    摘要:

    为了解决深水挥发性油田中高含水阶段生产井停喷风险日增的问题,以西非尼日尔盆地Akpo油田为例,以储层构型分类研究为基础,利用Akpo油田典型井实际生产资料,通过动态相渗规律性研究预测不同储层条件下生产井含水及液量等生产动态指标的变化规律,最终建立一套适用于深水挥发性油田生产井井口压力变化规律及停喷时机预测方法。结果表明:①深水挥发性油田自喷井井口压力变化规律主要受到含水及液量的影响,不同储层条件下生产井动态变化规律不同;②自喷井生产后期停喷风险日益增大,通过改造一级分离器压力模式可有效延长生产井自喷寿命,经济效益显著;③研究方法预测精度较高,可直接用于指导现场生产,研究思路及流程为深水油田开发后期调整提供理论基础和技术支持。

    Abstract:

    In order to research the problem of rapid increase in risk that production wells stop flowing during the middle and high water cut stage of deep-water volatile oilfields, this paper, taking Akpo oilfield in Niger Basin of West Africa as an example, relying in the research of reservoir configuration classification, using the actual production data of typical wells in Akpo oilfield, and through the study of dynamic phase permeability regularity, predicted the change law of production dynamic indexes such as water cut and liquid flow in production wells under different reservoir conditions, and then established a set of prediction methods for the change law of production’s wellhead pressure and the stop flowing timing in deep-water volatile oilfields. The results indicated that: firstly, the change law of wellhead pressure in deep-water volatile oilfields is mainly affected by water cut and liquid flow, and the dynamic change law of production wells is different under different reservoir conditions; the risk of quitting flow is raising in the later stage of development, but the flowing phase of production wells can be prolonged effectively by reforming the pressure mode of the first separator, and the economic benefit is remarkable; the research method has high prediction accuracy and can be directly used to guide field production, and the research ideas and processes provide theoretical basis and technical support for the later adjustment of development in deep-water oilfields.
