摘　　要：四川盆地岩盐矿床成矿时代早,埋深较深,盐层厚度不大而变化较大,矿层围岩力学性质较好,但节理裂隙以及盐构造非常发育。在一些矿山,因地质情况复杂多变和老卤井长期采卤对采区的影响,使得建设高质量新井组变得困难。只有充分研究地质、构造、资源和卤井溶腔等各方面存在的问题,优化钻井设计方案,才能确保新井组顺利投产和长期稳定生产。The rock salt deposits in Sichuan Basin have an early metallogenic generation,a deep burial depth,a small salt layer thickness and a great change,and good mechanical properties of the surrounding rock,but joints,cracks and salt structures are well developed.In some mines,it is difficult to build high-quality new well groups because of the complex and changeable geological conditions and the influence of long-term brine extraction from old brine wells on the mining area.Only by fully studying the problems existing in geology,structure,resources and brine well cavity and optimizing the drilling design scheme can we ensure the smooth production and long-term stable production of the new well group.
