摘　　要：高压充填工艺技术以PFS高压封隔充填工具密封筛套环形空间 ,采用压裂车组和合适携砂比实现地层填砂及绕丝管外充填一体化 ,在高压下形成了连续性好、高渗透、大半径的防砂体系。经孤东油田应用证明 ,该技术较好的解决了防砂与防堵塞的问题 ,防砂一次成功率高、有效期长 ,具有适合油井各个阶段防砂的特点。Highpressure packing is a technique in which screen casing annulus is sealed by highpressure packing tool of PFS, and sand control system with good continuity, high permeability and big radius will be formed at high pressure using fracturing truck group and right sandtransport ratio in integrated formation gravel input and wire wrapped liner outside packing. The application in Gudong oilfield proves that the technique can solve the problem of sand control and anticlogging with high success ratio at first time and long validity in sand control, which is suitable for the features of sand control at each stage in oil wells.
