生产水气比对气井产能影响规律研究
摘要
Abstract
In the process of gas reservoir exploitation, formation water encroachment and condensate water congregation at bottom hole will lead to increasing of water cut and decreasing of gas permeability near well bore, thus adversely affecting gas well productivity. From the perspective of changing WGR in gas well, pseudo steady - state flow deliverability equation is combined with gas -water relative permeability curve, and the deliverability equation under different producing WGR is amended using equivalent skin factor, thereby derived the impact of producing WGR on gas well productivity, which has been verified to be accurate and reliable through example calculation.关键词
