Abstract
Summary
The nuclear magnetic resonance (NMR) transverse relaxation time (T2) distribution can be transferred into the capillary pressure curves by the method combined the J function with the NMR SDR model of permeability. The pore structure parameters are extracted through the constructed capillary pressure curves to establish the reservoir quality factor (QF) with NMR porosity and geometry average value of T2. The QF is applied to the classification of cores and tight oil reservoir. Results of the classification conform that the QF has a good performance in tight oil reservoir classification.
