摘要
Abstract
Turpan-Hami oilfield is characterized by low porosity, low permeability and low salinity. When the formation water saturation is greater than 50%, reservoir resistivity increases with the rise of formation water saturation. The indoor core water injection displacement experiments show that resistivity decreases with the increase of formation water saturation when injection water salinity equals to raw formation water salinity. When injection water salinity is lower than formation water salinity, resistivity curve shows "U" shape when the water saturation increases, rather than monotonically decreasing. Established is the saturation calculation model for water-flooded layer. Formation water saturation and oil saturation for cased hole can be calculated through multiple iterative computations based on through casing formation resistivity. Optimalizing water saturation may be figured out by following steps: determining water flooding stage through comprehensive analysis; determining the mixed water resistivity; using "U" shape curve iteration method to compute water saturation combining with Archie equation.关键词
