摘要： Systems and methods for generating a multi-dimensional distribution function. First data and second data may be received in response to one or more radiofrequency pulses that are transmitted into a subterranean formation. The first data may include Carr-Purcell-Meiboom-Gill data, and the second data may include diffusion editing data with initial echo spacings longer than subsequent echo spacings. The second data may be inverted. A multi-dimensional distribution function may be determined using the inverted second data.

摘要： A coaxial nuclear magnetic resonance (NMR) probe and related methods are described herein. The coaxial NMR probe includes a housing with a fluid inlet, a fluid outlet, a longitudinal axis, and an interior volume. The housing contains a fluid sample that is analyzed by the probe. The coaxial NMR probe also includes an elongated conductor disposed along the longitudinal axis of the housing. The elongated conductor generates an oscillating electromagnetic field within the interior volume of the housing. The oscillating electromagnetic field produces a NMR signal within the fluid sample. The elongated conductor may also be used to receive this NMR signal. The NMR signal is then analyzed to determine information about the fluid sample. Various NMR pulse sequences for use with this coaxial probe and other coaxial probes are also described herein.

摘要： Methods and systems are provided for tools having non-resonant circuits for analyzing a formation and/or a sample. For example, nuclear magnetic resonance and resistivity tools can make use of a non-resonant excitation coil and/or a detection coil. These coils can achieve desired frequencies by the use of switches, thereby removing the requirement of tuning circuits that are typical in conventional tools.

摘要： In one aspect, a nuclear magnetic resonance (NMR) system includes a transmitter to output a main refocusing pulse sequence and at least one subsequent refocusing pulse sequence into a zone of interest, a randomizing pulse module to output a randomizing pulse into the zone of interest to remove a net detected residual magnetization, and a receiver to output an NMR data set from the zone of interest. In another aspect, a method of generating a nuclear magnetic resonance (NMR) data set includes outputting a main refocusing pulse sequence and at least one subsequent refocusing pulse sequence into a zone of interest, outputting a randomizing pulse from a randomizing pulse module into the zone of interest to remove a net detected residual magnetization, and sensing the NMR data set from the zone of interest.

摘要： A system for drilling a borehole is disclosed. The system may include drill string having a bottom hole assembly a nuclear magnetic resonance tool within the bottom hole assembly, and a surface control system including a nuclear magnetic resonance measurement quality map. The control system may be configured to drill a borehole at a first set of drilling parameters and to receive motion properties from the nuclear magnetic resonance tool and adjust the drilling of the bore hole at a second set of drilling parameters. The surface control system may be further configured to adjust the drilling of the bore hole based on the motion properties from the nuclear magnetic resonance tool and the nuclear magnetic resonance measurement quality map.

摘要： A method for measuring one or more properties of a formation includes applying a magnetic field to a subterranean formation using a downhole tool. A radiofrequency signal is transmitted into the subterranean formation that is exposed to the magnetic field. The radiofrequency signal induces a transverse magnetization in the subterranean formation, and the transverse magnetization induces an initial voltage signal in the downhole tool. The initial voltage signal is amplified using a first amplifier in the downhole tool such that the first amplifier outputs a first amplified voltage signal. The first amplified voltage signal is introduced to an input of the first amplifier, such that the first amplifier amplifies the first amplified voltage signal and outputs a second amplified voltage signal

摘要： A nuclear magnetic resonance (NMR) system includes a transmitter of an NMR tool to output a magnetic field pulse into a zone of interest, a receiver of the NMR tool to output an NMR echo data set produced from an interaction of the magnetic field pulse and the zone of interest, and an NMR echo processing module including a filter matched to a response of the NMR tool to output a filtered NMR echo data set from the NMR echo data set, wherein the filter is matched to an echo shape of the NMR echo data, is matched to an average of a selected signal spectra of the NMR echo data set, or dynamically changes in response to a measurement.
