“串珠”状地震反射与试井分析“串珠"模型关系探讨

Discuss on Relationship between“Beaded " Seismic Reflection and“Beaded" Model at Well Test Analysis

在缝洞型碳酸盐岩储层中,有效储集体的地震反射具有"串珠、杂乱、片状和弱反射"等四种不同的响应特征,其中"串珠"反射为最优质反射类型。通过对"串珠"反射响应的储集体进行压力恢复测试发现,"串珠"反射状储集体具有不同的渗流特征,试井分析中的"串珠"模型仅为"串珠"反射中的一种特殊类型。

In the crack and hole carbonate reservoirs,seismic reflection for effective reservoir has the four different reflection response characteristics,that are the beads,mixed and disorderly,flake and weak reflection,and the beaded reflection among those is the best quality type. Through pressure buildup test to reservoir with the beaded reflection response,it is found that reservoir having＂beaded ＂ reflection has different seepage characteristics,and the ＂beaded＂ model at well test analysis is only a special one.
