Abstract

By using the acoustic travel time(AC) data

other test data and variable scale fractal techniques

the distribution of natural fractures in Chang 4+5

1-2

reservoirs of Yuan 48 wellblock in Tiebiancheng oilfield was predicted

and the relationship between the fracture development degree and initial deliverability of oil wells was also discussed.Based on the distribution characteristics of zones with relatively well-developed fractures and their formation conductivity

Chang 4+5

1-2

reservoirs are comprehensively classified and evaluated

and the results are in accord with the actual production data.The research results can be used for reference in the fracturedescription in low-permeability reservoirs.
