Based on an analysis of the mainstream software and in combination with the characteristics of well logging data in Sichuan and Chongqing areas, the GeoReveal software is thus developed for calculating parameters of complex reservoirs. This software has been applied to the processing of logging data and the integration of optimization processing modules for the clastic reservoirs with complex lithologies of the Xujiahe Formation, reef-bank reservoirs of the Longgang Formation, and carbonate reservoirs with complex lithologies in the central Sichuan Basin. The results show that the GeoReveal software has high expandability and can replace the previous reservoir parameter processing softwares.
