Abstract

In order to improve the accuracy of cementing quality evaluation for ultra-low density cement, a full-scale cementing quality evaluation model well group was constructed based on the real underground environment and the requirements for cementing quality and cement filling. A calibration method for cementing quality evaluation indicators was established, and the influence of factors such as logging time and cement density on cementing quality evaluation indicators was analyzed. The results were compared with theoretical calculations, The experimental results are in good agreement with the theoretical calculation results. According to the experimental results, the evaluation indicators of ultra-low density cement cementing quality are inversely correlated with cement density & logging time. The research results indicate that the accuracy and pertinence of cementing quality evaluation can be significantly improved by applying the ultra-low density cement slurry cementing quality evaluation model well group and verifying the ultra-low density cement cementing quality evaluation indicators.

超低密度水泥井组固井质量评价模型试验研究

为了提高超低密度水泥固井质量评价的准确性，根据井下实际环境和固井质量及水泥充填要求，构建了全尺寸固井质量评价模型井组。建立了固井质量评价指标的标定方法，分析了测井时间、水泥密度等因素对固井质量评价指标的影响。实验结果与理论计算结果进行了对比，实验结果与理论计算结果吻合较好。实验结果表明，超低密度水泥固井质量评价指标与水泥密度、测井时间成反比。研究结果表明，通过应用超低密度水泥浆固井质量评价模型井组和验证超低密度固井质量评价指标，可以显著提高固井质量评价的准确性和针对性。
