Abstract: This paper makes a study of formation occurrence and fracture character of glutenite reservoir of Xiagou formation in Qingxioilfield using well log, mud logging and lab analysis data; a establishment of low limit standard of rock electrical property for the fracturedreservoir using dual laterolog,gamma ray log and tri-porosity logging data; a recognition of the vertical fracture-developed section andfractural occurence for it using dip log, fl-bore imaging microlog and dipole shear imaging sonic logging; finally, makes a developmentof interpretation model for parameters such as porosity, oil saturation, etc. using gamma ray log, dual laterolog data. It is believed thatthese studies provide reliable basis for evaluation of glutenite fractured reservoir in this area.
