As an important bioprecursor of hydrocarbons in source rocks, Seaweeds (showing as macro-algae) have been attracting more and more attention from petroleum geologists. Laminaria, as a typical species of Phaeophyta, was used in the thermal simulation experiments in this study. FT-IR, SEM, diffuse reflectance spectrum, reflectivity and microscopic observation were employed to study the thermal evolution, potential of hydrocarbon generation and changes in pore structure of Laminaria. It is discovered that Laminaria has significant potential of hydrocarbon generation even under relatively high maturity of organic matter. The change in pore structure of Laminaria in geological environment is important for the preservation and expulsion of gaseous hydrocarbons. The results will highlight the exploration and evaluation of marine petroleum system.
