Aimed at the problem of no an effective method to evaluate the generation amount of low-mature gas quantitatively, this paper deduces, based on the formation mechanism of low temperature thermal thermogenesis of low mature gas, that the chemical kinetics theory, which has been applied widely and successfully in evaluating generation amount of normal thermal thermogeneicsis natural gas, remains to be an effective meothod of evaluating the low-mature gas generation amount of low-mature gaseous. On this foundation, the chemical kinetics models of representative kerogen samples of kerogen are constructed and calibrated, and in accompany with the kineticals models of resine and asphatene, which may be the precursor of low mature gas partly, they constitutes the evaluation meothod of low mature gas. It is the few minor compoenents with of low activation energy that results in the generation of low mature gas. The initial application indicates that the total generation amount of low mature gas is about 41 992×108m3 in north Songliao basin. In case of 1% of migration and accumulation coefficient, the resource amount of low mature gas is about 420×108m3，much lower than that of the normal thermal thermogenesisic natural gas. This suggests that it is workable to evaluate the generation amount of low mature gas using the chemical kinetic models and it can be also to popularize to other basins rich in low mature gas.
