油井防砂和清砂 对疏松油层进行层内胶固，在井筒内下筛管防止油层砂进入井内，以保证油井、注水井的正常生产，称防砂。 防砂 胶结疏松的砂岩颗粒随油、水进入井筒或携带至地面，会冲蚀、磨损、堵塞深井泵和管线以及地面设备,或沉积于井底,堵塞油层，使油井减产或停产；甚至油层坍塌，挤毁套管，导致油井大修或报废。采油时应根据生产动态、砂样分析及声波测井等资料，及时了解出砂原因、层位及性质，采取有效的防砂措施。防砂措施有筛管滤网和化学胶固两类，前者适用于各种完井方式，应用较广，后者主要用在套管射孔完成的井。通过试油、试采已证实出砂的油层，应考虑防砂完井。 筛管滤网防砂 也称机械防砂，将多缝筛管固定在带孔的钢管上，下至出砂层段并用携砂液将一定粒径的砂粒循环填充于筛管外，靠管外砂粒所形成的桥拱，滤阻油层出砂。对油层单一、无水、气夹层的井，可采用先期防砂。即油层部分用扩眼钻头扩眼后，再下入筛管填砂（见图）。对多层合采或有水、气夹层的井，用射孔完井。清洗套管和炮眼后，再在套管内下筛管填砂。筛管的结构，从割缝到外包金属网或预填砾石，发展到用有机或无机材料预制滤管。目前多用梯形截面的不锈钢丝点焊成强度高、渗滤面大、耐腐蚀的金属绕丝滤管。此法要求根据砂样粒度分析资料，选定筛管缝宽及填入砂粒的直径。 化学防砂 向出砂油层注入一定量的化学胶结剂，将油层砂子胶固在一起。常用的胶结剂有树脂类（如酚醛树脂、环氧树脂等），有时也用水泥类材料。要求胶结剂在固结时体积收缩，或加入增孔剂，造成一定的渗透性，以尽量减少对产量的影响。对已经大量出砂的油层，用下列方法形成有渗透性的人工井壁：①将砂与胶结剂按比例混合后,挤入地层；②预先向出砂层填砂,再将原料如甲醛和苯酚以及固化剂按序挤入地层，在地层条件下合成树脂；③石英砂外包一层树脂，在未完全固化前挤入地层，在油层温度条件下固化；④用N2作载体把SiCl4蒸气引入油层，使之分解,析出的Si对疏松砂子起胶结作用。化学防砂的优点是可用于同井多油层防砂，不缩小井眼；缺点是成本较高，易降低出砂层的生产能力，对于油井先期防砂或注水井防砂，效果较好。 清砂 清除井底沉砂，一般下入油管，用洗井液循环冲洗，带出地面。炮眼内积砂，用专门的洗井封隔器分段冲洗。井下深井泵等设备内的积砂，须将设备起出地面，检查清理。 参考书目 T.
