摘要： 基于底水锥进和低渗透非达西渗流原理,推导出了低渗透无隔板底水油藏油井见水时间的预报公式。通过鄂尔多斯盆地砂岩底水油藏某油井的实际计算,其预测见水时间与实际见水时间的相对误差仅为6.47%.

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
