The Application of Surfer Software in the Fracture and Bedding Identification

摘要

Fractures and bedding planes identification are the foundation of the fracture reservoir exploration.The paper researches the problem of remapping for the electric imaging logging data with Surfer software,which is based on the fractures and bedding planes identification of predecessors.On the basis of the research,we draw the higher electrical conductivity zones by defining the scope of higher electrical conductivity values to identify the fractures and we divide bedding planes accord to the layered change of electrical conductivity in the contour map.Then,compared the identified fractures and bedding planes from the conductivity imaging figure with the FMI imaging logging figure,it is clear that the accuracy of Surfer software to identify fractures and bedding planes can be 80％.
