摘要
渠盐2井为一口老卤井,地下有多个因侧钻而形成的老溶腔,最近因出卤浓度降为零而被迫停产。要恢复渠盐2井正常采卤生产,并实现充分开采岩盐矿,为下一步渠盐1井侧钻水平井奠定基础,就必须采用定向侧钻采卤技术,优化设计侧钻井眼轨迹,避开原老溶腔,合理选择新靶区。
Quxian Salt Well No.2 is an old brine well,in which there exist several old underground cavities formed by lateral drilling.h has been shut down recently because of zero salinity of brine produced. In order to restore the normal brine extraction,realize adequate rock salt mining and lay a foundation for the lateral drilling for horizontal well in Quxian Salt Well No.l,directional lateraly drilling technonology for brine extrac- tion has to be used, optimize the design for the track of lateral drilling in well bore, avoid original old cavities and reasonably select a new drilling target.
