摘要
地球内部不同层圈相互作用过程中的物质循环和能量传递对浅层盆地内部多种类型资源的形成及富集具有显著影响。深部地质作用过程与浅部资源效应这一核心科学问题备受关注,其中在深部流体/熔体物质传输影响下的有机—无机相互作用及资源效应是关键所在。梳理了地球多层圈有机—无机相互作用对盆内多种资源的影响机理。在深部流体/熔体活动背景下,有机—无机相互作用主要通过形成利于富有机质烃源岩发育的沉积环境、提供促进生烃的物质能量、产生改造储层性质的流体环境和影响油气组分的聚集效果的方式控制油气资源的形成和聚集;深部流体携带地球深部的气体组分(CH_(4)、H_(2)、CO_(2)等)和热能进入盆地促使了天然氢气和地热资源潜力的形成;深部物质为铀矿提供铀源,富铀流体在生物作用和含烃流体作用下形成砂岩型铀矿;深部流体活动对煤矿资源的形成和变质也产生了较大影响。未来针对地球多层圈有机—无机相互作用的研究应当突破盆地限制,在地球系统的背景下围绕层圈物质和能量传输、盆内与盆外一体化展开。重点对非生物烷烃气成因、工业聚集和天然富(含)氢气藏的成因、富集、潜在勘探区评价、地质储存开展深入研究,助力推进中国能源转型和绿色发展。
Material circulation and energy transfer during the interaction of the Earth's inner spheres have a significant impact on the formation and evolution of many types of resources in the shallow of the Earth's crust.The core scientific issue of deep geological processes and shallow resource effects has attracted much attention.It is crucial to investigate the resource effects of organic-inorganic interactions on the Earth in the context of deep fluid activity.In this paper,the response mechanisms of Earth's multi-spheres organic-inorganic interactions on various types of resources were sorted out.Under the background of deep fluid activity,organic-inorganic interactions control the formation and aggregation of hydrocarbon resources mainly through the following ways:(1)forming a depositional environment conducive to the development of organic-rich hydrocarbon source rocks;(2)providing material and energy to promote hydrocarbon production;(3)generating fluid environments that modify the nature of the reservoirs;and(4)influencing the effect of the accumulation of hydrocarbon components.Inorganic gases(H_(2),CO_(2),etc.)and thermal energy from the deep Earth carried into the basin by deep fluids effectively increase the potential of natural hydrogen and geothermal resources.Deep material provides a source of uranium,and uranium-rich fluids to form sandstone-type uranium ores by biological and hydrocarbon-bearing fluids.The formation and metamorphism of coal resources are also affected by deep fluid activities.Research on organic-inorganic interactions in the Earth's multi-spheres should break through basin constraints and focus on two aspects(material and energy,intra-and extra-basin)to explore in the context of the Earth system.The research should concentrate on the genesis of abiotic alkane gas,industrial accumulation,and the genesis,enrichment,evaluation of potential exploration areas,and geologic storage of natural hydrogen-rich gas reservoirs,to help promote China's energy transition and green development.
