| 摘 要： | 注聚区油井砾石分级充填防砂工艺技术是针对胜利油田注聚区见聚油井产出液黏度增大、携砂能力增强，提液引效措施加剧油井出砂使油井防砂有效期变短等问题进行研究的。该技术是在注聚区油井充填防砂时改变过去采用单一粒径砾石进行充填防砂的做法，将不同粒径砾石按不同比例分级充填到近井、炮眼附近和筛套环空，同时在中粒度粒径的砾石中加入经过表面处理的短切纤维，提高了砾石充填挡砂屏障的挡砂强度，实现了挡砂屏障的“挡砂、稳砂、排砂”的功能。截止到2010年4月底，该技术现场累计推广应用32井次，分级充填后注聚区油井液量由27．2m3提高到40．43m3，油量由1．01m3提高到3．89m3，增幅分别达40％和80％，最长防砂有效期已达到400d。该技术的研发和应用，较好地解决了注聚区油井提液引效使防砂有效果变短和油井近井堵塞的问题，具有良好的应用前景。

| Abstract: | Gravel classified pack sand control technique is developed in view of liquid viscosity increase aggravating sand production and shortening ,sand control validity term and high viscosity production fluid intensifying proppant carrying capacity in polymer walerflc~ting wells in Shengli Oilfield. The technique is that varigrained gravel is packed to near wellbore area, perforation cylinder, and screen jacket annulus, and chopped fibre is added to middle grained gravel to increase sand retention ability. The technique have revised the method of work that identical size gravel are packed to formation, and sand retention, sand consolidation, sand dump are achieved. The technology is applied to 32 wells in site. The liquid lifts from 27.2 m3/d to 40.43 m3/d, and oil production increases from 1.01 m3/d to 3.89 m3/d. The validity term of sand control has exceeded 400 days. The technology prolongs the sand control expiration date of oil well and has acquired good dfect in polymer waterflooding wells. |
