高压充填一次管柱防砂工艺技术的讨论高压充填一次管柱防砂工艺技术的讨论 摘要：该技术是在总结压裂防砂、常规机械防砂优缺点基础上,针对疏松砂岩油层防砂需要而开发的新技术，是在地层压裂充填石英砂的基础上, 利用绕丝管阻挡石英砂,再利用石英砂阻挡地层砂，屏障范围大,对粉砂、粉细砂而言效果好于其它防砂措施
高压充填一次挤压防砂工艺对管柱结构、工具进行改进,调整优化了施工参数, 具有施工周期短、成本低等优点
关键词：防砂; 高压充填; 砾石 Abstract: The technology is based on summed up in the fracturing sand, conventional mechanical sand control the merits, the development of new technology for unconsolidated sandstone reservoir sand needs and, it is in the formation fracture filling quartz sand foundation, using the wire around the tube stop quartz sand, quartz sand blocked by sand barrier layer, large range silt, silty sand, on terms effect than other sand prevention measures
High pressure filling an extruded sand control technology on pipe string structure, tools are improved, the adjustment and optimizatio
