摘要： A wellbore seismic source includes a sparker electrically coupled to a power source. The sparker is disposed in a pressure-sealed canister, wherein the canister is at least partially filled with liquid. At least one of the pressure of the liquid and the energy discharged by the power source through the sparker is selected to cause emission of acoustic energy at a selected frequency.

摘要： A method for operating an impulsive type seismic energy source in a firing sequence having at least two actuations for each seismic impulse to be generated by the source. The actuations have a time delay between them related to a selected energy frequency peak of the source output. One example of the method is used for generating seismic signals in a wellbore and includes discharging electric current through a spark gap disposed in the wellbore in at least one firing sequence. The sequence includes at least two actuations of the spark gap separated by an amount of time selected to cause acoustic energy resulting from the actuations to have peak amplitude at a selected frequency.
摘要翻译：一种用于在击发序列中操作脉冲型地震能量源的方法，其具有用于由源产生的每个地震脉冲的至少两次致动。这些启动在它们与源输出的选定能量频率峰值之间具有时间延迟。该方法的一个示例用于在井眼中产生地震信号，并且包括以至少一个点火顺序将设置在井眼中的火花隙排出电流。该序列包括火花间隙的至少两次致动，所述至少两次激励间隔了所选择的时间量，以使致动产生的声能在所选频率处具有峰值振幅。

摘要： A drill bit assembly is provided for releasably retaining a polycrystalline diamond compact drill bit cutter. Two adjacent cavities formed in a drill bit body house, respectively, the disc-shaped drill bit cutter and a wedge-shaped cutter lock element with a removable fastener. The cutter lock element engages one flat surface of the cutter to retain the cutter in its cavity. The drill bit assembly thus enables the cutter to be locked against axial and/or rotational movement while still providing for easy removal of a worn or damaged cutter. The ability to adjust and replace cutters in the field reduces the effect of wear, helps maintains performance and improves drilling efficiency.
