍了石英砂岩的粒间体积-深度曲线；而化学压实作用模型是与压溶作用相关的溶解作用和胶结作用，着重介绍了压溶成因的石英胶结作用。2）压实作用物理模拟与数值模拟的融合研究，主要是在压实作用机理认识基础上，通过压实模拟实验，建立基于实验数据的压实作用模型，进而开展数值模拟研究。最后指出压实作用研究趋势将朝着砂岩组分更加复杂的压实作用模型、压实作用与流体流动耦合、垂向-侧向多动力学机制、砂岩-泥岩协同机制、构造-沉积-成岩"三相"耦合的压实作用数值模拟等方面发展。

| Abstract: | This study of the sandstone compaction mainly included three aspects:the compaction mechanism, the controlling factors and the response characteristics. The focus is on two aspects of recent research progress:compaction modeling and numerical simulation, and the integration of experimental compaction models with numerical simulation. The results show that:(1)compaction models included mechanical and chemical compaction models. Mechanical compaction models focus on the intergranular volume-depth relationship curve for quartzose sandstone; chemical compaction models is the dissolution and precipitation related to pressure solution, and the quartz cementation causedby pressure solution is emphasized. (2)The coupling of experimental compaction modeling and numerical simulation is mainly based on current knowledge of compaction mechanisms. Numerical simulation models are based on experimental data. It is suggested that compaction research might be directed towards the development of a compaction model of sandstone of complex composition, the interaction of compaction and fluid flow, vertical/lateral multi -dynamic mechanisms, and sandstone-mudstone cooperative mechanisms, as well as numerical simulation studies of the compaction effect of tectonism-sedimentation-diagenesis interaction. |
