FILTER WHEEL SOURCE ASSEMBLY FOR DOWNHOLE SPECTROSCOPY |
摘要 |
A downhole fluid analysis tool has a tool housing and a fluid analysis device. The tool housing is deployable downhole and has at least one flow passage for a fluid sample. The fluid analysis device is disposed in the tool housing relative to the flow passage. Inside the device, one or more sources generate a combined input electromagnetic signal across a spectrum of wavelengths, and a routing assembly routes generated signals into the reference and measurement signals. At least one wheel having a plurality of filters is rotated to selectively interpose one or more of the filters in the paths of the reference and measurement signals. |
