摘要
以H N Mead提出、A R Hasan和C S Kabir推导建立的等轴双曲线方程为基础，提出了确定低渗透、特低渗透油藏生产井泄油范围内平均地层压力的简便方法。实例应用表明，该方法使用简便、结果可靠，特别适用于低渗透油藏生产时间很长的油井。
On the basis of the rectangular hyperbola equation proposed by H N Mead and established by A R Hasan and C S Kabir, this paper introduces a simple method for determining the average reservoir pressure within the oil drainage area of producing wells in low and ultralow permeable reservoirs. As shown by pratical applications, this method is easy to use and to give reliable results, which is especially applicable to long produced oil wells from low permeable reservoirs.
