Abstract
We have been exploring oil and gas in Sichuan for a long time, and have discovered a great number of oil and gas fields in Sichuan, most of which are structural and formed of Carbonates. Now we are facing a problem-what to do after most structural traps have been discovered. In addition to structural traps, we must explore stratigraphic taps and diagenetic traps. As a matter of fact, some diagenetic traps have been discoverde already. Besides, in present paper the mechanism, classification and characteristics of diagenetic traps are discussed, and latest information about diagenetic traps is intrlduced. Finally, we have discussed the problem how to explore carbonate diagenetic traps in Sichuan.
