中文摘要：

底水油藏水平井临界产量作为确定油井合理生产制度、延长无水采油期、提高水平井开发效果的重要参考依据,是控制油井过早见水的一个重要指标,准确计算其大小在底水油藏开发中至关重要。以底水油藏底水脊进机理为基础,借助底水油藏直井底水锥进渗流理论,考虑水平井筒周围椭球形等压面,利用椭圆流原理以及发展矩形族方法推导了底水油藏水平井临界产量计算新方法。通过实例计算与对比,新公式计算结果与修正Chaperon模型临界产量计算结果相对误差较小,说明新公式准确性较高,而Giger-Karcher模型、程林松-范子菲模型、窦宏恩模型由于假设条件与底水油藏实际渗流模式不符,最终导致临界产量计算结果偏差较大。敏感性分析表明临界产量随着油层厚度、井筒位置与油层厚度之比的增大而增大,而随着各向异性系数的增大而减小。
