摘要： In a method and apparatus for interventional imaging in magnetic resonance tomography, a contrast agent liquid is prepared by saturation or excitation of the nuclear spins therein, such that it shows with a poor signal in the vessel system of a patient to be examined after injection, or the stationary tissue is prepared by saturation or excitation of the nuclear spins therein such that the contrast agent liquid shows with strong signal (compared to the tissue) in the vessel system of a patient to be examined after injection.

摘要： The present invention provides methods and apparatus for determining flow velocity within a formation utilizing nuclear magnetic resonance (NMR) techniques in which the shape of the resonance region is restricted so that sensitivity to radial flow or vertical flow is obtained (or both when more than one NMR tool is used). Flow velocity using these NMR tools is determined using decay amplitude, frequency displacement or stimulated echoes (where the spins are stored along the magnetic field instead of the transverse plane to exploit echo decays and frequency displacements) based on the application of adiabatic pulses. Based on the described NMR measurement of flow velocity, additional wellbore parameters may be obtained such as a direct measurement of permeability, an assessment of drilling damage to the wellbore, formation pressure, invasion rate of the mud filtrate or the migration of fine mud particles during sampling operations.
摘要翻译：本发明提供了使用核磁共振（NMR）技术确定地层内流速的方法和装置，其中共振区域的形状受到限制，以便获得对径向流动或垂直流动的敏感性（或者当多于一个使用NMR工具）。基于绝热脉冲的应用，使用衰减幅度，频率位移或受激回波（其中旋转沿着磁场而不是横向平面存储以利用回波衰减和频率位移）来确定使用这些NMR工具的流速。基于所描述的流速的NMR测量，可以获得额外的井眼参数，例如直接测量渗透率，评估钻井对井眼的破坏，地层压力，泥浆滤液的侵入速率或细泥浆颗粒的迁移采样作业。

摘要： The present invention relates generally to a nuclear magnetic resonance apparatus and method for substantially eliminating the effects of phase coherent acoustic ringing in borehole logging. A series of cycles of measurement pulse sequences are applied to the formation surrounding the borehole. Each pulse sequence includes an RF excitation pulse and several RF refocusing pulses. Spin echoes are received that contain spurious ringing signals from the excitation and refocusing pulses. Spin echo signals from corresponding spin echoes of each cycle are combined and substantially cancel the spurious ringing from the excitation and refocusing pulses of the pulse sequences.

摘要： The present invention relates generally to an apparatus and method for obtaining an azimuthally resolved nuclear magnetic resonance measurement of an earth formation traversed by a borehole. The measurement can be made while drilling or using a wireline tool. A receiving rf antenna having a non-axisymmetric response pattern is used to obtain the azimuthally resolved nuclear magnetic resonance measurement. The antenna employs axial currents which excite an azimuthally oriented rf magnetic field. For this situation, the static magnetic field is either radial or axial in its orientation. The antenna generates a relatively long, in axial extent, region of generally uniform static field magnitude and polarization in the formation. The present invention facilitates low profile antenna configurations that can permit dispensing with the reduction of the inner diameter of the drill collar at the rf antenna location.
