Method of representing the trajectory of at least one borehole in a space- time domain

摘要

A method for representing in a space-time domain the trajectory of at one borehole by:PPa) producing a velocity-depth model (4) tied to the borehole (1), geologically representative of said area and including a representation of said trajectory (5) of said borehole; PPb) selecting at least one point (A) on or near said trajectory, said point (A) being defined by its space coordinates and by at least one dip- azimuth data pair; and PPc) at least modelling in a synthetic stack domain (9) the image (a) of the selected point (A), said image (a) being defined by space-time coordinates and by a dip-time vector and being obtained by zero offset ray tracing in the velocity-depth model (4).
