摘　　要：目前常用的页岩气单井动用储量计算方法为流动物质平衡法、Ibrahim法和Anderson法等。但上述方法采用试算法求解储量,手动调参,过程繁杂,计算难度大。为了合理评价页岩气动用储量,引入列队竞争算法对页岩气进行储量优化计算,以最小损失误差为目标函数、以储量上下限为约束条件,建立页岩气动用储量优化模型。在误差许可的范围内,通过模型自动拟合出合理的单井动用储量。计算结果显示,流动物质平衡法、Ibrahim法和Anderson法计算结果的相对误差较小。由此可见,页岩气动用储量优化模型的精度满足应用需求,同时降低储量计算的操作难度,为页岩气储量计算提供了一种新的程序化方法。At present, the commonly used methods for calculating shale gas single well production reserves are flowing material balance method, Ibrahim method and Anderson method. However, these methods use trial algorithm to solve the reserves and manually adjust parameters, which is complicated and difficult to calculate. In order to reasonably evaluate the shale gas production reserves, the queued competition algorithm was introduced to calculate the shale gas production reserves, taking the minimum loss error as the objective function, the reserve upper and lower limits as the constraint conditions, the shale gas production reserves optimization model was established. Within the error tolerance range, the model was used to automatically fit the reasonable single well operating reserves. The calculation results showed that the relative errors of the flow material balance method, Ibrahim method and Anderson method were small. It can be seen that the precision of the shale gas production reserve optimization model can meet the application demand and reduce the operational difficulty of the reserve calculation, providing a new programmed method for the shale gas reserve calculation.
