| 发明名称 | Location dependent calibration for distributed temperature sensor measurements | ||
| 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. | ||

| 主权项 | 1. A method for calibrating distributed temperature sensing (DTS) systems, comprising: disposing a length of an optical fiber having a plurality of sensing locations in a chamber; controlling, by a temperature controller, a temperature within the chamber to expose each of the plurality of sensing locations in the chamber to a first temperature; receiving temperature data associated with each of the plurality of locations along the length of an optical fiber for the first temperature; calculating a set of unique calibration coefficients specific to each of the plurality of locations in the chamber; and applying the set of calibration coefficients specific to each of the plurality of sensing locations along the fiber length to subsequent temperature data for calibrated correction thereof, the subsequent temperature data collected from measurements performed by disposing the optical fiber in an environment outside of the chamber. | ||
