Abstract: The H2 reservoir of Huoshaoshan oilfield in eastern Junggar basin is characterized by extremely low matrix permeability and relatively developed fractures. Over the years, the various data are taken for research and further fine description of the fractural features. Starting from the well log data, by means of R/S analysis, the fractures in H2 reservoir are studied. The R/S values of more than 300 wells are calculated one by one, by which the R/S curves of this reservoir are drawn. Also, the comparisons of these with real core sample, EMS, EMI fracture well logs as well as the production performances from producers and injectors are conducted. The results show a high degree of agreement, indicating fractal theory can be used for fractural analysis and study.

Key words: Junggar basin, Huoshaoshan oilfield, H2 reservoir, R/S analysis, fracture prediction
