摘　　要：砾石充填防砂已成为目前主要的防砂技术,包括套管中的砾石充填,高压砾石充填和人工井壁覆盖层控制方法。砾石尺寸、砂比和泵排量等参数的设计是影响该防砂技术成败的主要因素。通过砾石层孔喉结构的计算机模拟,利用孔喉结构分布曲线和地层砂粒度分布曲线优化砾石尺寸。渤海油田一口油井采用高压砾石充填设计,防砂效果良好。gravel pack sand control has become the main sand control technology,including casing gravel pack,high-pressure gravel pack and artificial well wall control method.The design of parameters such as gravel size,sand ratio,and pump displacement is the main factor affecting the success or failure of the sand control technology.Through computer simulation of pore throat structure in the gravel layer,the distribution curve of pore throat structure and the distribution curve of formation sand grain size are used to optimize the gravel size.A well in Bohai oilfield is designed with high-pressure gravel packing,and the sand control effect is good.
