固井质量评价影响因素分析

Analysis Of Influencing Factors Of Cementing Quality Evalutiom

固井质量评价是石油钻井中至关重要的一环,影响着井筒完整性、生产效率和环境安全。本文旨在探讨影响固井质量评价效果的关键因素。通过实验和测井资料分析,发现以下几个主要影响因素:仪器偏心、水泥凝侯时间、地层岩性、水泥密度和套管尺寸等。综合考虑这些因素,能够有效提高CBL/VDL评价固井质量的准确性和可靠性。

The evaluation of cementing quality is a crucial component in petroleum drilling,which affects wellbore integrity,production efficiency,and environmental safety.The aim of this paper is to explore the key factors affecting the effectiveness of cementing quality evaluation.Through experiments and well logging data analysis,several primary influencing factors were identified,including instrument eccentricity,cement curing time,formation lithology,cement density,and casing size.Taking into account these factors can effectively enhance the accuracy and reliability of Cement Bond Log(CBL)and Variable Density Log(VDL)evaluations for assessing cementing quality.
