摘要
随着大牛地气田开发的深入,地层能量衰减,携液能力下降,积液、水淹现象频繁出现,泡排、气举、速度管等工艺在应用效果及经济效益上不能满足气田开发需求。智能柱塞气举工艺技术将柱塞排水采气工艺与智能控制系统结合,根据气井运行数据,通过远程控制软件对工作制度进行优化分析、更新设置,实现气井远程控制、精细化管理。通过D66-A井的现场实践,平均日产气由1083 m^3提高到1335 m^3;平均日排水由0.15 m^3提高到0.49 m^3,降压带液次数由3-4次下降为0次,提高了排水采气效果。该技术可实现低产、低效气井产量与排液效果的双提升,为实现油气田精细化管理提供技术支持。
With the development of the Daniudi gas field,the formation energy decreases and the carrying capacity drops,which frequently causes liquid accumulation and water out.The technologies such as foam flooding,gas lift and velocity string cannot meet the development demand of the gas field in terms of application effect and economic benefits.The intelligent plunger gas lift technology combines the plunger drainage gas production process with the intelligent control system.According to the operating data of gas wells,the remote control software is used to optimize and analyze the working system and update the settings,so as to realize the remote control and fine management of the gas wells.Through the field application of Well D66-A,the average daily gas production increased from 1083 m^3 to 1335 m^3,the average daily drainage increased from 0.15 m^3 to 0.49 m^3,and the number of depressure and fluid carrying decreased from 3-4 times to 0,which improved the effect of drainage and gas production.This technology can improve the production and drainage efficiency for low-production and low-efficiency gas wells,providing technical support for the fine management of oil and gas fields.
