نویسندگان
چکیده
Rock grain size parameter is the key of reservoir rock physics analysis. The study found that relationship between NMR T 2 spectrum and distribution curve directly related to id="M2"> rock, so you can use id="M3"> retrieve spectral data. Based on calculation core experiment results by id="M4"> using conversion method piecewise nonlinear calibration for each core, adjusting parameters make calculated with analysis approximation, error minimum obtain scale conversion. In end, are classified according pore permeability. Finally, actual id="M5"> inversion underground granularity, contrast results, reliability verified provide accurate, continuous profile geological physics.

Field examples of the MRF Magnetic Resonance Flu...
متن کاملOn the effect of grain size on rock behavior under cyclic loading by distinct element method
It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...

متن کاملP63: Automatic Detection of Glioblastoma Multiforme Tumors Using Magnetic Resonance Spectroscopy Data Based on Neural Network
Inflammation has been closely related to various forms of brain tumors. However, there is little knowledge about the role of inflammation in glioma. Grade IV glioma is formerly termed glioblastoma multiform (GBM). GBM is responsible for over 13,000 deaths per year in the America. Magnetic resonance imaging (MRI) is the most commonly used diagnostic method for GBM tumors. Recently, use of the MR...
