System and Method for Quantifying Vug Porosity

摘要

Methods and systems acquiring acoustic data utilizing a downhole tool conveyed within a borehole extending into a subterranean formation. The downhole tool is in communication with surface equipment disposed at a wellsite surface from which the borehole extends. Techniques involve operating at least one of the downhole tool and the surface equipment to generate a histogram based on the acoustic data, normalizing the histogram, and calculating a vug index based on the normalized histogram and based on a threshold of the normalized histogram. A vug porosity quantity may be determined based on the calculated vug index.

1. A method, comprising:
acquiring acoustic data from an inspected region of a borehole extending into a subterranean formation by utilizing a downhole tool conveyed within the borehole, wherein the downhole tool is in communication with surface equipment disposed at a wellsite surface from which the borehole extends; and operating at least one of the downhole tool and the surface equipment to:
generate a histogram based on the acoustic data associated with the inspected region;normalize the histogram;calculate a vug index based on the normalized histogram and based on a threshold of the normalized histogram; anddetermine a vug porosity quantity of the inspected region based on the calculated vug index.
