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+521-2 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+521-2 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.

Key words: acoustic travel time, natural fracture, variable scale fractal technique, reservoir classification
