SYSTEMS AND METHODS FOR NEAR-INFRARED BASED WATER CUT MONITORING IN MULTIPHASE FLUID FLOW

摘要

Embodiments of systems and methods for characterizing multiphase flow (MPF) of fluid and enhancing measuring and monitoring of a full range of water cut in a portion of a pipe for oil-related operations are provided. An embodiment of a system can include a flow director to direct the MPF between paired wide-band near-infrared (NIR) emitters and detectors electrically coupled to signal conditioning, processing, and characterizing modules to determine absorption and scattering of MPF and define and display MPF characteristics for measuring and monitoring in oil-related operations.

1. A system to characterize multiphase flow (MPF) of fluid and enhance measuring and monitoring a full range of water cut for the total flow volume in a portion of a pipe for oil-related operations, the system comprising:
a flow director anchored within a portion of a pipe and positioned circumferentially within and closely adjacent an inner surface of the pipe to direct MPF through the portion of the pipe for a full range of water cut towards the inner surface of the portion of the pipe; a plurality of wide-band Near-Infra Red (NIR) sources, coupled to and positioned spaced-apart along the flow director within the portion of the pipe, to generate one or more wide-band NIR signals; a plurality of wide-band NIR detectors, mounted to and positioned circumferentially along an outer surface of the portion of the pipe and being correspondingly paired through at least one optical window with the plurality of wide-band NIR sources positioned within the portion of the pipe, to detect the one or more generated wide-band NIR signals passing through a medium; a photo multiplier electrically coupled to the plurality of wide-band NIR detectors to accumulate and amplify each of the generated one or more wide-band NIR signals and the detected one or more wide-band NIR signals; one or more processors electrically coupled to the photo multiplier and having associated non-transitory tangible computer-readable medium and being operable by the one or more processors to execute a set of instructions comprising:
processing responsive to each of an amplified generated one or more wide-band NIR signals and an amplified detected one or more wide-band NIR signals, to determine a plurality of wavelengths and corresponding frequencies associated with each of the amplified generated one or more wide-band NIR signals and the amplified detected one or more wide-band NIR signals, andanalyzing the plurality of wavelengths and frequencies to determine corresponding absorption and scattering associated with each of the amplified generated one or more wide-band NIR signals and the amplified detected one or more wide-band NIR signals so that the absorption and scattering define a plurality of MPF characteristics associated with the MPF through the portion of the pipe; and one or more displays in communication with the one or more processors to display MPF characteristics to measure and monitor in oil-related operations within the portion of the pipe.
