Downhole mass spectrometry

摘要

A method comprising using a first mass analyzer of a downhole tool to isolate specific ions within a sample received in the downhole tool, using a second mass analyzer of the downhole tool to stabilize the ions isolated by the first mass analyzer, and using a third mass analyzer of the downhole tool to catalog the stabilized ions.

主权项

1. A method, comprising:
flowing drilling mud through a downhole tool positioned within a wellbore extending through a subterranean formation; receiving a sample in the downhole tool; using an ion source of the downhole tool to chemically ionize a molecule of the sample by at least ionizing a chemical reagent, wherein the chemical reagent is a component of the drilling mud, and wherein ionizing the chemical reagent causes an ionization plasma that reacts with the sample to generate specific ions; using a first mass analyzer of the downhole tool to isolate the specific ions within the sample received in the downhole tool, wherein the downhole tool is configured to be positioned within the wellbore extending through the subterranean formation; using a second mass analyzer of the downhole tool to stabilize the ions isolated by the first mass analyzer; and using a third mass analyzer of the downhole tool to catalog the stabilized ions.
