    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: A debris catcher can include an anchor connected to the wellbore tubular and a filter fixed to the anchor. The filter is positioned in a bore of the wellbore tubular and has an disintegrable accelerator material located in a carrier body. The debris catcher formed at least partially of a disintegrable accelerator material located in a carrier body is conveyed in a wellbore tubular. The disintegrable accelerator material is exposed to a downhole material in a subterranean fluid flowing through the wellbore tubular. The debris catcher filters the downhole material. 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 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: Slip elements for a downhole tool include an inner body portion that is substantially formed of a material that is degradable by dissolution in response to a dissolving fluid and a hardened, resilient, radially outer contact portion. The inner body portion may be formed of magnesium, aluminum or iron based powder.
