摘　　要：高压充填防砂是以砂防砂的油水井防砂工艺技术。携砂液在高压作用下进入地层,在油层形成稳定的砂桥,阻挡低渗透储层疏松砂岩随油水进入井筒,形成砂埋或者砂卡,从而提高防砂效果,延长油水井作业周期。该项技术在孤岛油田现场实施,见到了良好的效果。High pressure packing sand control is to control sand with sand. The carrying fluid enters formation at high pressure and forms stable sand bridge to prevent the loose sand in low permeability reservoir from entering wellbore along with oil and water and forming sanding-in, thus to improve sand control effect and extend the operation period of wells. This technology has been used in Gudao Oilfield and achieved good result.
