Abstract

Gasikule oilfield E¹₃ reservior belongs to low permeability reservoir and is hard to be developed due to strong heterogeneities.Every oil layer has its own ultimate production-injection well spacing due to the existence of starting pressure gradient and different properties.Determination of rational production-injection well spacing is significant for economic and effective exploitation.This paper established the relationship between degree of water flooding reserves and production-injection well spacing considering vertical heterogeneity of the E¹₃ reservoir,analyzing the controlling factors effecting degree of water flooding reserves,putting forward the method of determination rational production-injection well spacing. 

Key words： Heterogeneity low permeability reservoir; Starting pressure gradient; Production-injection well spacing; Degree of water flooding reserves
