METHOD OF OBTAINING CHARACTERISTICS OF GEOLOGICAL FORMATION INTERSECTED BY WELL Russian patent published in 2012 - IPC G01V3/34 

FIELD: physics.

SUBSTANCE: present invention seeks to improve existing methods of imaging wells by creating, as a non-restrictive example, methods which are capable of "filling spaces" between borehole probe pads on well image logs with simulated images. According to versions of the invention, a method of obtaining characteristics of a geological formation which intersects a first well is disclosed. The method involves a) sampling one or more sets of measurement data obtained by at least one measuring tool on one or more sections of a logged well, for the first well, at least one other well or both wells to obtain a diagram of the well image; b) selecting depth intervals of the image well diagram as training samples for input into a multipoint geostatistical model; c) determining imitations based on the picture for each training sample using at least one template with a pixel structure for the multipoint geostatistical model to obtain pictures of the training sample; d) using the imitations based on the picture of each training sample to assign each training sample the training sample picture; e) constructing from the training sample pictures one or more diagrams for the full circular image of the wall of the first well; and f) repeating steps (a)-(e) for one or more sections of the logged well in order to construct full circular images of the wall of the well from successively adjacent training samples.

EFFECT: formation of a full circular image of the wall of the well from electric logging diagrams for imaging the well, improving existing methods of imaging wells by creating, as a non-restrictive example, methods which are capable of "filling spaces" between borehole probe pads on well image logs with simulated images.
