Hydrocarbon Generation Kinetics of Source Rocks under Different Pyrolysis Conditions in Bozhong Area
摘要
Abstract
To study oil and gas generation activation energy of different samples under different pyrolysis experiments,open system anhydrous pyrolysis and confined system hydrous pyrolysis are performed on lacustrine shale source rock,raw rock and kerogen samples from Bozhong area.Source rock samples are from different sags and different intervals,and have different organic matter abundance,kerogen type and maturity.The results shows that kerogen type and maturity have important influence on oil generation activation energy,and mean oil generation activation energy increases as organic matter type becomes poorer and maturity is higher.Different sags,source rock intervals and sample type have no obvious influence on mean oil generation activation energy,but sample type influences the distribution.Hydrocarbon generation activation energy distribution of raw rocks is more concentrated than kerogen.Gas generation activation energy of mature source rocks is 11-17 kJ/mol higher than that of low mature source rocks.Compared with open system anhydrous pyrolysis,confined system hydrous pyrolysis has more concentrated activation energy distribution including primary and secondary cracking.Confined system hydrous pyrolysis of low mature source rock raw samples and mature source rock kerogen samples for oil and gas generation kinetics respectively are recommended.关键词
