Abstract:

Central Junggar basin is rich in petroleum resources,much of which are accumulated in subtle oil/gas reservoirs. The subtle oil/gas reservoirs are characterized by control of multiple sedimentary systems, structural lithologic combination, multiple oil-bearing layers and multi stage reservioring. Both new ideas and relatively mature methods should be used in exploration of subtle oil/gas reservoirs. Firstly, determining favorable horizons for development of subtle traps through high resolution sequence stratigraphic division and correlation; then looking for slope break zones and favorable facies zones through palaeotopographic and sedimentary environment studies; and finally locating subtle traps and searching for subtle reservoirs through seismic processing.

Key words: Junggar basin, subtle trap, depositional system, reservoiring characteristics, high resolution, slope break belt
