原油裂解成气热模拟实验研究进展

Advances in pyrolysis on crude oil for cracking gas

原油裂解气的形成条件是目前油气生成过程研究的热点。热模拟实验是探索油气形成机制、重现油气生成过程的重要手段之一。文中介绍了原油裂解成气过程中的影响因素,重点阐述了原油裂解气和干酪根裂解气的判识依据,指出了原油裂解成气热模拟实验存在的不足和需要深化的区域。

The condition of oil cracking to gas is a hotspot of the research in the process of hydrocarbon generation.At present,pyrolysis is one of the important methods in probing into the hydrocarbon-forming mechanism.In this article,the author describes the geological factors affecting the oil cracking to gas(temperature,pressure,types of organic matter and mineral matter),emphasizes the index for distinguishing cracking gas from oil or kerogen(composition of natural gas,light hydrocarbon,carbon isotope from CH4 to C3H8,composition of nonhydrocarbon),and points out the shortage in the pyrolysis on the crude oil for cracking gas.
