| 中文摘要:根据不同模糊数学隶属函数分布曲线的形状和走向，分别选取适合描述水泥浆稠化时间、流性指数、API滤失量、抗压强度和析水性能的模糊分布，以实际固井的水泥浆实测性能综合评分与实际固井质量评分对比，优选了相关隶属函数的参数。以5口井的实际固井为例，验证了评价方法的可靠性，所得到的评价结果与现场固井胶结质量的平均拟合误差由文献\[4\]中的±12.26%减小到±3.34%。证明本研究所确定的评价方法可作为水泥浆体系及外加剂的优选方法，合理确定固井质量。 |

| Abstract:Based on the shape and direction of different fuzzy membership function's distributional curve, we selected the fuzzy distribution which is suitable to describe the cement slurry’s thickening time, liquidity index, API fluid loss, compressive strength. By comparing the actual performance of cement slurry designed and measured with actual cementing quality score, we got the parameters of related membership function . Taking the 5 wells as an example, the results obtained from this evaluation method are verified by existing literature and the average fitting error of the cementing quality of the site is raised to -3.34% by -12.26%, which means this method can be used as a practical and reliable method for optimization of cement slurry system and admixture. |
