    摘要： A method for processing nuclear magnetic resonance (NMR) measurement data includes: receiving, with a processor, NMR measurement data obtained from an NMR tool, the NMR measurement data being affected by a motion artifact and having a first echo train obtained with a long polarization time TWET and a second echo train obtained with a short polarization time TWTL that is shorter than TWET; and at least one of (i) reducing, with a processor, an effect on the NMR measurement data of the motion artifact using the first echo train and the second echo train and (ii) identifying, with a processor, the motion artifact using the first echo train and the second echo train; wherein the motion artifact is related to a magnetic field magnitude that varies in a volume of interest due to a motion of the NMR tool.

    摘要： An apparatus for performing nuclear magnetic resonance (NMR) measurements of a material of interest includes an NMR tool and a processor. The NMR tool includes a transmitter antenna; a transmitter coupled to the transmitter antenna; and a receiver antenna configured to receive NMR signals in response to transmitted pulses of electromagnetic energy transmitted by the transmitter antenna. The NMR signals include at least a first signal and a second signal of a phase-alternated group of signals. The processor is configured to receive the NMR signals; receive a first system gain related to the first signal and a second system gain related to the second signal, each system gain being related to a system comprising the NMR tool and the material of interest; and calibrate the NMR signals using the first system gain and the second system gain.

    摘要： Apparatus, methods and computer programs disclosed herein, in one aspect, estimate a temperature of a selected region of an earth formation using a virgin formation temperature of the earth formation, a downhole fluid temperature measured over time, an elapsed time between drilling proximate the selected region and making of a formation evaluation measurement of the selected region, an estimate of thermal conductivity of the earth formation, and a heat capacity of the earth formation. In another aspect, the apparatus, methods and computer programs utilize the estimated temperature and the formation evaluation measurement to estimate a property of interest of the selected region.
