摘要： A compact magnetic sensor is described that is capable of use in pad-mounted applications and field-focusing applications. A downhole induction tool is described with a compact induction sensor having electromagnetic transmitters wound on a longitudinal core member of a C-clamp shaped transmitter core. The downhole induction tool is suitable for transmitting magnetic excitation fields in multiple directions, both parallel and transverse to the downhole induction tool's longitudinal axis, with minimal susceptibility to errors associated with parasitic eddy currents induced in the metal components surrounding the transmitter and receiver coils. The horizontal (transverse) members of the C-clamp shaped transmitter core can be rotated to orient a magnetic excitation flux path passing between the horizontal (transverse) members and through a downhole formation. The horizontal members can be replicated on a single longitudinal member to shape the magnetic excitation flux path.

摘要： A well logging instrument string including a first section adapted to be operated substantially in contact with a wall of a wellbore, a coupling connected at one end to one end of the first section. The coupling includes first and second flexible joints for enabling relative angular deflection between the first section and a second section. The coupling includes a biasing mechanism for urging at least one of either the first or the second flexible joints, or both, to assume their positions of maximum angular deflection. The instrument string includes a second section connected to the other end of the coupling. The second section is adapted to be operated spaced apart from the wellbore wall.

摘要： For use in a downhole oil well logging tool which is enclosed in a sonde and suspended on an armored logging cable, a means for measuring the macroscopic thermal neutron capture cross section of the borehole fluid is set forth. In the preferred embodiment, a neutron source adjacent to a neutron detector is positioned in a sonde. The entire surrounding region in the well borehole is used as a sample chamber. Fast neutrons from the source after collision with fluid nuclei impinge on the detector which provides an output signal which is indicative of neutron flux. The count rate is most significantly dependent on the thermal neutron capture cross section of the borehole fluid. An additional detector can likewise be spaced farther from the neutron source and provide an alternate count rate. Through the use of two detectors, minor perturbations induced by changes in the environment outside the borehole can be compensated. The neutron capture cross section can be determined for the borehole fluid. Preferably, the sonde is supported for traveling along a cased well on centralizers to control the volume of fluid that is in the immediate vicinity of the neutron source which fluid may be characterized as falling within a test chamber region defined by the case 12.
