Abstract:

shuigou reef com plex, studied their origin and the role in the process of
their occurence, in particular, their relation to the dolomitization in the
burial diagenetic stage. The existence of neptunian dikes is of great signi-
ficance in the migration and accumulation of oil and gas，and other dia-
genetic fluids.

Key words: Reef complex, Neptunian dike, Upper Permian, Dolomitization in the burial diagenetic stage
