受水侵影响,边底水活跃的水驱气藏在生产中后期会出现压力数据偏离直线段的现象,无法采用定容封闭气藏的压降法来计算动储量.针对此问题,提出将物质平衡原理与解析水域模型相结合的思路,采用最优化拟合法,计算水驱气藏动储量及水体大小.%Because of edge-bottom water invasion,the pressure data of water drive gas reservoir deviates from the straight line in the middle and late production, so the drop method cannot be used to calculate the dynamic re-serves. Combined the material balance equation with the model of analytical waters,the dynamic reserves and water body size of water drive can be quickly calculated by optimal fitting method.
