摘要
制定煤系气合采井排采全生命周期的合理排采工作制度能为气井高产提供重要保障。以五里堠井田3#+4#煤层、夹层砂泥岩、15#煤层为产气层,基于生产特征划分了排采阶段,制定了不同排采阶段的排采工作制度和核心目标,现场排采产气效果良好。该研究成果为煤系气合采井全生命周期排采工作提供了借鉴。
The development of a reasonable drainage working system for the whole life cycle of coal-measure gas wells can provide an important guarantee for high production of gas wells.Taking 3#+4#coal seam,interlayer sand mudstone and 15#coal seam in Wulihou Mine Field as gas producing layers,the drainage stages were divided based on production characteristics,and the drainage and mining working system and core objectives of different drainage and mining stages were formulated.The gas production effect of the field drainage and mining was good.The research results provide a reference for the whole life cycle drainage of coal-measure gas wells.
