热力作用作为能量输出的一种形式,是地球上存在普遍、影响深远的主要地质动力和各种内动力地质作用的源头,是含煤、油、气、铀等多能源盆地发育、发展及动力学演化的主要源泉之一。富烃凹陷的勘探开发引起人们的重视,以烃源岩质量好、规模大、热演化程度较高、生烃量和聚集量大而备受关注。所有富烃凹陷均有较高的热背景和热演化过程,在其形成过程中,源于地壳或地幔深部、体现不同圈层物质交换的热力作用活动做出了不可代替,积极重要的贡献。地幔热物质的上拱控制着断陷盆地的发育和演化;热流物质通过深大断裂上涌至古湖泊,可造就古湖泊较高的有机物生产力;热力作用还能为盆地提供较高的热背景,加速盆地内有机质的成烃演化,加速油气生成速率。
As a form of energy output, thermal energy is the source of the universal and far-reaching major geodynamic forces and various internal-dynamic geologic effects on the earth. It is the development, development and power of multi-energy basins containing coal, oil, gas and uranium One of the main sources of evolution. The exploration and development of hydrocarbon-rich depressions have attracted people’s attention. They are of great concern because of their good source rocks, large scale, high degree of thermal evolution, large amount of hydrocarbon generation and accumulation. All hydrocarbon-rich depressions have high thermal background and thermal evolution. During the formation process, they originate from the deep crust or mantle and represent irreplaceable and positive contribution to the thermal activities that reflect the material exchange in different layers. The upper arch of mantle plume controls the development and evolution of faulted basins. The flow of heat flow material through the deep faults to the ancient lakes can result in higher productivity of organic matter in the ancient lakes. The thermal effects also provide a high thermal background for the basin , Accelerating the hydrocarbon evolution and evolution of organic matter in the basin and accelerating the rate of hydrocarbon generation.
