针对青海油田中浅层细粉砂岩油藏开采过程中严重出砂的问题 ,提出了应用新型改性呋喃树脂固砂剂的 3种配套防砂工艺 :直接固砂工艺、压裂固砂工艺和多级闭合酸酸化固砂工艺。固砂效果表明 ,该固砂剂及配套防砂工艺非常适合青海油田中浅层细粉砂岩气井防砂 ,解决了该油田长期以来未攻克的气井防砂难题 ,取得了较大的经济效益
Aiming at the serious sand production during the process of middle and fine siltstone reservoir exploitation in Qinghai Oilfield, three kinds of sand control technologies applying the new modified furan resin sand fixing agent are put forward: direct sand consolidation, fracturing and sand consolidation, and more Level closed acidification sand process. The solid sand effect shows that the sand-fixing agent and the sand control technology are very suitable for the sand control of medium and fine siltstone gas wells in Qinghai Oilfield and solved the problem of sand control of the gas wells that have not been overcome for a long time, and achieved great economic benefits
