英文摘要	Low-temperature adsorption experiment, high-speed centrifugal gas displacing water experiment and nuclear magnetic resonance (nmr) experiment were conducted on sealed coring samples taken from triassic yanchang formation chang 7 tight oil reservoir of northern shaanxi area, odos basin, to analyze the tight oil occurrence space quantitatively. micro-capillary bound water t-2 (transversal relaxation time) spectra after 2.76 mpa centrifugation and distribution of micro-pores less than 50 nm obtained from low-temperature adsorption experiment both reflect less than 50 nm pore throats consistently, and conversion coefficient c of t-2 and pore radius can be computed from comparing their distribution. the conversion coefficient of 15 cores in the study area is 5.80 nm/ms on average. using c in oil phase t2 spectrum of sealed coring samples, the maximum pore radius of oil occurrence in the study area is 363-8 587 nm, 3 195 nm on average, and average pore radius of oil occurrence 50-316 nm, 166 nm on average, and main pore radius of oil occurrence is 97-535 nm, 288 nm on average. tight oil mainly exists in nanometer pores.
