摘要： A system for driving an arm radially outward from a work string axis includes a pivot block coupled to the arm at a first coupling, the arm rotating about the first coupling in a first direction to move from a stored position to an expanded position, and about the first coupling in a second direction to move from the expanded position to the stored position. The system also includes a biasing member that drives movement of the arm in the first direction. The system further includes a chamber for storing the biasing member within a pivot block diameter when the arm is in the stored position.

摘要： An energy storage system is disclosed. The energy storage system comprises an energy storage device configured to operate above ambient temperature, and a thermal insulator at least partially surrounding the energy storage device, wherein heat losses from one or more other devices are received within the thermal insulator to provide heat energy to the energy storage device. Utilizing heat losses from one or more other devices, such as associated electronic components, enables the energy storage device to be maintained at its elevated operational temperature for longer providing extended battery life. In the application of wireline logging, this results in more data log available per trip in a well.

摘要： A borehole resistivity instrument for use in a borehole drilled within a geologic formation includes an emitting electrode and an imaging electrode. The borehole resistivity instrument also includes a current isolator positioned between the emitting electrode and the imaging electrode. The current isolator prevents a substantial portion of the electric current emitted from the emitting electrode from passing to the imaging electrode through the borehole.

摘要： A current leakage detector for detecting current leakage between a power source and a load including a first sensing coil and a second sensing coil positioned opposite the first sensing coil. The current leakage detector further includes a magnetic field sensor proximate the first sensing coil and the second sensing coil and the magnetic field sensor has a response range. The current leakage detector also includes a bias circuit configured to adjust the response range of the magnetic field sensor. A method for detecting current leakage includes providing a first sensing coil and a second sensing coil. The method continues with the steps of providing a magnetic field sensor in proximity to the first and second sensing coils and providing a bias circuit. The method continues with the step of utilizing the bias circuit to place the response of the magnetic field sensor within a preferred response range.

摘要： Apparatus and method for cooling internal components of a down-hole well drilling apparatus. Components of the well drilling apparatus are encased in an inner canister that is further encased in an outer canister creating a void between the inner canister and the outer canister. Further, a plurality of moveable barriers is disposed between the inner canister and the outer canister and contains a heat transfer fluid. A plurality of agitators add mechanical energy to the plurality of moveable barriers compressing and expanding, while repositioning, the heat transfer fluid and creating a heat pump based on a reverse Stirling cycle to remove heat from the cooler inner canister and transfer the heat to the hotter environment outside the outer canister.

摘要： A method and apparatus for determining the fluid permeability of an earth formation is described. An instrument comprising an acoustic source and acoustic and electrokinetic sensors is located in a borehole at a site of interest. The acoustic source is fired and the resulting variations in pressure and electric field generated are measured and recorded. The Biot equation, and an equation for the streaming potential coupled to fluid displacement terms, is solved using finite element analysis to give an expected pressure waveform and electrokinetic waveform based on estimated earth formation properties. By comparison of the measured waveforms and those calculated from the equations, the actual permeability of the earth formation can be deduced.
