柴达木盆地涩北气田出水井产气剖面曲线特征

Gas Production Profile Curve Characteristics of Wet Wells in Sebei Gas Field in Caidamu Basin

柴达木盆地涩北一号、二号气田具有天然气甲烷含量高、纯度高、地层水矿化度高的特点。利用持水率、流体密度、流量、压力等资料可以定性分析整个井的出水状况,进一步综合流温、自然伽玛曲线的信息,可以定性识别具体的出水层位。在分析涩北气田出水井产气剖面曲线特征的基础上,总结出利用产气剖面资料在涩北气田找水的方法。

Natural gas from No. 1 and No. 2 gas fields in Caidamu basin is characterized by high content methane, high purity and high formation water salinity. Qualitative analysis on water production status of the whole well can be done by use of water holdup, fluid density, flow rate and pressure etc. Qualitative identification on specific water producing zone can be done by further combining flow temperature and natural gamma curve. Based on the analysis of gas production profile curve characteristics of wet well in Sebei gas field, searching water methods by use of gas production profile is summarized.
