摘要： In one aspect of the invention, a downhole sensor system comprises at least one downhole sensor disposed on or within a downhole component of a tool string. The downhole sensor is adapted to detect at least one characteristic of a downhole formation adjacent the downhole component. The downhole sensor has a variable sampling rate controlled by a processing element. The processing element is in electrical communication with a tool string rate-of-penetration sensor and/or a tool string rotational speed sensor. The processing element is adapted to vary the sampling rate in response to the rate-of-penetration and/or rotational speed of the tool string. In some embodiments, the system is a closed loop system.

摘要： A downhole induction resistivity assembly that comprises a downhole tool string component. The tool string component comprises an induction transmitter. The transmitter is adapted to induce an induction field in the surrounding formation. A first induction receiver is spaced apart from the transmitter and is adapted to measure the induction field. A magnetic field generating mechanism is disposed adjacent on either or both sides of the transmitter and adapted to guide the transmitter's signal into the formation. A second induction receiver is disposed in close proximity to the magnetic field generating mechanism and is adapted to measure the magnetic field generated by the mechanism.

摘要： In one aspect of the present invention, an induction resistivity tool includes an induction transmitter and an induction receiver located along the length of the tool. The transmitter is located adjacent at least one induction bucking coils of the tool. When activated the bucking coils are configured to direct a field transmitted by the induction transmitter away from the tool at an angle from the central axis of the tool.
