摘　　要：经过持续努力和攻关,海上某气田在低渗储层应用取得良好效果。但是,也有部分井压后效果没有达到预期要求,这样造成主要靠低渗储层贡献产能的采油平台生产能力低,油田开发效益较差。为了进一步挖潜储层潜能,提高单井产能,本文通过选井选层研究,形成海上气田重复压裂选井选层方法,完成候选井层优选。同时进行重复压裂工艺优选及工艺参数优化,并在A4井进行现场试验,取得良好增产效果。After continuous efforts and research,offshore gas field made a good effect in low permeability reservoir applications.However,there are some wells did not meet expected requirements after fracturing.This caused mainly by the contribution of low permeability reservoir oil platform production capacity is low,poor oil field development benefit.To further tap the potential reservoir potential to improve well productivity.Through well and layer selection,forming offshore gas field refracturing well and layer selection method, complete candidate well layer preferably.At the same time,preferably refracturing and optimization of process parameters and field trials A4 well,get good yield.
