Abstract:

Shuanghe Oilfield is a typical “small and fat” oil field with great oil abundance in China. However, as a big oil field, it was found that mostly traps have not been filled with oil and gas. Further more，oil-gas filling degrees of different traps showgreat differences in the oil field. The result of research shows that the difference has great relationship between reservoir permeability grade differential and dominant channel, that is, the process of the oil and gas filling is controlled by channel seepage flowcapacity and the oil group’s grade difference of reservoir.

Key words: complicated structure, compacted rock, rockmechanic, simulated formation condition, water saturated/oil saturated
