Systems and methods for inspecting and monitoring a pipeline

摘要

Disclosed are systems and methods for inspecting and monitoring an inner surface of a pipeline. One system includes a pig arranged within the pipeline, one or more optical computing devices arranged on the pig adjacent the inner surface of the pipeline for monitoring at least one substance present on the inner surface. The optical computing devices include at least one integrated computational element configured to optically interact with the at least one substance and thereby generate optically interacted light, and at least one detector arranged to receive the optically interacted light and generate an output signal corresponding to a characteristic of the at least one substance. A signal processor is communicably coupled to the at least one detector of each optical computing device for receiving the output signal of each optical computing device and determining the characteristic of the at least one substance.

1. A system for inspecting and monitoring an inner surface of a pipeline, comprising:
a movable inline inspection device arranged within the pipeline; one or more optical computing devices arranged on the movable inline
inspection device adjacent the inner surface of the pipeline for monitoring at least one substance present on the inner surface, the one or more optical computing devices comprising:an electromagnetic radiation source configured to emit electromagnetic radiation that optically interacts with the at least one substance;at least one integrated computational element configured to optically interact with the at least one substance and thereby generate optically interacted light;a first detector arranged to receive the optically interacted light and generate an output signal corresponding to a characteristic of the at least one substance; anda second detector configured to generate a compensating signal indicative of radiating deviations of the electromagnetic radiation source; and a signal processor configured to computationally combine the output signal of the first detector and the compensating signal of the second detector and provide a resulting output signal.
