ABSTRACT: With the production of strong bottom water reservoir, it will soon enter
the ultra-high water cut stage. After entering the ultra-high water cut period,
the main means of stable production is liquid extraction. Large liquid volume
has a certain impact on the physical property distribution and fluid seepage
law of the oilfield. The relative permeability curve measured according to the
industry standard is not used for the prediction of development indicators and
the understanding of the dynamic law of the oilfield. In order to understand
the characteristics of water drive law in high water cut stage of water drive
oilfield, starting from the water drive characteristic curve in high water cut
stage, the method for calculating the relative permeability curve is deduced.
Through numerical simulation verification and fitting the actual production
data, it is confirmed that the obtained relative permeability curve is in line
with the reality of the oilfield, It can provide some guiding significance for
understanding the production law and water drive law of strong bottom water
reservoir in ultra-high water cut stage.
