摘要

本文重点讨论了热力作用在沉积盆地形成、构造变动、油气赋存等方面的地质效应和影响。研究认为:1）热力作用是盆地形成的重要动力和类型，论述了热力盆地形成机制和动力学过程;2）热力作用是富烃凹陷形成的必要条件，即国内外富烃凹陷一般均具有高-较高的地热背景;3）热力构造存在普遍，类型特殊，构造特征复杂。进而讨论了热力作用地质效应的判识及研究。

Abstract

This papermainly discusses the geological effects of thermodynam ic process on the formation of sedimentary basins，structural changes and hydrocarbon occurrence.Thermodynam ic process is an important dynamo type of basin-forming.It is one of the necessary conditions for the formation of a hydrocarbon kitchen，which in the world generally have high or relatively high geothermal backgrounds.Thermodynam ic structures are extensive in distribution，special in structural types，and complex in structural features.Identification methods of the geoˉlogical effects of thermodynam ic process are also discussed.
