摘要： A pseudo-image is produced by combining deep-reading azimuthally sensitive resistivity measurements with azimuthally insensitive resistivity measurements made by a multiple propagation resistivity tool. This image is useful in reservoir navigation. Features on the azimuthally sensitive measurements such as saddle-points and mid-points are diagnostic of bed geometry relative to the borehole.

摘要： A borehole tool for logging resistivity of geologic formations, having at least two inner transmitters surrounded by at least two outer receivers. Each transmitter is sequentially excited, and measurements are taken at each of the receivers. The phase differences between these received signals are determined, once for each transmitter, and the two values are averaged to estimate the resistivity value of the surrounding formations. More than two receivers can be used. An azimuthal receiver array is also used to identify boundary transitions.

摘要： The present disclosure provides a downhole tool that includes a magnetometer and a nuclear magnetic resonance (NMR) sensor. One or more compensating magnets are provided on the tool to cancel or offset the effect of the magnetic field of the magnets of the NMR sensor on the magnetometer measurements made during drilling of a wellbore. The compensating magnets may have the same magnetic field characteristics as the sensor magnets and may be made of the same material.

摘要： A dual resistivity and induction apparatus for the investigation of earth formations traversed by a borehole, comprises an electrode system, supported on a support member, comprising a central electrode and five pairs of electrodes respectively short-circuited and aligned symmetrically about the central electrode at increasing distances therefrom; the central electrode and the electrodes of the fourth and fifth pairs are called current electrodes, the electrodes of the first, second and third pairs are called voltage electrodes; a source of alternating current at a first frequency, f.sub.1, is coupled between the electrodes of the fifth and fourth pairs; a source of alternating current at a second frequency, f.sub.2, is coupled between the electrodes of the fifth pair and an electrode at electrical infinity with respect to the electrode system; a circuit arrangement coupled to the electrodes of the fourth pair for generating current at f.sub.1 from the central electrode for maintaining the potential difference between the first and second pairs of electrodes at substantially zero and for generating current at f.sub.2 from the central electrode for maintaining the potential difference between the first and third pairs of electrodes at substantially zero; first and second impedances, respectively interposed between each of the source of alternating current and the current generating circuit and the fourth pair of current electrodes; and transmitter and receiver coils supported on the support member, for inducing at a third frequency, f.sub.3, electromagnetic energy; the length, along the axis of the support member, of each of the electrodes of the fifth pair is several orders of magnitude smaller than the relative spacing along the support member of that fifth pair of electrodes to reduce the interference between the electrode system and the coil system.

摘要： The invention is a method and apparatus for determining an electrical property a formation surrounding a borehole with a measuring-while-drilling device. The apparatus an antenna configuration disposed along the outer face of an extendable stabilizer joined to a rotatable drill collar. Typically, two receivers and two transmitters are spaced along the longitudinal axis of the drill collar, with the two receivers spaced symmetrically in between the two transmitters. Alternatively, receivers and transmitters can be spaced along the circumference, possibly over multiple stabilizers. Multiple assemblies can be used. Data can be obtained with the transmitter-receiver assembly held in a stationary position or rotating circumferentially. Apparatus can be operated in a “broadside” configuration, an “endfire” configuration, or a configuration in which transmitter coils and receiver coils are oriented orthogonally to each other.

摘要： A resistivity logging apparatus has an array of electrodes projecting from imaging pads. The electrodes penetrate nonconductive mud lining the borehole wall. Some of the electrodes are moveable in and out of the pad while others of the electrodes can be fixed. The electrodes, which are arranged in an array along a circumferential portion of the borehole wall, are able to make contact with the borehole wall. Sequencing electronics causes one electrode to be a source, another to be a measuring electrode, with the measurements of source electrode and measuring electrode moving along the array in order to log a circumferential portion of the borehole wall.

摘要： A system for communicating between a first location and a second location comprises a jointed tubular string having a first section and a second section connected at a connection joint, with the tubular string having a fluid in an internal passage thereof. A first acoustic transducer is mounted in the internal passage of the first section proximate the connection joint, and a second acoustic transducer is mounted in the internal passage of the second section proximate the connection joint. A signal transmitted from the first location to the second location is transmitted across the connection joint as an acoustic signal in the fluid from the first acoustic transducer to the second acoustic transducer.
