    摘要: Systems and methods for delivering an injection fluid into a subterranean well include an injection tool having an injection tool body with an internal cavity. A fluid chamber is located within the internal cavity. A heating chamber includes a pipe segment arranged parallel to the central axis. A one way valve provides a fluid flow path for the injection fluids to travel in a downhole direction through the one way valve, and prevents the flow of fluids through the one way valve in an uphole direction. A fiber optic cable extends to the pipe segment, the fiber optic cable operable to deliver a laser radiation to the pipe segment, heating the pipe segment. The injection tool body provides a fluid flow path from the one way valve to an outside of the injection tool.

    摘要: An example laser tool is configured to operate within a wellbore of a hydrocarbon-bearing rock formation. The laser tool includes one or more optical transmission media. The one or more optical transmission media are part of an optical path originating at a laser generator configured to generate a laser beam having an axis. The one or more optical transmission media are for passing the laser beam. The laser tool includes an optical element that is part of the optical path. The optical element is for receiving the laser beam from the one or more optical transmission media and for output to the hydrocarbon-bearing rock formation. The laser tool includes a color applicator head for discharging one or more coloring agents to a surface in the wellbore in a path of the laser beam.

    摘要: A method for monitoring hydrate formation in an interior of a tube may include deploying a first hydrate controller device at a first location on an exterior surface of the tube. The method may include deploying a second hydrate controller device at a second location on the exterior surface of the tube. The method may include transmitting, by the first hydrate controller device, first acoustic signals towards the interior of the tube. The first acoustic signals may include a first frequency value and a first amplitude value associated to a transmission power level. The method may include receiving, by the second hydrate controller device, the first acoustic signals. The method may include measuring, by the second hydrate controller device, a reception power level of the first acoustic signals.

    摘要: An example laser tool that operates within a wellbore is configured to combine a purging medium and a laser beam. The laser tool includes an integrator configured to receive the laser beam from a laser head and to combine the laser beam and the purging medium. A conduit is configured to generate a laminar flow from the purging medium and to produce an output that includes the laminar flow and the laser beam. The output is directed by the conduit towards a target within the wellbore. At least part of the laser tool is configured for rotation to cause the output to rotate during application of the output to the target.

    摘要: Tools, processes, and systems for in-situ fluid characterization based on a thermal response of a fluid are provided. The thermal response of a downhole fluid may be measured using a downhole thermal response tool and compared with thermal responses associated with known fluids. The properties of the downhole fluid, such as heat capacity, diffusivity, and thermal conductivity, may be determined by matching the thermal response of the downhole fluid with a thermal response of a known fluid and using the properties associated with the known fluid. The composition of the downhole fluid may be determined by matching the viscosity of the downhole fluid to the viscosity of known fluid. A downhole thermal response tool for cased wellbores or wellbore sections and a downhole thermal response tool for openhole wellbores or wellbore sections are provided.
