| 摘 要： | 目前国内固井质量评价大量使用声波变密度测井资料,但声波变密度测井的首波声幅曲线仅可用来评价水泥环第一界面的胶结情况,而全波列变密度图像既能反映第一界面胶结情况,又能提供第二界面的胶结信息。对影响声波变密度测井资料评价的多种因素进行了详尽剖析后指出,在对固井质量解释时,应排除这些因素的影响,才能提高资料综合利用价值。

| Abstract: | It is popular to use CBL/VDL for cementing quality evaluation in China. The CBL curve could be use to evaluate the cementing of first interface, and the VDL could provide the information of both first and second interface. This paper illustrates the theory of cementing quality evaluation by CBL/VDL, and analyses all affecting factors, which may help to decrease the ambiguity of CBL/VDL interpretation and improve comprehensive utilization value of the logging data. |
