| 发明名称 | Optical fiber sensing with enhanced backscattering | ||
| 摘要 | An apparatus for estimating at least one parameter in a downhole environment includes: an optical fiber configured to be disposed in a borehole, the optical fiber having a property that causes intrinsic backscattering of signals transmitted therein. The property varies along a length of the optical fiber to generate a variable intensity of the backscattering, the intensity of backscattering varying along the optical fiber as a function of distance from an end of the optical fiber. The apparatus also includes a light source configured to send an optical signal into the optical fiber; and a detector configured to receive a return signal including backscattered signals. | ||

| 主权项 | 1. An apparatus for estimating at least one parameter in a downhole environment comprising: an optical fiber configured to be disposed in a borehole, the optical fiber having a property that causes intrinsic backscattering of signals transmitted therein, the property varying along a length of the optical fiber to generate a variable intensity of the backscattering, the intensity of backscattering increasing along a length of the optical fiber as a function of distance from an end of the optical fiber, a value of the intensity increasing with increasing distance from the end of the optical fiber; a light source configured to send an optical signal into the optical fiber; and a detector configured to receive a return signal including backscattered signals. | ||
