摘要： 基于Seetharam和Jones修正的Horner方程, 建立了一种压力恢复曲线早期段解释的新方法。试井模拟及现场实际应用的结果表明, 该法处理续流段资料和计算地层参数的结果与典型曲线拟合及Horner等方法计算压力恢复中期段数据得到的结果基本一致, 同时该方法较典型曲线拟合法更为简便。

Abstract: Upon the revised Horner equation by Seetharam and Jenes. a new method for the early stage interpretation of pressure build-up curve was developed. The results of well test modeling and field application indicated that the results of processing afterflow data and caculating formation parameters by means of this new method are gene-ally identical with the ones of estimating middle stage data of build-up pressure using rype-curve match and Horner's method. Furthermore, this new method is simpler than the type-curve match.
