Title : Gas generation mechanism of interaction between organic matter and water in high evolution stage


In this paper, a comparative simulation experiment of bitumen, crude oil and kerogen samples under water and no water conditions was conducted to study the mechanism of the interaction between highly evolved organic matter and water. The results show that. The participation of water improves the yield of natural gas from the pyrolysis of high evolution residual organic matter. The participation of water delays the cracking of ethane and propane, resulting in low drying coefficient of natural gas and delayed reversal of carbon isotope, which inhibits the generation of natural gas at low temperature. The participation of water can provide hydrogen source, promote the further cracking of high evolution residual organic matter macromolecules at high temperature stage, and promote the generation of natural gas.
