针对现有联作工艺对老井复查、备层开发不适用 ,常出现环空打压污染已射层、环空憋压达不到点火头设计压力而造成射孔失败的情况 ,经过研究提出了跨隔旁通管联作工艺方案 ,用双封隔器隔开已射层 ,中间通过柔性旁通钢管传压 ,使压力传递在密闭环境中进行 ,可解决环空打压会污染测试层以上的已射层的问题。分析认为 ,该工艺方案具有可行性、实用性 ,已具备开发、推广的条件。 In view of the existing co-production process for the review of the old well, spare layer development does not apply, often appear annular pressure pollution has been shot, annular pressure holding pressure less than the design pressure of the ignition head caused by the failure of perforation, after research proposed Cross-separated by bypass pipe cross-process scheme, with dual packer separated layer has been shot through the middle by flexible bypass pipe pressure transmission, the pressure transmission in a closed environment, to solve the ring pressure will pollute the test layer above The problem has been shot layer. Analysis, the process is feasible, practical, has been developed, the promotion of the conditions.
