Study of pyrolysis kinetics of asphaltenes in Silurian oilsands in the Tarim basin

It is a special petroleum geological phenomenon that Silurian oilsands are extensively distributed in the central and northeast Tarim basin. Some geoc hemical studies of the oilsands have been carried out, but there is still g reat controversy over the hydrocarbon-regenerating potential of oilsands an d the possibility of Silurian oilsands as hydrocarbon source rocks. In this study, the kinetics of asphaltenes pyrolysis was directly used to simulate the potential of Silurian oilsands for regenerating hydrocarbons. Accordin g to the experimental results, combined with other related organic geochemi cal analysis, it is considered that Silurian oilsands in the Tarim basin ha ve a high hydrocarbon-regenerating potential and are latent hydrocarbon sou rce rocks.
