hydrocarbons in condensates

five types of condensates inSichuan basin are classified.1.Mature condensates from terrestrial materials.2.supermature condensates predominatly from terrestrial materials.3.Mature condensates from lacustrine sapropelites.4.Supermature condensates from marine sapropelites.5.Mixed supermature condensates from different origion.Other geochemical data confirm that the condensate classification on the characters of light hydrocarbons is reliable.
