Abstract

Abstract:

Viewed from conventional physical property and well logging response，there is similar reservoir characteristic between T1j21 & T1j22，they are all good reservoirs.NMR analysis of the cores from T1j22 indicates that there are big difference in pore structure in T1j21 & T1j22.Although there is higher porosity in T1j21，the poor spaces are taken up by irreducible fluids.The NMR data can be used to evaluate the reservoir effectiveness.To T1j21 ，the pore spaces are mainly taken up by mobile fluids，the throat radius method can be used to determine the limit of effective reservoirs，and it can be used as criteria to assess effective reservoirs.

Key words: reservoir characterization, pore structure, reservoir effectiveness, NMR, throat radius
