Water Flooding Curve in Determining the A reservoir Water Flood Sweep Efficiency

摘要

A reservoir in the Jurassic natural water drive development of sandstone reservoirs, reservoir rock sandstone and siltstone and fine particle size, carbonatites cement content less, does not affect the reservoir properties. A reservoir average porosity of 18% and average permeability of 45×10~(-3)μm~2, belongs in porosity and low permeability reservoir, and the reservoir was not continuous development, strong heterogeneity. A reservoir development characteristics, application of water flooding curve and the related empirical formula A reservoir water flooding sweep efficiency.
