摘要
分析了中国石化金坛储气库4口先导造腔井在造腔期间影响作业时效的井下复杂情况和设备不配套等主要原因。通过对这些原因的分析和总结,进行优化作业工序、完善技术规范和设备配套,并建立作业示范队伍,提高了作业时效,节省了作业费用。
The factors of influencing the downhole operation efficiency in the construction of four cavity-made wells of Jintan gas storage are analyzed, and it is held that downhole complex situation and inappropriate equipment are main influencing factors. Finally the downhole operation efficiency is improved and operation cost is reduced by analyzing causes, optimizing operation processes and perfecting technical specifications and equipment.
