摘　　要：基于涪陵页岩气田页岩气井生产动态资料和气井废弃条件,应用不稳定产量分析方法分析气田增压开采潜力;比选多种增压方式,结合气量预测进行压缩机进出口压力选型。结果表明:增压开采潜力大小与增压前技术可采储量具有明显相关性,通过增压开采可提高技术可采储量0.18亿方左右;集气站增压方式与气田山地中压集输管网和气田滚动开发模式匹配性最好;增压开采是改善页岩气井低压低产阶段生产效果的有效措施。Based on the production performance data of a shale gas well and the abandonment conditions of a gas well in Fuling shale gas field,the pressurized production potential of the gas field was analyzed by using the unstable production analysis method.The advantages and disadvantages of various pressurization methods are compared,and the inlet and outlet pressure of the compressor is selected according to the forecast of gas volume.The results show that there is a significant correlation between the potential of pressurized production and the technically recoverable reserves before the pressurized production ,and the technically recoverable reserves can be increased by about 18 million m^(3) through the pressurized production.The pressurization pattern of a gas gathering station has the optimal matching with the medium-pressure gathering and transmission pipeline network in the mountainous area and the progressive development of the gas field.Pressurized production is an effective measure to improve the production effect of shale gas wells in the phase of low pressure and low production.
