Abstract: By using resin thin-section, the characteristics of secondary pore sys-tem
in HE-3 member of sandstone are observed in Shuanghe oil field.
Four porosityareas and nine types of pore networks are divided, and
capillary pressure curves and pore structure parameters of corresponding
samples are given out in this paper.On this basis, visually-estimated
recovery factors of all kinds of pore networks are presented.And it is
found that the oil recovery factor of HE- 3 member in Shuanghe oilfield
is 40.5%，which is calculated by the weighted average method,

Key words: pore networks types, resovery factor, secondary pores
