沉积盆地热演化波动问题初探

THERMAL UNDALATORY EVOLUTION IN SEDIMENTARY BASINS

本文应用波动分析的观点,探讨沉积盆地温度变化的波动性及盆地演化过程中温度和热流的波动变化,提出沉积盆地热流变化的波动模式,并以此研究了单井的热流变化情况,从而为沉积盆地热史研究提供了一种可能的新方法。

The geothermal regime of sedimentary basins is a concrete manifestation of structural movement and it evolves with the evolution of basins.Due to the undulatory characteristics of the structural movement,the geothermal evolution of a sedimentary basin is also Based on the undulation analysis,the undulatory characteristics of the geothermal variation during the evolution of sedimentary basins are discussed.Moreover,the process of undulatory evolution of heat flow is studied and the undulation model of heat flow of sedimentary basins has been established.Based on this model,a single well heat flow variation has been carried out,which may be thought to be a new method for the study of the geothermal history of sedimentary basin.
