Abstract

Abstract: Based on the principle of the bottom- water conning and low permeability non-Darcy flow, a formula for predicting water breakthrough time of oil-well in a low permeability bottom-water reservoir with no barrier is derived. It has been successfully applied in a low permeability bottom-water sandstone reservoir in Erdos basin. The relative error between the predicted and observed values is only 6.47%.

Key words: low permeability pools, bottom water reservoir, bottom water conning, oil well, prediction, water breakthrough time
