本文所介绍的生烃量计算方法,同时考虑了有机质类型、丰度、成熟度(受热程度)和粘土矿物组成特征4个因素。具体方法是把干酪根与伊利石、蒙脱石、高岭石3种粘土矿物按一定比例混合后,在CDS820GS分析系统上进行多步热解,记录不同实验条件下的实验结果,分别研制"干酪根热解烃转化率关系图版"及其他有关图版,再结合其他地质和地球化学资料计算生烃量。

The calculation method of hydrocarbon-generation quantity introduced in this paper has given consideration simultaneotisly to four factors such as the type,abundance and maturity(degree of heat subjected)of organic matter and the compositional characteristics of clay mineral.The concrete method is to perform multiple pyrolyses using a CDS 820 GS analytical system after mixing kerogen with three clay mineral as illite,montmorilonite and kaolinite in certain proportion,record the experimental results under different experimental conditions,and develop"the relational diagrams of hydrocarbon conversion rate during kerogen pyrolysis"aiid other relatioiial diagrams respectively,And then hydrocarbon-generation quantity can be calculated by combining these diagrams with other geological and geochemial data.
