| 摘 要： | 天然水驱油气藏的开发过程中, 无论储量计算还是动态预测, 都离不开无因次水侵量的计算。通常无因次水侵量的计算采用查表的方法, 既不实用, 精度又低。基于数理统计的原理, 评价了目前广泛应用的计算径向水驱无限大及有限系统天然水域van Everdingen-Hurst 无因次水侵量的经验公式方法, 进而提出了计算有限封闭天然水域无因次水侵量的新方法。

| Abstract: | The calculation of dimensionless water influx rate has to be made for both reserves estimation and performance prediction in process of development of natural water drive reservoirs. However, it is not practical and not precise to calculate the dimensionless water influx rate by available table-lookup method. Based on the theory of mathematical statistics, the widely applied empirical equation method of van Everdingen-Hurst dimensionless water influx rate calculation for infinite radial water drive and finite natural water domain is evaluated. And a new method for calculation of finite confining natural waters' dimensionless water influx rate is then proposed in this paper. |
