摘　　要：南海西部涠洲某油田待开发油组存在出砂风险。根据Saucier提出的最优砾石尺寸设计方法,进行防砂精度初步设计。使用地层岩心砂,进行筛管挡砂介质和砾石层进行挡砂驱替实验,评价及论证筛网与砾石挡砂效果,进一步论证设计挡砂精度的合理性,并验证放大筛管挡砂精度的可行性,为防砂方案提供参考。本评价方法可为海上油田防砂效果评价提供参考。There is sand production risk in the oil formation to be developed in Weizhou oilfield in the west of South China Sea.According to the optimal gravel size design method proposed by Saucier,the preliminary design of sand control accuracy is carried out.The core sand of the formation is used to conduct sand retaining and dis⁃placement experiments on screen tube sand retaining medium and gravel layer,evaluate and demonstrate the sand retaining effect of screen and gravel,further demonstrate the rationality of the designed sand retaining preci⁃sion,and verify the feasibility of enlarging the sand retaining precision of screen tube,so as to provide reference for the sand control scheme.This evaluation method can provide reference for sand control effect evaluation of off⁃shore oil field.
