The integrated well logging network platform is a large comprehensive system of well logging processing and interpretation that is the first in the world to totally adopt Java language development and support running in different systems. For the common features of interactive processing and interpretation modules with different languages, the paper proposes an advanced mode of cache based on proxy curve, and implements in Java language. The results of the large-scale integration testing and the interpretation of water-flooded layers in the Daqing oilfield show that, this proxy mode effectively solves the technical difficulty that the original cache function cannot be reused in the cross-platform integrating of different-language interactive processing software.
