摘要： A system to monitor the retrieval of a well tool from a wellbore comprises a deployment member coupled to the well tool to retrievably insert the well tool in the wellbore. At least one first identification transducer is coupled to a top end of the well tool to transmit an identification signal during retrieval of the well tool. At least one second identification transducer is located at at least one axial location along a surface pressure control assembly to detect the identification signal. A controller is in data communication with the at least one second identification transducer to determine the position of the well tool relative to the pressure control assembly, and to output at least one command related to the position of the well tool relative to the pressure control assembly.

摘要： A bender bar is presented. The bender bar includes at least two pairs of piezoelectric elements arranged on an inert element to adjust the response frequency of the bender bar. In some embodiments, the piezoelectric elements can be stacked on the inert element. In some embodiments, the piezoelectric elements are symmetrically arranged with respect to the bender bar such that a gap is formed between piezoelectric elements arranged on the inert element.

摘要： A method and device are disclosed for determining the impedance of the cement bond between a borehole casing (140) and its wellbore (110). The invention uses a predicted resonance response as a baseline for determining from the observed resonance response the approximate impedance of the cement. Corrections are made to account for various defects in the casing normalizing the received resonance response.

摘要： In some embodiments, apparatus and systems, as well as methods, may operate to select an amount of imaging coverage associated with a substantially tubular object and a rotary scanner coupled to a telemetry system. Determining circumferential and longitudinal scan sampling intervals to provide substantially full coverage of the substantially tubular object may be included. Waveform sampling and transducer driving waveform parameters may also be determined according to an available data transmission bandwidth associated with the telemetry system.

摘要： A sonic or acoustic tool (200) is disclosed which includes a transmitter with reduced transmitter spawned noise. The transmitters are either monopole or dipole depending on the orientation of ports in a chamber divided by a piston driven by an actuator. The transmitter size is limited only by the diameter of the tools itself because the transmitters are oriented within the tool parallel to the axis of the tool.

摘要： An apparatus (figure 2) and method (figure 5) for determining fast and slow shear wave velocities and orientations in an anisotropic earth formation that reduces the error and ambiguity in calculating these parameters and eliminates the need for dipole receivers (104, 106) and multiple dipole sources (102). The apparatus generally includes a single dipole source (200) for generating an acoustic signal within a borehole. The acoustic logging tool contains multiple levels of receivers. At each level, four receivers, (204, 206, 208, 210) which may be conventional pressure transducers, receive shear/flexural wave signals which propagate along the borehole earth formation. These receivers measure the pressure fields from the wave signals. A processing device (214), preferably a UNIXtm based computer, interpolates the measured pressure fields between any two adjacent receivers. The processing device performs cross-component decomposition on the pressure field to determine shear wave orientation and velocity. Using the shear wave orientation and velocity the processing device determines transit time anisotropy, energy anisotropy, and slowness anisotropy.
