摘要: 压力反褶积对原始地层压力非常敏感,且该参数精度必须控制在0.5% 以内,而通过Levitan 等方法来确定该参数时,不仅至少需要两个不同流动期数据,且易受压力流量非线性等诸多因素影响。提出的基于压力导数的反褶积模型不仅对原始地层压力值不敏感,而且可仅通过一个流动期来确定该参数值。通过分析,该模型可以处理压力误差,也可以处理流量误差

Abstract: The pressure deconvolution result is very sensitive to the initial reservoir pressure,and the error in this parameter
must be controlled within 0.5%. It requires at least two different flow periods to determine this parameter by Levitan’s method,
and it is very susceptible to such factors as nonlinearity in pressure and rate data. A new deconvolution algorithm based on
pressure derivative is presented,and it’s in sensitive to the initial reservoir pressure. Moreover,only one flow period can be
used to determine its value. Through detailed analysis in this paper,this algorithm can tolerate both errors in pressure and rate.
