摘　　要：普光气田大湾-毛坝区块地层构造相对复杂,钻遇多个层段且层间差异大,完井方式多样。目前高含硫气井均采用永久式完井管柱一次性投产,无法满足逐层上返开采的地质要求,因此亟需研究针对不同井况的上返投产工艺。The Dawan-Maoba block of the Puguang Gas Field has relatively complex stratigraphic structure,encountering multiple layers with large interlayer differences,and various well completion methods.High-sulfur gas wells all use permanent completion strings to be put into production at one time,which cannot meet the geological requirements of layer-by-layer upback mining.Therefore,it is urgent to study up-and-back production processes for different well conditions.

关 键 词：大湾-毛坝区块 永久式完井管柱 上返投产
