有机油气形成的影响因素——模拟实验的研究进展

doi:10.11743/ogg20040302

Abstract

Abstract:

Petroleum resources in the earth have been formed mainly through pyrolysis of organic matters in deeper part of the earth.In recent years, many understandings of the mechanism have been achieved through simulating experiments.Types of organic matters,temperature,pressure,catalysis and aqueous medium all have influences on the properties of hydrocarbons generated.Increase of pressure can impede or delay thermal evolution and pyrolysis of organic maters;water is the source of hydrogen and oxygen for pyrolysis reaction;and catalysis can not only change components of reaction products, but also influence the reaction mechanism.Kinetics is also an important factor influencing pyrolysis of organic matters,which provides a new way to identify various source rocks.In the future,attentions should be paid to the study of characteristics of pyrolysis of organic matters under higher pressure condition,and the development and application of field experimental apparatus.

Key words: organic matter, pyrolysis, hydrocarbon generation, simulating experiment
