本文介绍了锦州油田某井作业中一种新的裸眼防砂管柱组合形式,采用尾管挂代替顶部封隔器携带筛盲管进行防砂作业,突破了常规防砂管柱中顶部封隔器及其坐封工具在抗拉、抗压等方面的限制,保证了复杂情况下的有效处理手段。此项技术通过增强防砂管柱遇阻、遇卡后的处理能力,提高了管柱顺利到位的成功率,避免了管柱打捞、井眼侧钻等复杂情况发生,对于复杂裸眼井防砂管柱组合有一定指导意义。
In this paper, a new combination of naked eye and sand control column in a well operation in Jinzhou Oilfield is introduced. The tail pipe is used instead of the top packer to carry the sand control operation, which breaks through the top packer in the conventional sand control column and its Setting tools in the tensile, compression and other restrictions, to ensure the effective handling of complex situations. This technology improves the successful success rate of the pipe string by enhancing the handling resistance of the sand control string and the handling capacity after the card encounter, avoiding complicated situations such as string fishing and side hole drilling. For the complicated open-hole sand control string Combination has some guiding significance.
