LOGGING-WHILE-DRILLING TOOL INCORPORATING ELECTRONIC RADIATION GENERATOR AND METHOD OF USING SAME

摘要

Logging-while-drilling tools incorporating an electronic radiation generator, such as an electronic X-ray generator, and a method for using the same are provided. One example of such a logging-while-drilling tool may include a circumferential drill collar, a chassis disposed radially interior to the drill collar, and an electronic X-ray generator and an X-ray detector disposed within the chassis. The electronic X-ray generator may emit X-rays out of the logging-while-drilling tool into a subterranean formation. The X-ray detector may detect X-rays that return to the logging-while-drilling tool after scattering in the subterranean formation, which may be used to determine a density and/or a lithology of the subterranean formation.

主权项

1. A logging-while-drilling tool comprising:
a circumferential drill collar having a space in the drill collar; and a pressure housing disposed in the space, wherein the pressure housing includes an electronic X-ray generator configured to emit X-rays out of the logging-while-drilling tool and into a subterranean formation and an X-ray detector configured to detect X-rays that return to the logging-while-drilling tool after scattering in the subterranean formation.
