摘　　要：采用响应面法研究了关于堵漏材料在提高井筒内悬浮能力的优化设计。在研究最佳的堵漏材料类型时,需要选取堵漏材料的密度、几何平均轴径和不规则系数作为考察因素,以尽量降低堵漏材料的沉降时间为目标。采用Box-Benhnken分析方法进行3因素的3水平实验,考察3因素及交互作用对堵漏材料的沉降时间的影响。结果表明,计算结果符合二次方程。从统计学上看,二次模型是可靠的,充分反映了实验数据所得到的响应的变异性。此外,可以通过调节堵漏材料的几何平均轴径、密度和不规则系数调节堵漏材料的沉降时间。在堵漏材料的密度为1.2 g/cm^(3),几何平均轴径为12 mm,不规则系数为1时,得到最长的沉降时间为6.59 s。The optimal design of the plugging material to improve the suspension capacity in the wellbore is studied by using the response surface methodology.When researching the best type of leakage plugging material,it is necessary to select the density,geometric average shaft diameter and irregularity coeff icient of the leakage plugging material as the factors to be investigated,with the goal of reducing the settling time of the leakage plugging material as much as possible.The Box-Benhnken analysis method was used to conduct a three-factor three-level experiment to investigate the effects of the three factors and their interaction on the settlement time of the plugging material.The results show that the calculated results conform to the quadratic equation.Statistically,the quadratic model is reliable and fully reflects the variability in the responses obtained from the experimental data.In addition,the settling time of the lost circulation material can be adjusted by adjusting the geometric mean shaft diameter,density and irregularity coeff icient of the lost circulation material.When the density of the plugging material is 1.2 g/cm^(3),the geometric mean axial diameter is 12 mm,and the irregularity coeff icient is 1,the longest settling time is 6.59 s.
