增压气举排液采气技术在文23气田的应用

Application of Gas Recovery by Liquid Drainage in Wen 23 Gas Field

文23气田经过近三十年的开发,地层压力逐年下降,积液井日益增多,严重地影响着气田的稳产。排液采气工艺在提高气田采收率、提高气井开井率方面显得尤为重要。本文结合文23气田的开发实际,从增压气举参数的优化,地面管网流程、集气站内流程、计量配套流程的完善以及文丘里气咀的应用等方面全方位地介绍了增压气举排液采气技术,该项技术通过推广应用,取得了良好的排液增产稳产效果。

Wen 23 gas field passed near 30 years exploitation. Declining ot formation pressure ana increasing the number of liquid loading wells, which serious influenced development of gas field. Gas lift flowing back is important for enhancing recovery and times of gas production. This paper introduced technologies of gas recovery by liquid drainage according to the realities of gas field exploitation. The technologies include optimization of gas lift parameters and flow net of pipelines and measuring flow perfecting. The technologies have achieved success in field application in Wen 23 gas field.
