Abstract

Abstract:

The interlayer interference of extremely heterogeneous reservoirs becomes more serious as development.The layer series of development should be reconstructed.Reasonable selection is done for the permeability and the grading distribution of extremely heterogeneous reservoirs of Hu7 NanshaSanZhong on the basis of the dynamic and static reservoir data to design water displacing oil long core experiment for studying production pattern of different permeability cores.On the basis of experiment，production pattern of multilayers series of development is studied with the modified numerical simulator.An integrated contributory factor is presented to give fullscale reflection to the quantitative effect of heterogeneity on production characteristics and displacement effects of low permeability layers，and a reasonable technical limit is identified for combination of different permeable layers to give directions to practical development plan design of such extremely heterogeneous reservoirs.

Key words: heterogeneity, development layer, permeability grading, combination limit
