摘　　要：对外加厚套管模拟井进行声幅/变密度、SBT测井实验和测井资料分析,归纳出声幅/变密度测井响应规律,同时对11口外加厚套管井进行试验和分析,总结出利用声幅/变密度综合评价外加厚套管固井质量的解释标准。利用全波分析技术等研究结果,编制了一套外加厚套管固井质量处理评价软件,最后利用该软件处理了17口外加厚套管井声幅/变密度测井资料,以其中1口为例进行了详细的分析,从而进一步验证了外加厚套管固井质量解释标准的可靠性及处理评价软件的合理性。Wells with external upset casing are analyzed with acoustic amplitude/variable density,SBT logging test and logging data.The law of acoustic amplitude/variable density response is summarized.Meanwhile,11 wells with external upset casing are tested and analyzed.The interpretation standard of cementation quality of such wells by using acoustic amplitude/variable density is established.Full-wave analysis technique is used to compile software of processing and evaluation for this purpose.This software has been used to process the acoustic amplitude/variable density data of 17 wells with external upset casing.One of these wells is analyzed in detail,and it is verified that this interpretation standard is reliable and the processing and interpretation software is rational.
