| 摘 要： | 物质平衡法计算动态储量,它的准确性很大程度上取决于目前地层压力的准确获得。但是,在实际生产中,地层压力的测试数据很少,给应用者带来较大困难;同时,在应用二项式产能公式时,相关系数并非都是已知。另外,大量变形介质气藏的发现,也给其储量计算提出了更高要求。利用物质平衡方程与产能方程结合,充分利用生产井的产量和井底流压等动态数据,同时考虑变形介质影响的情况下,建立井底流压和产量同时拟合的多目标拟合函数,采用多目标遗传算法进行求解。这不但可以获得较准确的动态地质储量,而且可得到地层压力的变化趋势。该方法已经在实际应用中取得了较好的效果。

| Abstract: | The accuracy of calculating the dynamic reserves by material balance method depends on accurately acquiring the current reservoir pressure, but there is few pressure test data in actual production, which brings a lot of problems to users. At the same time, the correlation factor is not known when using the binomial deliverability equation. In addition, the calculation of reserves must be improved as a lot of deformation medium gas reservoirs are found. Combined with the equation of material balance and deli... |
