The study of thermal simulation experiment on coal indicated that the Jurassic coal is aptto produce gas,the Triassic coal is apt to generate oil in a wide range of temperature,and mainly produce methane when it release gas and also it has high capacity of absorbing liquid bitumen.The Jurassic coal has lower oil production,which is about 1/6~1/8 amount of oil generated by Triassic coal,in a narrow range of temperature,releasing much CO 2,and it has higher efficiency of expelling oil,only as 1/10 quantity of absorbing liquid bitumen as the former.The primary cause of the difference in the potential oil generating ability of Mesozoic coal measure is the character and component of its organic macerals.It is difficult to form industrial oil-gas store because of the low potential oil generating ability and low maturity of Jurassic coal,and because of small scale and thin coal-beds of Triassic coal although its high potential oil generating ability.
