同时利用恢复压力和续流量进行试井分析的褶积法及应用讨论

CONVOLUTION AND ITS APPLICATION-TESTING ANALYSIS BY USING PRESSURE BUILDUP AND AFTERFLOW RATE SIMULTANEOUSLY

本文根据利用续流量测量数据进行试井分析的褶积理论,提出了适用于现场的分析程序。实例解释结果表明,褶积分析法能有效地解释早期压力恢复资料,且较霍纳法更为精确。本文还讨论了应用过程中出现的问题及对解释结果的影响。

<ABSTRACT>: Based on convolution theory which uses the data obtained from afterflow rate to do well testing analysis, this paper puts forward the analysis procedure that is suitable for fields. Example interpretation shows that convolution analysis method can effectively inter-pretate pressure buildup data of early period, and is more accurate than the Homer Method. This paper also discusses the problems occoured in application and its influence to the inter-pretation result.
