    摘要： An optic sensor for use in a well is provided. The sensor can be configured to sense downhole conditions, such as temperature, pressure, or stress, either individually or in combination. The optic sensor has a sensor housing that defines a chamber. The sensor housing also defines a region that is responsive to an external force. An optic fiber extends through the housing. The optic fiber has a dielectric boundary that resides within the housing chamber , and has a refractive index variation that provides maximum reflectivity at a central reflectivity wavelength, the central reflectivity wavelength correspondingly shifting with respect to an expansion or contraction of the region. In a further aspect of the invention, the optic fiber has a second dielectric boundary spaced apart from the first dielectric boundary. The second dielectric boundary is within the chamber and has a refractive index variation that provides maximum reflectivity at a central reflectivity wavelength sufficiently dissimilar to the first dielectric boundary. The second dielectric boundary floats in the cavity such that the second dielectric boundary is responsive to a temperature change within the sensor housing.

    摘要： A circulating valve and associated methods of servicing a well provide reliable operation, economical manufacture, and convenient maintenance in the circulating valve which is responsive to flow of fluid therethrough, and increased versatility in well servicing operations utilizing the valve. In a preferred embodiment, a circulating valve includes an upper case having a reverse circulating port formed radially therethrough, a circulating case having a circulating port formed radially therethrough, a lower adapter, a mandrel having a flow port formed radially therethrough, a biasing member, a ratchet, an inner sleeve, and a one-way flow restrictor carried on the mandrel. In an open configuration, fluid communication is permitted between the flow and circulating ports, and between the reverse circulating port and the flow restrictor. In a closed configuration, fluid communication is not permitted radially through the valve. A predetermined pressure differential across the mandrel is utilized to configure the valve in its open and closed configurations.

    摘要： Purging of fiber optic conduits in subterranean wells. A downhole optical sensing system includes an optical line, at least two tubular conduits, one conduit being positioned within the other conduit, and the optical line being positioned within at least one of the conduits, and a purging medium flowed in one direction through one conduit, and flowed in an opposite direction between the conduits. A method of purging a downhole optical sensing system includes the steps of: installing at least two conduits and an optical line in a well as part of the sensing system, one conduit being positioned within the other conduit, and the optical line being positioned within at least one of the conduits; and flowing a purging medium through the conduits in the well, so that the purging medium flows in one direction through one conduit and in an opposite direction between the conduits.

    摘要： A method of delivering a desired relatively high optical power to a well tool in a subterranean well can include coupling to an optical waveguide an optical source which combines multiple optical frequency ranges, respective centers of the frequency ranges being separated by at least a peak shift frequency in a Raman gain spectrum for a corresponding pump wavelength generated by the optical source, and transmitting the desired optical power to the well tool via the optical waveguide positioned in the well. Another method of delivering optical power to a well tool in a subterranean well can include coupling to an optical waveguide an optical source, the optical source comprising a sufficient number of lasing elements to transmit the optical power, with the optical power being greater than a critical power for stimulated Brillouin scattering in the waveguide.

    摘要： An RCD can include a housing assembly containing a bearing assembly and a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents displacement of the housing assembly relative to the body. A method of remotely operating a clamp device can include rotating a threaded member which is secured relative to an RCD body, and displacing a clamp section in response to the threaded member rotation, thereby selectively securing and releasing a bearing assembly and an annular seal relative to the body. Another RCD can include a rotating seal which seals an annulus between a tubular string and a body of the RCD, and a remotely operable clamp device which selectively permits and prevents access to an interior of the body, the clamp device including a motor which rotates a threaded member.
