补充资料: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。
