摘要： A scintillation detector (10) includes a scintillation crystal (14) and a shock absorbing member (76) circumscribing the crystal (14). A sleeve (98) circumscribes the shock absorbing member (76) which, in turn, is circumscribed by a housing (12). The sleeve (98) provides for substantial controlled radial loading on the crystal (14). A method of manufacturing the detector (10) includes placing the crystal (14) and shock absorbing member (76) into the sleeve (98), compressing the sleeve 98 and inserting the compressed sleeve (98) into the housing (12) such that the sleeve (98) substantially maintains its compression. The radial stiffness causes vibration induced counts to occur at an excitation frequency which is above the operational bandwidth of the radiation measurements, thereby excluding vibration induced counts for radiation measurements.

摘要： A casing construction for use, for example, in a nuclear logging tool, is made of two types of material. The tool case (10) is formed of a high density and high atomic number material (relatively opaque to gamma radiation) such as tungsten, and a more transparent window (28) is made of beryllium for example. The window is preferably sealed in the case and a coating is preferably provided on the window to protect it against wear and corrosion. A preferred coating is of thin electroless plated nickel, topped with a thin layer of titanium carbide.

摘要： Well drilling materials such as muds and additives therefor are monitored for their gamma ray activity before use, and the effects of the activity, on well logging measurements at depth in a well, are calculated. Thus, accurate correction of well logging measurements to take account of the background effect of the materials is achieved. A test cell for measuring the activity of the materials comprises a pan 10 with an upstanding central pipe 12 for receiving a scintillometer probe 11. Material to be tested (13) is placed in the pan.

摘要： An electric impulse drilling system is disclosed comprising a drill string, a bottom hole assembly (BHA) (400) coupled to the drill string. The BHA (400) comprises a motor (402) configured rotate, a power generator (408) configured to generate electrical power from the rotation of the motor (402), a high voltage generator (412) configured to generate a high voltage from the electrical power generated by the power generator (408), at least two electrodes (102, 104) configured to discharge the high voltage from the high voltage generator (412) through a downhole formation, and one or more quantum particle or quantum particle information detectors (520). The one or more quantum particle or quantum particle information detectors (520) are disposed within at least one of the at least two electrodes (102, 104) configured to interpret quantum particles displaced by the discharge of the high voltage through the downhole formation.
