摘要
通过对地球和岩石圈结构以及大地热流的产生和传导等的分析,探讨了热流体持续活动的条件;从镜质体反射率、流体包裹体、自生矿物的演化、孢子颜色、磷灰石裂变径迹等方面分析了热流体活动的主要示踪标志;从有机质演化、储层物性和油气运移等方面分析了热流体活动对油气成藏的影响。认为热流体活动可以促进有机质的热演化,增加油气运移的效率,并为油气运移提供动力和通道,对深部储层的物性具有改善的作用,但对浅部储层的物性具有负面影响。
On the basis of analyzing the structure of the earth and rock sphere and the generation and transmission of geothermal heat flow, the authors of this paper firstly probe the condition of thermal fluid sustainable movement. And then, according to the relationship among lithology, unconformity, fault and thermal fluid movement, thermal fluid movement is classified into three types, including lateral migration, vertical migration and composite migration. And trace markers of the thermal fluid movement including vitrinite reflectance, fluid inclusion, evolution of authegenic minerals, color of sporopollen, apatite fission track and so on are analyzed. And lastly, the influence of thermal fluid movement on evolution of organic matter, hydrocarbon migration and reservoirs is discussed. It is pointed out that thermal fluid movement can accelerate hydrocarbon generation, improve the efficiency of hydrocarbon immigration, provide the dynamic and pathway for hydrocarbon migration, and improve the physical properties of reservoirs in deep zone and worsen the physical properties of reservoirs in shallow zone usually.
