摘要： An apparatus and method for guarding the current injection sources of downhole logging tools utilized to determine the resistivity of an adjacent portion of a borehole wall. Two current electrodes are energized to create an oscillatory electric field in a borehole wall. The two current electrodes are each shielded with a conductive shield, maintained at the same electric potential as the current electrode, to prevent current leakage into the logging tool body. A current sensor is coupled between each current electrode and conductive shield to measure the actual current flow injected into the borehole wall from the current electrode and to compensate for current leakage. A voltage detector measures the differential voltage created by the electric field in the borehole wall, and the differential voltage is used in combination with the measured current flow to determine a resistivity value for the borehole wall.

摘要： Logging systems and methods that employ nanosensors to obtain spectral measurements downhole. The nanosensors can be dispersed in borehole fluids (including cement slurries) that circulate, diffuse, or get injected in a borehole. Because the nanosensors have diameters on the order of 10 nm to lOOOnm, they readily penetrate into cracks, pores, and other voids where their carrier fluids can reach. The nanosensors transport light sources and recording media to measure spectra in these otherwise inaccessible regions. The nanosensors are then recovered and analyzed to reconstruct the measured spectra, and determine relevant material characteristics. Among other things, spectral measurements can reveal the presence of certain elements and molecules in the formation and fluids, from which information scientists determine composition and phases of formation fluids and the formation itself. Certain triggering criteria may also be employed to enable the nanosensor measurements to be associated with specific locations, paths, and/or events.
摘要翻译：使用纳米传感器在井下获取光谱测量的测井系统和方法。纳米传感器可以分散在钻孔中的循环，扩散或注入的井眼流体（包括水泥浆）中。因为纳米传感器的直径在10nm到1000nm之间，所以它们很容易渗透到其载体流体可以达到的裂纹，孔隙和其它空隙中。纳米传感器传输光源和记录介质以测量这些其他不可接近区域的光谱。然后回收和分析纳米传感器以重建测量的光谱，并确定相关的材料特性。除了别的以外，光谱测量可以揭示地层和流体中某些元素和分子的存在，信息科学家可以从这些元素和分子确定地层流体的组成和阶段以及地层本身。还可以采用某些触发标准，以使纳米传感器测量与特定位置，路径和/或事件相关联。

摘要： Various systems and methods for performing optical analysis downhole with an interferogram (a light beam having frequency components with a time variation that identifies those frequency components. The interferogram is produced by introducing an interferometer into the light path, with the two arms of the interferometer having a propagation time difference that varies as a function of time. Before or after the interferometer, the light encounters a material to be analyzed, such as a fluid sample from the formation, a borehole fluid sample, a core sample, or a portion of the borehole wall. The spectral characteristics of the material are imprinted on the light beam and can be readily analyzed by processing electronics that perform a Fourier Transform to obtain the spectrum or that enable a comparison with one or more templates. An interferometer designed to perform well in the hostile environments downhole is expected to enable laboratory-quality measurements.

摘要： Various disclosed nuclear magnetic resonance (NMR) logging systems and methods employ an array of antennas to provide increased resolution without sacrificing signal-to-noise ratio. Certain method embodiments include: establishing a static magnetic field (BO) with a tool moving along a borehole through a formation; concurrently driving a multiple antenna cells to produce a radio frequency field (Bl) in said formation; measuring an individual response from each antenna cell as nuclear spins undergo precession in the formation; and determining at least one characteristic relaxation time of the formation based at least in part on the individual response. The individual responses can be associated with positions where the individual responses were measured, and the relaxation time can be determined from a combination of those responses associated with a given position. Certain responses may be excluded due to tool motion that degrades the measured response.

摘要： Various methods and tools optically analyze downhole fluid properties in situ. Some disclosed downhole optical radiometry tools include a tool body having a sample cell for fluid flow. A light beam passes through the sample cell and a spectral operation unit (SOU) such as a prism, filter, interferometer, or multivariate optical element (MOE). The resulting light provides a signal indicative of one or more properties of the fluid. A sensor configuration using electrically balanced thermopiles offers a high sensitivity over a wide temperature range. Further sensitivity is achieved by modulating the light beam and/or by providing a reference light beam that does not interact with the fluid flow. To provide a wide spectral range, some embodiments include multiple filaments in the light source, each filament having a different emission spectrum. Moreover, some embodiments include a second light source, sample cell, SOU, and detector to provide increased range, flexibility, and reliability.

摘要： Light sources are provided with enhanced low-frequency (e.g., near infrared) emission. Some disclosed embodiments include a filament and at least one re-radiator element. The filament heats the re-radiator element to a steady-state temperature that is at least one quarter of the filament's absolute temperature. As disclosed herein, the increased surface area provided by the re-radiator element provides enhanced IR radiation from the light source. Patterning or texturing of the surface can further increase the re-radiator element's surface area. Various shapes such as disks, collars, tubes are illustrated and can be combined to customize the spectral emission profile of the light source. Some specific embodiments employ a coating on the bulb as the re- radiator element. The coating can be positioned to occlude light from the filament or to augment light from the filament, depending on the particular application. The various re- radiator elements can be positioned inside or outside the bulb.
