The evaluating reservoir pore structure quantitatively by using NMR log data has progressed rapidly in the last five years.It provides novel ideas and methods for geologists to sons the problems on exploration and development of complex reservoirs.In this paper,the latest developments of evaluating reservoir pore structure quantitatively by using NMR log data are reviewed.And the advantages and disadvantages and applicability of these methods are analyzed.Ant the same time,considering that all these methods are difficult in practical application,the future efforts of evaluating reservoir pore structure by using NMR log data should be focused on the methods of correlating theT_2 distribution when the pore space is occupied by hydrocarbon.
