Method and apparatus for sensing an environmental parameter in a wellbore

摘要

An apparatus and method for use in a wellbore includes a sensor having an optical fiber and a strain sensitive member that is continuously bonded to a portion of the optical fiber. The optical fiber portion is strained in response to an environmental parameter of the wellbore that is being monitored by the sensor. The strain on the optical fiber portion changes a property of light signals propagating in the optical fiber.
