摘　　要：涩北气田具有气藏埋藏浅,储层岩性疏松,易出砂,含气井段长,气层层数多且薄,弱边水弹性气驱,气水分布复杂的特点。随着气田不断开发,气井出水情况日益复杂化,气田找水面临的困难和挑战越来越大,如何找准出水位置、准确计算产水量,为气田"降水防砂采气"提供可靠依据变得尤为重要。文章通过对该气田应用的多种测井技术进行研究,分析各技术特点,对涩北气田找水提出了以主体技术+辅助技术的测井工艺,定性识别+定量计算的解释技术。实践应用表明,解释结论与实际生产有较高的一致性。Sebei gasfield has the following complex features of shallow gas reservoirs,unconsolidated reservoir rock,long gas-contained well section,multiple and thin gas-bearing bed,thin edge-water-elastic-drive and complicated distribution of gas and water.With the continuous development of gasfields,the situation of water production becomes more and more complex. The difficulties and challenges of finding water in gasfield is growing as well. Therefore it becomes very important to provide solid method to achieve the goal of ' dewatering sand control and gas production' by finding how to identify water location and accurately calculate water production for the gasfield. By studying the application of a variety of well logging technologies and analyzing the corresponding technical characteristics,this paper proposes the following logging technology in order to find water in sebei gasfield:main technology together with assistive technology,qualitative identification together with quantitative calculation of logging process. Practice has proved a high consistency between the data interpretation conclusion and gas production.
