摘要： An electromagnetic antenna for Measurement-While-Drilling (MWD) applications is disclosed. The antenna can include several array elements that can act alone or together in various measurement modes. The antenna elements can be disposed in tool body recesses to be protected from damage. The antenna elements can include a ferrite plate crossed or looped by independent current carrying conductors in two or more directions forming a bi-directional or crossed magnetic dipole. Although disclosed as a MWD system conveyed by a drill string, basic concepts of the system are applicable to other types of borehole conveyance.

摘要： The present invention provides a nuclear magnetic resonance ("NMR") tool for determining geological properties of formations surrounding a borehole when said tool is traversed in the borehole. One embodiment of the NMR tool includes at least one permanent magnet that is disposed substantially parallel to a longitudinal axis of the tool to generate a static magnetic field at a known distance in the formation. Radio frequency magnetic field in the zone of interest is generated by passing current at a radio frequency through a linear electrical conduction path along the longitudinal axis of the tool. The frequency may be swept during operation of the tool. The return path for the RF current is through the formation. A receiver detects signals from the formation responsive to the induced radio frequency magnetic field, which are processed to provide information about a formation parameter such as the formation porosity, hydrocarbon saturation and permeability of the zone of interest. A plurality of symmetrically arranged permanent magnets may be utilized instead of a single permanent magnet. An alternative embodiment utilizes a plurality of permanent magnets to produce a static magnetic field that is substantially radial in the zone of interest.
摘要翻译：本发明提供了一种核磁共振（“NMR”）工具，用于当所述工具在钻孔中穿过时确定钻孔周围的地层的地质特性。 NMR工具的一个实施例包括至少一个永磁体，该永磁体基本上平行于工具的纵向轴线设置，以在地层中以已知距离产生静态磁场。感兴趣区域中的射频磁场是通过沿着工具的纵向轴线的线性导电路径的射频通过来产生的。在工具运行期间，频率可能会被扫过。 RF电流的返回路径是通过形成。接收机响应于感应的射频磁场检测来自地层的信号，其被处理以提供关于地层参数的信息，例如地层孔隙度，烃饱和度和感兴趣区域的渗透率。可以使用多个对称布置的永磁体代替单个永磁体。替代实施例利用多个永磁体来产生在感兴趣区域中基本上是径向的静态磁场。

摘要： A steerable, magnetic dipole antenna for Measurement-While-Drilling (MWD) or Logging-While-Drilling (LWD) applications. The antenna elements use a hole arrangement in addition to grooves in a steel tool body, which is typically a drill collar. This antenna embodiment is extremely robust, meaning that does not significantly reduce the structural integrity of the tool body in which it is disposed. The antenna embodiment is also relatively wear resistant. The resultant magnetic dipole generated by this antenna is also electrically steerable in inclination angle from a common origin. A variable dipole moment inclination angle combined with independently measured tool rotation orientation during normal drilling allows the antenna to generate a magnetic dipole moment that may be directed at any three dimensional angle and from a common origin point at the centroid of the antenna. The antenna can also be embodied to be more sensitive to resitivity in a particular azimuthal direction.

摘要： A method for detecting and sensing boundaries between strata in a formation during directional drilling so that the drilling operation can be adjusted to maintain the drillstring within a selected stratum is presented. The method comprises the initial drilling of an offset well from which resistivity of the formation with depth is determined. This resistivity information is then modeled to provide a modeled log indicative of the response of a resistivity tool within a selected stratum in a substantially horizontal direction. A directional (e.g., horizontal) well is thereafter drilled wherein resistivity is logged in real time and compared to that of the modeled horizontal resistivity to determine the location of the drill string and thereby the borehole in the substantially horizontal stratum. From this, the direction of drilling can be corrected or adjusted so that the borehole is maintained within the desired stratum.
