摘要
针对胜利油田桩西滩海地区高泥质疏松砂岩实施常规防砂产生的堵塞问题,提出并实施了酸化防砂技术,重点讨论了堵塞原理及该项工艺的室内模拟解堵试验结果。生产实践及室内研究表明,在桩106块采用常规的方法难以取得较好的效果,必须把防砂工艺与解堵工艺结合起来,才能达到比较理想的效果。
According to the plugging problems caused by conventional sand control technology in loose argillaceous sandstone in Zhuangxi area of Shengli Oilfield, the paper put forward acidizing sand control technology, analyzed the plugging principle and the test result of simulation broken down. Production practice and lab research result proved that using conventional sand control method couldn't obtain good result, sand control technology and broken down technology must combine to achieve the ideal effect.
