    摘要： In an oil well instrumentation system, the downhole sensor system is controlled by a computer which is powered-on only during sampling movement. An independent circuit, continuously powered, detects significant sensor rate-of-change values whereby the computer-sampling equipment is powered-on. A self-contained memory gauge includes either semiconductor or magnetic core memory for retaining downhole information related to sampled parameters, such as borehole temperature and pressure. A microprocessor-based computer manages the power utilization by independently and selectably energizing and deenergizing different sections of the gauge. The magnetic core memory is tested for operability, and the addressing of the magnetic core memory is adjusted in accordance with any inoperable memory locations. Samples of the monitored environmental conditions can be taken at variable rates dependent upon software monitoring of the condition, the remaining battery life and the remaining memory capacity and in response to hardware monitored pressure changes. Each sample can be taken to a selectable resolution. A watchdog circuit monitors the microprocessor to insure that it is operating within a preselected time limit.

    摘要： A physical condition in a well bore is sampled and information taken from the sample is recorded by a method of conserving electrical energy in performing such sampling and recording. The method sequentially energizes and de-energizes a plurality of different electrical circuits within the downhole apparatus with which the physical condition is detected and in which the information is recorded. The method determines when the next sample is to be taken and, depending upon how much time remains until the next sample, de-energizes the apparatus to conserve energy.

    摘要： The power-conversing apparatus includes a plurality of independently energizable electrical circuits used in receiving electrical signals from a transducer which senses an environmental condition, in processing the electrical signals, and in storing information related to the detected environmental condition. The apparatus further includes a power control circuit for continuously providing electrical power to at least one of the electrical circuits and for independently switchably providing electrical power to selectable ones of at least two others of the separately energizable circuits.

    摘要： A method of testing a magnetic core memory includes writing a test bit to each storage location addressed by each X-drive/X-sink transistor pair and each Y-drive/Y-sink transistor pair to determine which transistor or transistors of each pair is or are inoperable. Once this determination is made, a memory status map is created designating the inoperable transistors. Thereafter, the map contents are converted into an address field for matching against a selected memory address. If the selected memory address calls for an inoperable transistor, as indicated by a comparison with the address field, this is detected and the address changed until only operable transistors are accessed.

    摘要： In a preferred embodiment, an eletronic temperature gauge is carried into a well bore within a pressure-sealed housing which can free fall through a drill string to impact upon a drill bit connected at the bottom of the drill string. A shock absorber is connected at the bottom of the housing to absorb the shock upon impact of the apparatus on the drill bit. The shock absorber has a relatively linearized shock absorbing response in the preferred embodiment. Additional structural features provide further cushioning of the gauge during transit and upon impact.
