摘要
气井出水导致气井产能明显下降,同时出水也增加了流体在管柱中的流动阻力,加剧了井筒内的举升矛盾,导致气井生产困难。本文引入变工作制度测井,通过分析PLT测井曲线在目的层段的响应特征,准确的找出低出水井地层出水的位置,为堵水上产措施提供可信的参考依据。实际应用表明,变工作制度测井在确定气井出水点位置中有较好效果。
Water producing leads to obvious decline of gas well deliverability and it also increases fluid flow resistance in the pipe string and intensifies the lift contradiction in the wellbore,resulting in gas well production difficulty.This paper introduces the variable work system logging.Through analyzing the response characteristics of objective interval on PLT logs,accurate identification of the position of low water production provides a credible reference for water shutoff.Practical application shows that variable working system logging is effective in determining the location of water producing in a gas well.
