    摘要: A method of operating a distributed acoustic sensing (DAS) system and a DAS system are described. The method includes disposing the DAS system to measure acoustic signals in a borehole, positioning a vibration tool at a specified depth in the borehole, and obtaining two or more DAS signals, obtaining at least one of the two or more DAS signals while the vibration tool is activated at a respective specified frequency and a respective specified amplitude. The method also includes calibrating the DAS system based on the two or more DAS signals, and the specified depth, the respective specified frequency, and the respective specified amplitude.

    摘要: A method for calibrating distributed temperature sensing (DTS) systems is disclosed. The method includes: receiving temperature data associated with one or more locations along a length of an optical fiber; calculating a set of unique calibration coefficients specific to each of the one or more locations along the fiber length; and applying the set of calibration coefficients specific to each of the one or more locations along the fiber length to the temperature data for calibrated correction thereof. Also disclosed is a system for calibrating DTS data and a wellbore for providing calibrated DTS data.

    摘要: A method, apparatus and system for determine a parameter of a structure is disclosed. A fiber optic cable is coupled to a member. The fiber optic cable includes at least a first core helically arranged in the fiber optic cable that includes at least a first sensor and a second sensor. A first measurement related to the parameter is obtained at the first sensor, and a second measurement at the second sensor related to the parameter is obtained at the second sensor. A difference between the first and second measurements is used to determine the parameter.
