摘　　要：目前涪陵页岩气田P区块气井生产已进入产量递减阶段。针对P区气井低压影响因素多,复产困难的情况,从气藏地质特征分析及单井开采指标评价的基础上,将复产困难的异常井分为地层能量差、携液能力不足、产水量大三类,使用不同类型的复产方式解决复产问题,为气田稳产提供有力的支持。根据这种分类方法进行气井针对性复产的体系,对涪陵页岩气田主区块有着较大的参考价值。At present, the gas well production in Block P of Fuling shale gas field has stepped into the production decline. In view of the multiple factors affecting the low pressure of gas wells in Block P and difficult reproduction, and based on the analysis of the geological characteristics of gas reservoirs and the evaluation of single-well production metrics, the abnormal wells with difficulty to resume production are divided into three categories: poor formation energy, insufficient fluid-carrying capacity and large water production. Different reproduction methods are used to address the issue of production resumption and provide strong support for the stable production of gas fields. The reproduction system for the gas well based on this classification is of great reference for the main block of Fuling shale gas field.
