Sampling tool with dual flowline architecture

摘要

An optical fluid analyzer tool may have an evaluation flowline which receives a flow of fluid from a geotechnical formation and may have a cleanup flowline which receives another flow of fluid from the geotechnical formation. A flow routing system may be connected to the evaluation flowline and may be connected to the cleanup flowline. The flow routing system may establish isolated flow or commingled flow for the evaluation flowline and may establish isolated flow or commingled flow for the cleanup flowline. A sample chamber may be connected to the evaluation flowline and may be connected to the cleanup flowline. A first pump module may draw the fluid from the geotechnical formation, and an optical fluid analyzer connected to the cleanup flowline and the evaluation flowline may analyze the fluid.

1. An optical fluid analyzer tool, comprising:
inlets for obtaining fluid; an evaluation flowline connected to a first inlet and a flowline routing module; a cleanup flowline connected to a second inlet and the flowline routing module; a subsequent section of the evaluation flowline connected to the flowline routing module; a subsequent section of the cleanup flowline connected to the flowline routing module; a single optical fluid analyzer connected to the subsequent section of the cleanup flowline and the subsequent section of the evaluation flowline, wherein the single optical fluid analyzer comprises:
a lamp;a first optical fiber bundle configured to convey optical illumination from the lamp to first optical windows of the subsequent section of the evaluation flowline;a second optical fiber bundle configured to convey optical illumination from the lamp to second optical windows of the subsequent section of the cleanup flowline;a third optical fiber bundle configured to convey light from the first optical windows to a spectrometer; anda fourth optical fiber bundle configured to convey light from the second optical windows to the spectrometer; and wherein the flowline routing module is located between the single optical fluid analyzer and the inlets and is configured to selectively direct fluid from the evaluation flowline into the cleanup flowline, selectively direct fluid from the cleanup flowline to the evaluation flowline, selectively direct fluid from the evaluation flowline into a subsequent section of the evaluation flowline, and selectively direct fluid from the cleanup flowline into a subsequent section of the cleanup flowline.
