Analysis Of Influencing Factors Of Cementing Quality Evalutiom
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.
