    摘要： A disclosed embodiment (Fig. 2) utilizes one or more toroidal coil antennas (205, 215) mounted, in an insulating medium (206), on a drill collar (202) to induce currents which travel in a path that includes the drill collar (202) and earth formations around the drill collar (202). At least one array of electrodes (A1-A20) is provided on at least one stabilizer blade (220A) of the drill collar (202) and is utilized to detect currents transmitted by toroidal coil antennas (205, 215) which return via the formations to the electrodes (A1-A20) laterally; that is, approximately normal to the axis of the drill collar (202). Signal traces are obtained from measurements taken at respective ones of the transducers, and a dip characteristic of the formations is determined from the signal traces and from signals representing the rotational orientation of the drill collar (202).

    摘要： The present invention relates generally to the use of polyaryletherketone-based thermoplastic materials in high pressure, high temperature, production logging applications. A polyaryletherketone resin bonded with glass fibers is formed into a housing for formation evaluation sensors permanently located downhole. The housing is constructed by any of the following processes: filament winding, fiber placement, or compression molding or injection molding. When used in a production well, the housing encloses the formation evaluation sensors and protects the sensors from borehole fluids. Housing properties can be modified with changes in materials added to the resin in order for the housing to function as casing or coiled tubing. This would allow wireline or logging-while-drilling conveyed sensors passing through the casing or coiled tubing to sense the formation and borehole fluid properties.

    摘要： Apparatus and method are disclosed for determining the resistivity of formations surrounding an earth borehole. An electrically conductive metal body (202), such an a drill collar on a drill string, is movable through the borehole. A transmitting toroidal coil antenna (205) is disposed on the body (202) and is energized to induce a current which travels in a path that includes the body (202) and the formations. An electrode (226,227,229,235) is disposed on the body, and a first signal which depends on the electrical effect of the current on the electrode is measured to obtain an indication of the resistivity of the formations. In a form of the invention, a second transmitting toroidal coil antenna (T2) establishes a second current in the body (202) that travels in a path that includes the body (202) and the formations, and a second signal is measured at the electrode (R). A current monitor measures the axial current passing a monitor position on the body, to obtain a monitor current value. A compensated indication of formation resistivity can then be obtained as a function of the first signal, the second signal, and the monitor current value. A local communication system facilitates the ultimate communication of information to the earth's surface.
