摘要： A sensor for detecting well conditions includes at least one transducer positioned at an end of the carrier. The carrier is positioned adjacent to and exposed to a wellbore wall and the transducer is configured to generate mechanical waves in the carrier. The carrier conveys the mechanical waves and has one or more sections initially free of a physical deformation that causes reflection of the mechanical waves. The sections physically deform to cause reflected mechanical waves when subjected to a loading from the formation. The transducer generates a signal representative of reflected mechanical waves received at the end of the carrier. The location of the loading is estimated using the received signal. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the general subject matter of the technical disclosure.

摘要： Systems and methods for monitoring temperature distribution in downhole equipment using magnetostrictive probes. In one embodiment, an ESP motor has a stator with a rotor and shaft rotatably positioned within the stator. Magnetostrictive sensors are positioned within the motor. Each magnetostrictive sensor has a transducer, a probe, and electronic circuitry coupled to the transducer. The circuitry generates an initial electrical signal that is conveyed to the transducer. The signal passes through one or more coils in the transducer, generating magnetic fields that induce an acoustic signal in the probe. The acoustic signal propagates through the probe and waves are reflected from reflection points in the probe. The transducer senses the reflected acoustic waves and provides corresponding electrical signals to the circuitry, which determines timing intervals associated with the reflected waves and uses this information to determine temperatures at one or more locations in the probe (hence in the monitored equipment).

摘要： Systems and methods for the construction of components such as laminations for the stator core of an ESP motor wherein particles of different materials are mixed and pressed together at an elevated temperature to form a composite material in the desired lamination shape. The materials are selected to provide characteristics such as high magnetic permeability from one material and high thermal conductivity from the other material. The particles of the different materials are pressed together at a temperature that is sufficiently high to fuse the particles together and form a composite material, but is also sufficiently low that the materials are not sintered. The individual materials therefore retain their original characteristics, and the composite material benefits from the high magnetic permeability of the first material and the high thermal conductivity of the other material.

摘要： Introducing a fluid composition and a heat-generating fluid into a wellbore may improve timing and/or conditions of generating in situ heat downhole. The generated heat may be used to melt wax, and dissolve paraffins and asphaltenes or other deposits within the wellbore or in the reservoir itself. The fluid composition may include a base fluid and a metallic powder having a plurality of metallic powder particles. The base fluid may be or include a drilling fluid, a completion fluid, a stimulation fluid, a workover fluid, an activation fluid, and mixtures thereof. Each metallic powder particle may have a metallic particle core, and a coating disposed on the metallic particle core having a coating material. The metallic particle core may be released from the metallic powder particle. A heat-generating fluid may contact the released metallic particle core and thereby generate heat.
