| Abstract: | To the feature of injection/down pressure testing and fracturing for separated layers in coal methane bed well,a new type combing pipe string of ZY plug ZY221 packer has been developed and applied which successfully replaced the operation stem of using double packers to separate layers. It is realized that injection/down pressure testing and fracturing to separated layers with many layers in one well by once testing stem which increases operation successful ratio,shortens testing period and has an obvious economical benefit. |
