摘要： A transducer configuration for use in acoustically imaging a target region behind an acoustically reflective layer includes a sonde having a geometrical center and constructed and arranged to support a plurality of transducers. The system includes a first transducer disposed within the sonde at a first distance from the geometrical center for generating a first acoustic pulse and for receiving a first acoustic signal. The acoustic signal comprises a first reflection from the reflective surface, a first set of fluid multiples arising from reflections between the reflective layer and a surface of the first transducer, and a first signal associated with the target area. The system also includes a second transducer disposed within the sonde at a second distance from the geometrical center for generating a second acoustic pulse and for receiving a second acoustic signal. The second acoustic comprises a second reflection from the reflective surface, a second set of fluid multiples arising from reflections between the reflective layer and a surface of the second transducer and a second signal associated with the target area. A mechanism for receiving and processing signals received by the first and second transducers at time intervals which occur between receipt of the first and second sets of fluid multiples, respectively, wherein signal values at time intervals between receipt of fluid multiples provide acoustic waveforms associated with the target region. Each target region, therefore, has a time interval on at least one of the two waveforms which is free of fluid multiples.

摘要： A transducer configuration of an acoustic sensing tool for determining the consistency of a first medium disposed between a layer having a greater acoustic reflectivity than the first medium and a second medium, the sensing tool including a rotating head, wherein the tool comprises first, second and third transducer pairs in a spaced apart configuration, each pair comprising a transmitting transducer for transmitting an acoustic radiation signal in an insonified zone, and receiving transducer having a receiving radiation pattern in a insonified zone, wherein the space between the transmitting and receiving transducers in each pair is constructed and arranged to allow the transmitting and receiving insonified zones to intersect behind but not in the acoustically reflective layer to null reverberation energy therefrom. The tool also includes a centerline of radiation from each transmitting transducer that propagates and refracts through the reflective layer such that all transmitting centerlines intersect in an intersection near voxel, wherein the intersection voxel is interrogated by all three transducer pairs substantially simultaneously at nearly a single azimuthal head position, such that any occlusion is interrogated from three different directions, thereby facilitating determination of occlusion surface orientation.

摘要： An electrical feedthrough connector is illustrated for use in down hole sondes and other logging tools exposed to pressures of up to 25,000 psi and temperatures of 500.degree. F. It incorporates an elongate conductive metal pin surrounded by a concentric sleeve of insulative material and on the exterior of that, there is an elongate metal clad sleeve. This defines the structure so that the feedthrough can be mechanically anchored on a bulk head. In addition, at the end exposed to high pressure, the central conductor is totally covered by an elongate insulative sleeve. On the exterior of that, there is an elongate all encompassing resilient boot which extends substantially up the length of cable connected with the feedthrough connector but which is in contact only with surfaces which are insulated from the central conductor. This boot is formed of resilient rubber like material and is capable of deforming. It excludes the intrusion of fluids in the well borehole environment where the device is used.

摘要： A high pressure high temperature hermetically sealed electrical connector pin construction is set forth for use in down hole logging tools. On exposure to 28,000 psi at elevated temperatures, the present apparatus is able to handle such pressure and temperature cycling. Moreover, an elongate pin having two ends for forming electrical connections is used, the pin having a shoulder, a central threaded portion on one side of the shoulder and is formed of conductive metal that joins with a plastic body which is bonded thereto either by in situ molding to the pin or by an epoxy resin and the pin further threads to the body. In a multipin construction, the body is a circular insert for a surrounding cylindrical steel housing.

摘要： A method and apparatus for in-situ characterization of downhole fluids in a wellbore using ultrasonic acoustic signals. Measurements of the speed of sound, attenuation of the signal, and acoustic back-scattering are used to provide qualitative and quantitative data as to the composition, nature of solid particulates, compressibility, bubble point, and the oil/water ratio of the fluid. The tool generally comprises three sets of acoustic transducers mounted perpendicular to the direction of the flow. These transducers are capable of operating at different frequencies so that the spectrum of the acoustic signal can be optimized. The apparatus is capable of operating downhole to provide real time information as to conditions in the well.

摘要： A fluid property monitor includes a transducer assembly to impart multiple frequency energy to a conduit in one or more modes and to receive resonant frequency energy from the conduit. The resonant frequency energy is responsive to the imparted energy, the conduit and a fluid in the conduit. The fluid property monitor can also be defined as including: a frequency signal generator connected to cause multiple frequency energy to be transferred to a conduit having a fluid to be monitored; and a spectral analysis signal processor connected to receive and process electrical signals generated in response to vibrations propagated through the conduit and the fluid in the conduit in response to transferred multiple frequency energy. Particular implementations can be adapted as a densitometer, a coherent flow detector, and other particular fluid parameter detectors. A method of monitoring a fluid includes: imparting multiple frequency vibration-inducing energy to a conduit and fluid system; and sensing a plurality of frequency signals from the conduit and fluid system responsive to at least part of the imparted multiple frequency vibration-inducing energy. This method can also include determining at least one characteristic of the conduit and fluid system in response to the sensed plurality of frequency signals.
