Systems and methods for displaying logging data

摘要

Borehole data presentation systems and methods that facilitate communication of volumetric logging data to a surface processing system for presentation to a driller or other user interested in visualizing the formations surrounding a borehole. The disclosed systems optionally tailor the telemetry stream to match the chosen display technique, thereby maximizing the logging system utility for the driller. Variable opacity of certain data regions or certain data discontinuities greatly facilitates data comprehension, particularly when true three-dimensional display technologies are employed. Holographic or stereoscopic display technologies may be employed to show the three-dimensional dependence of measured formation properties such as resistivity, density, and porosity. Alternatively, the radial axis can be used to represent a formation parameter value, thereby enabling cylindrical cross-plots of multiple measurements. The user can control viewing position and orientation to more fully explore the three dimensional representation.

1. A logging method that comprises: receiving formation measurements from at least one logging tool, wherein the formation measurements are volumetric data measurements including at least one of a resistivity, a density, and a porosity measurement, wherein said received volumetric data measurements are determined by calculating differences between measured data values; and displaying a three-dimensional holographic representation of the formation, wherein the representation shows the volumetric data's dependence on axial distance, azimuth, and radial distance.
