There are downhole safety valves and permanent packers in the completion string of the three high deep wells. Conventional pump processes such as rod pumps and electric pumps cannot meet the requirements of drainage depth, and pump processes are not suitable for acidic corrosion environments, gas lift and bubble drainage are not mature in well depths, and are limited by acidic environments. However, it is necessary to establish channels that can circulate. This article focuses on permanent packer wells, and conducts research on gas lift parameters, gas lift tools, and how to establish drainage and gas production channels in the oil casing space. It points out the corresponding displacement of different gas lift parameters, and proposes different methods and supporting processes and tools for establishing gas lift circulation channels, providing a solution for the safe and efficient development of three high deep wells.
