随着油田开采,丢手封隔器在油水井的生产中普遍使用,使用技术也在不断地慢慢成熟和完善。但对于丢手封隔器失效,且上部被沉砂所埋或腐蚀损坏内腔有落物,造成打捞难度加大,我们通过多次试验,总结出了经验。值得在今后的工作中推广。 With the exploitation of oilfields, throw-away packers are commonly used in the production of oil and water wells, and the technologies used are gradually maturing and perfecting. However, for the failure of the lost packer, and the upper part is buried by sand grit or corroded and damaged lumen has fallen into pieces, which makes it more difficult to salvage. Through many experiments, we summed up the experience. It is worth promoting in future work.
