摘　　要：介绍并分析了目前固井质量评价中存在的主要问题,探讨了客观评价固井质量的方法。目前国内大部分油田采用声幅测井(CBL)评价固井质量,虽然声波/变密度测井(VDL)技术也正在作为基本的固井评价手段加以推广和应用,但是仍显不足,比如受微环隙、快速地层等因素的影响,测井资料易出现多解,常造成对固井质量的误判。本文着重针对以上两个因素的影响,介绍了应用多种测井方法组合的综合评价方法,并通过实例证明,得到了较好的效果。This paper introduces and analyzes the existing problems in cementing quality evaluation, discusses how to evaluate cementing quality truly. At present, most oil fields use the CBL to evaluate cementing quality, though the VDL has already been applyed as a basic method to evaluate the cementing quality, the effect can： not satisfy all conditions. For instance, the effect is influenced by micro--annulus. high--velocity （fast） layer, etc. We often get multi--solutions and mistakenresuhs. Aim at these two main problems, this paper introduces comprehensive evaluating method which is composed of several well logging methods. We can get good effect from actual instance.
