摘要： A first flux-loop inductive coupler element electrically couples with a second flux-loop inductive coupler element. The first flux-loop inductive coupler element comprises a first ring-like core having high magnetic permeability and a conical-section annular first face transverse to the plane of the first core. The first face has a first annular groove separating a first conical-section larger-diameter face and a first conical-section smaller-diameter face. A first coil is wound within the annular groove. The first and second cores form a low-reluctance closed magnetic path around the first coil and a second coil of the second flux-loop inductive coupler element.A first current-loop inductive coupler element electrically couples with a second current-loop inductive coupler element. The first current-loop inductive coupler element has a first high-conductivity, low-permeability shaped belt of a first end of a first pipe joint, a first ring-like core located at the first end, and a first electrically conductive coil wound about the first ring-like core. The first high-conductivity, low-permeability shaped belt partially encloses the first coil. It is shaped to cooperate with the second high-conductivity, low-permeability shaped belt of an adjacent second pipe joint having a second electrically conductive coil and a second high-conductivity, low-permeability shaped belt to create a closed toroidal electrical conducting path. The closed toroidal electrical conducting path encloses the first coil and the second coil when the first and second pipe joints are mated.

摘要： Measurement-while-drilling apparatus is disclosed for determining the resistivity of formations surrounding an earth borehole. An electrically conductive metal body, such as a drill collar on a drill string, is movable through the borehole. A transmitting toroidal coil antenna is disposed on the body and is energized to induce a current which travels in a path that includes the body and the formations. An electrode is disposed on the body, and an electrical signal resulting from said current is measured at the electrode to obtain an indication of the resistivity of the formations. In a disclosed embodiment, one or more electrodes can be mounted on a blade that is mechanically coupled to the body.

摘要： Sensors located in the vicinity of a hydrocarbon-producing well receive power and communicate with one or more hubs located in the well or at the outer surface of a casing by means of elastodynamic waves. Each hub incorporates a plurality of transducers which permit focusing of the emitted elastodynamic waves. In order to concentrate the energy on a single sensor, or a group of sensors arranged in a cluster. Hubs and sensors communicate by exchanging, modulated elastodynamic waves. Sensors belonging to a cluster may transmit, properly time-shifted elastodynamic waves, in order to collectively focus their energy in the direction of a hub. Time synchronization between the sensors within a cluster may be accomplished by means of electromagnetic fields which travel much faster than elastodynamic waves, but can only propagate over short distances in typical formations.
摘要翻译：位于产油井附近的传感器通过弹性动力波接收动力并与壳体中的井或外表面上的一个或多个轮毂连通。每个轮毂包括许多能够聚焦发射的弹性动力波的换能器。为了将能量集中在单个传感器或一组布置在集群中的传感器。轮毂和传感器通过交换，调制的弹性动力波进行通信。属于集群的传感器可以传输适当的时移弹性动力波，以便将它们的能量集中地集中在集线器的方向上。群集内的传感器之间的时间同步可以通过比弹性动力波快得多的电磁场来实现，但是只能在典型地层中的短距离上传播。
