套管贴堵和侧钻井技术在井网调整、盘活报废井等方面具有明显技术优势,是采油厂措施挖潜的重要手段,但贴堵和侧钻后,套管的尺寸小、类型多,制约了常规机械防砂工艺的应用。本文研发小直径防砂工具,对防砂工艺及充填砾石进行优化筛选,通过对化学防砂配方的优化,提高其胶结强度,达到小井眼防砂的目的。
Casing plugging and side drilling technology have obvious technical advantages in well pattern adjustment and rejuvenation well etc. It is an important measure for tapping the potential of oil recovery measures. However, the size and type of casing after the sticking and lateral drilling are small The conventional mechanical sand control technology applications. In this paper, a small diameter sand control tool is developed to optimize the sand control technology and filling gravel. Through the optimization of the chemical sand control formula, the cementing strength is improved and the purpose of sand control of the slim hole is achieved.
