摘要
从动力学原理出发，以热解法为手段，测定了准噶尔盆地部分地区侏罗系烃源岩的动力学参数。研究表明，活化能的大小与有机质类型之间呈现出规律性的变化；活化能的大小与烃源岩的岩性和沉积年代有关；对准噶尔盆地侏罗系而言，八道湾组的烃源岩生烃量贡献较大。
Based on the dynamic theory,dynamic parameters of Jurassic source rock in local Junggar basin were measured by means of pyrolysis process.It is suggested that activation energy exhibits a regular relation with type of organic matters,i.e.the more preferential the organic type,the higher the activation energy necessary in the major periods of hydrocarbon generation,the narrower the distribution of activation energy,the higher the proportion of hydrogen index in the major stage of hydrocarbon generation.Moreover,the activation energy and its distribution are related with the lithology and sedimentary dating of source rock.In the Jurassic, Junggar basin,Badaowan formation source rock contributes more to hydrocarbon potential.
