深部热流体穿层对盆地热-应力状态的影响

On the based of analyzing the egulation of migration of deep hot luidspene trating upward, the hot exchanging of deep hot fluids with their wall rocks has been researched in the migration process of fluids in Yinggehai basin. Furthermore, it is quantificationally analyzed that the deep hot fluids penetrating upward influence thermal and stress field in the basin. The stress field and hot exchanging resulted from the thermal difference have been quantificationally.simulated, then the deep hot fluids penetrating upward influencing the distribution of shallow.thermal situation and stress fields have been proposed. The research combines multidiscipline,.combining fluid dynamics and thermal dynamics, combining physical analysis with numerical simulation. The innovative researches in the study are quantificational analysis of evolution of thermal and stress in the basin and the quantificational simulation of deep hot fluid migration.keywords: hot fluid migration, thermal stress field, temperature field, fluid inclusion

以莺歌海盆地和辽河盆地为例，在分析盆地深部热流体向上穿层运移规律及其运移过程中与围岩所进行的热交换的基础上，对热差异所导致的应力场、热交换进行定量模拟计算，从而提出热流体对于浅层的热-应力分布状态的定量影响。本研究利用流体动力学和热动力学手危教秩攘魈逶谂璧囟ρе械淖饔茫耘璧氐亩ρЯ炕芯烤哂锌匦缘囊庖濉
