吐哈油田伴生气产量变化规律

The Variation of Associated Gas Production in Tuha Oilfield

对吐哈油区主要油田伴生气的生产现状、能力及生产水平进行了全面调查分析,用多种方法研究了伴生气的变化规律,探讨了生产气油比随压力与含水等因素的变化关系,为油区天然气开发规划的编制提供了可靠的参数依据。指出,地层压力、含水率及开采方式的改变均会影响油气比的变化,它们对气油比影响程度的变化是地层压力,次为采油方式,最后为含水率。因此,应坚持保压开采的技术路线。

This paper presents the all-around investigation and analysis of production status, production capability and production level of associated gas in major fields of Tuha region, of which many methods are used to study the variation of associated gas and relations of production GOR to pressure and water cut, etc. These reliable parameters can be helpful to preparing the natural gas development plan of this region. Study shows that the GOR changes could be affected by the changes of formation pressure, recovery process and water cut in turn. Therefore, the scheme of production with keeping formation pressure should be unalterable.
