主　　题：Shaly sand Conduction model Logging Clay-bound water Micro-pore 

摘      要：There are so many shaly sand conduction models, and most of them are only used in some local area, and have their limitations. So far, there is no theoretical model that can be used commonly and efficiently .In this paper, based on some existing models, and combining with the knowledge of the researched area, we designed out a new conduction model. The total conductivity of the rock is the combining result from free water in inter granular porous, micro pore water and the clay bound water. It can well describe many electric conduction characteristics of shaly sand. In order to make it useable in practice, we also provide some methods for interpreting the pore components with comprehensive logging data.
