Abstract

According to the design principle, structure and logging mode of micro-resistivity image logging instrument, this paper studied the electrical image logging response characteristics to fractured reservoir by three-dimensional finite element method, simulated the logging response changes with the fracture width, fracture extension depth, resistivity contrast and fracture dip, and researched the resolution of the instrument to the two horizontal fractures. The results show that the changes of fracture width and resistivity contrast have obvious influence on the logging response. The logging response to high angle fracture appears obvious asymmetry. If the double horizontal fracture spacing is less than five millimeter, they can not be distinguished. This research result is helpful for using electrical image logging to identify and quantitatively evaluate fracture.
