Abstract

By means of thermal simulating experiment in the open system, this article focused on the hydrocarbon\|generating characteristics of Trias source rock from well Ha 2 in Tarim basin, it also combined with the alteration of maceral and maturation to discuss the characteristics of generating hydrocarbon. The result of experiment indicate that the accumulative yield is only 1.04 mL/g when the heating temperature is under 400℃( value of R O is below 0.8%), it only reach to 8.2% of the total gas yield. When the heating temperature reaches 600℃, the accumulative yield is 9.23 mL/g (about 72.7%of the total gas yield). The peak yield of hydrocarbon is between the heating temperature 500℃ and 600℃ (the value of R O is from 1.24%  to 1.78%), the periodical yield in this evolution period is 6.23 mL/g (about 50% of the total gas yield). Although the humin component still could generate hydrocarbon when the heating temperature reaches 700℃, it has already been entered into the period of dry gas. The period of large quantity of generation has finished.
