Abstract: In the study of fracture reservoirs, determination of effectiveness of fractures is difficulty in well logging interpretation. The rich information, which includes the fracture effectiveness, is extracted from the electricity imaging logging, the dipole shear wave imaging logging, as well as dual laterolog, the fracture effectiveness of Igneous Rock is evaluated by using logging data. Through practical application of fracture reservoir of Igneous Rock in 69th area of the Junggar Basin, it is confirmed by using the Stoneley wave, the shear wave anisotropy of the dipole shear wave imaging logging and unifying the imaging logging to qualitatively analyze the fracture effectiveness of igneous rock to be possible. At the same time, the evaluating method of fracture effectiveness is given by using dual laterolog when these new logging information lacks. Study result shows that these methods can rapidly and expediently determine the fracture effectiveness, and it can provide bases for field development.

Key words: Igneous Rock, fracture, effectiveness, Stoneley wave, anisotropy
