A METHOD FOR THE CALCULATION OF HYDROCARBON-GENERATION QUANTITY BY THE RELATIONAL DIAGRAMS OF HYDROCARBON CONVERSION RATE DURING KEROGEN PYROLYSIS

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.
