摘　　要：高速水砾石充填防砂施工过程中砾石尺寸、携砂比、充填排量、充填压力、环空压力等是影响施工成败和防砂效果的主要因素。根据地层的破裂压力与地层渗透率数据,建立了携砂比、充填压力、环空压力、充填排量以及返出排量控制的方法,用以对施工参数进行组合优化设计;给出了一套高速水砾石充填施工参数优化设计方法,用该方法对渤海某平台9口井进行了高速水砾石充填设计,施工后防砂效果较好。During HRWP(High Rate Water Pack)operations,the gravel size,sand concentration,pump rate,wellhead treating pressure,annulus pressure etc are the main factors to affect the operation success and sand control effectives.According to the formation fracturing pressure and permeability data,setting the sand concentration,gravel pack pressure,annulus pressure,pumping rate and the return rate control method,to optimize the operation parameters.A set of HRWP operation parameters optimizing method is setup in this article.9 wells HRWP operations are designed by using this method,and good results are achieved.
