摘要： The present invention provides an apparatus and method for increasing the spatial resolution of data obtained by a measuring system using dynamic magnetic fields transmitted into and induced out of a subsurface geological formation. When a primary electromagnetic transmission field is directed at the formation, a steady state magnetic field is achieved. After a steady state magnetic field is established, current is discontinued, and an electrical response is induced from the formation after the primary field changes its magnetic state. The apparatus of the invention is essentially comprised of an induction type transmitter-receiver equipped with an energy-guiding member such as a non-conductive DC magnetic focusing assembly. By imposing a shaped magnetic field over transient currents induced in the formation, the rate at which the transient currents radially diffuse is reduced, and an increase in the axial beam length of the induced current density is realized. Since the current density is axially increased over a longer distance than would otherwise be possible in an arrangement lacking an energy-guiding member, greater vertical and azimuthal resolution of discontinuities in the formation's homogeneity are achieved.
摘要翻译：本发明提供一种用于增加通过使用传输到地下地质构造中并从地下地质构造中引出的动态磁场的测量系统获得的数据的空间分辨率的装置和方法。当主电磁传播场指向地层时，实现了稳态磁场。在稳态磁场建立后，中断电流，并且在主磁场改变其磁状态之后，从地层引起电响应。本发明的设备基本上由配备有诸如非导电DC磁聚焦组件的能量引导构件的感应型发射器 - 接收器组成。通过在地层中感应出的瞬态电流施加成形的磁场，瞬态电流径向扩散的速率减小，并且实现感应电流密度的轴向光束长度的增加。由于电流密度在比缺少能量引导构件的布置中可能的情况下更长的距离上轴向增加，因此实现了地层中的不连续性的更大的垂直和方位分辨率的均匀性。

摘要： The electromagnetic acoustic transducer (EMAT) transducer disclosed herein is useful for the non-destructive analysis of objects. The transducer comprises a core having a winding and a coil disposed between the core and the object to be analyzed. One transducer can be used as a transmitter and another transducer as a receiver. Then selectively switching static magnetic field in either transmitter or receiver and processing data with and without static magnetic Held allows for eliminating artifacts due to parasitic coupling between the transmitter/receiver pair. The switching of the static magnetic field can be implemented either by using electromagnet or a pair of permanent magnets where magnetization of one permanent magnet is reversed to provide cancellation of the static magnetic field.
