Coalbed-methane horizontal-well PE (poly ethylene) screen pipe well completion application process method

The invention discloses a coalbed-methane horizontal-well PE (poly ethylene) screen pipe well completion application process method and belongs to the technical field of coalbed-methane drilling well completion engineering. The method includes the steps of manufacturing of PE screen pipes, well completion of the PE screen pipes, pumping of the PE screen pipes and anchoring of the PE screen pipes. The coalbed-methane horizontal-well PE screen pipe well completion application process method has the advantages that the coalbed-methane horizontal-well completion PE screen pipes different in size and capable of meeting intensity and liquidity requirements are rapidly and conveniently designed for field application, PE screen pipe well completion of coalbed-methane horizontal well sections can be achieved, and great importance is achieved for solution about bottleneck technical problems restricting coalbed methane development due to coalbed collapse and plugging of boreholes by deposition of pulverized coal and ensuring of efficient and safe production of coalbed-methane horizontal wells.
