    摘要: A system to determine the mixture of fluids in the deviated section of a wellbore comprising at least one distributed temperature sensor adapted to measure the temperature profile along at least two levels of a vertical axis of the deviated section. Each distributed temperature sensor can be a fiber optic line functionally connected to a light source that may utilize optical time domain reflectometry to measure the temperature profile along the length of the fiber line. The temperature profiles at different positions along the vertical axis of the deviated wellbore enables the determination of the cross-sectional distribution of fluids flowing along the deviated section. Together with the fluid velocity of each of the fluids flowing along the deviated section, the cross-sectional fluid distribution enables the calculation of the flow rates of each of the fluids. The system may also be used in conjunction with a pipeline, such as a subsea pipeline, to determine the flow rates of fluids flowing therethrough.

    摘要: A wellbore cleaning assembly is run into a wellbore to be cleaned on a work string. The cleaning assembly comprises a number of cleaning elements for cleaning a wall of the wellbore; and an oscillator coupled to the at least one cleaning element by a force transmission element, for generating an axial oscillating movement of the at least one cleaning element relative to the work string.

    摘要: The invention relates to a wellbore cleaning assembly, wellbore cleaning apparatus comprising a wellbore cleaning assembly, and to a method of cleaning a wellbore. In an embodiment of the invention, a wellbore cleaning assembly (10) is disclosed which is run into a wellbore (14) to be cleaned on a work string (20). The cleaning assembly (10) comprises a number of cleaning elements (24, 26, 28, 30) for cleaning a wall (22) of the wellbore (14); and an oscillator (36) coupled to the at least one cleaning element (24, 26, 28, 30), for generating an oscillating movement of the at least one cleaning element (24, 26, 28, 30) relative to the work string (20).
