摘　　要：正确的评价固井质量,可避免不必要的封窜和挤水泥作业,对降低勘探开发费用有着十分重要的意义。本文针对快速地层固井质量评价中存在的问题,从理论研究出发,系统数值模拟了快速地层中各种胶结状况波形与固井质量的关系,提出了快速地层情况下资料信息提取和固井质量评价的方法,最后建立了快速地层固井质量评价系统。On the basis of evaluating the cementingquality correctly, such unnecessary work as cement squeezing can be avoided, good cementing quality is beneficial to decrease the exploratory development expense. There are some difficulties in cementing quality evaluation of fast formation. In this paper, after theory analysis, we firstly study the relation between various wave models and the cementing states about fast formation by numerical simulation. Secondly, we study the method of extraction data and cementing quality evaluation under various cementing state. At last we develop the software of cementing quality evaluation about fast formation.
