Study on water producing characteristics and development adjustment of Xu'er gas reservoir in Pingluoba gas field

This paper investigates water producing characteristics in Xu'er gas reservoir of Pingluoba gas field,discriminates the stages and ways of water producing,defines water sources of gas wells including interstitial water,edge water,interbedded water and so on,and analyzes gas well production characteristics when water is produced from different sources.This research provides in-depth understanding of the reasons of water invasion in gas reservoirs and is of practical significance to future production and development.
