Method for characterizing the texture heterogeneities of geological formations traversed by a borehole

摘要

The invention relates to a method for characterising, with regard to the texture heterogeneities, a geological formation traversed by a borehole. Starting with an image of the borehole wall representative of the variations in a physical parameter of the formation along the longitudinal direction of the borehole and along the periphery of the wall, such as the image provided by the FMS (Formation Microscanner) device from Schlumberger, geological features corresponding to a heterogeneity of a specific morphological type are deduced, and the variation, along the longitudinal direction of the borehole, in at least one attribute defined for this type of heterogeneity is determined. Application to the detection of vacuoles. IMAGE
