摘要:
Optical analysis systems, methods, and apparatuses for analyzing fluids may be useful for in situ monitoring fluids that relate to cementing operations. For example, a method may include containing a cement fluid composition in a flow path comprising a wellbore; and optically interacting the cement fluid composition with an integrated computational element, thereby generating an output signal corresponding to a characteristic of the cement fluid composition, the integrated computational element being coupled to a tool.

Optical analysis systems may be useful in monitoring fluids relating to cementing operations in or near real-time, e.g., for location and/or the status of a cement setting process. For example, method may involve containing a cement slurry within a flow path, the cement slurry having a chemical reaction occurring therein; and optically interacting the cement slurry with an integrated computational element, thereby generating an output signal corresponding to a characteristic of the chemical reaction.

Optical analysis systems may be useful in systems and methods for various properties of fluid cement compositions. For example, a method may include generating with an optical computing device a plurality of output signals corresponding to a plurality of time points and a characteristic of a fluid cement composition at a monitoring location within a flow path, the optical computing device having an electromagnetic radiation source configured to optically interact with the fluid cement composition and an integrated computational element, wherein the integrated computational element is configured to produce and convey optically interacted light to a detector which generates a plurality of output signals corresponding to the characteristic at a plurality of time points; receiving the plurality of output signals with a signal processor communicably coupled to the detector; and determining a difference between at least two of the output signals with the signal processor.

Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof. Additional apparatus, systems, and methods are disclosed.

An apparatus for analyzing a fluid comprises a chamber to receive a fluid sample. A pump reduces a pressure in the chamber below a vapor pressure of a component of the fluid sample. At least one light system provides a light at a predetermined modulation frequency to the fluid sample. An acoustic sensor detects an acoustic signal caused by the interaction of the light and the fluid sample. A controller relates the acoustic signal to at least one chemical component of the fluid sample.
