水驱开发是一种已得到广泛应用的提高原油采收率技术 ,但在实际的开采动态中如何监测到水流方向仍是困扰油藏工程师的主要问题之一。即使在十分均质的油藏 ,也存在同样问题 ,这种水驱动态主要受注采井网、流体性质和油藏非均质等的影响。因此 ,为实现优化水驱 ,必须对实际的水驱动态进行实时监测。最好最有效的方式就是联合应用储层饱和度和生产测井工具来实现。储层饱和度测井仪 (RST)可以为套管井提供测试含油饱和度的方法 ,一种是中子俘获截面测井 ,另一种是碳氧比测井 ,后者尤其适用于淡水环境和未知矿化度的环境。而另一方面 ,生产测井可以提供流体地下分布和流体类型以及井筒内外流体的流动原因。在关井周期和排液周期进行测量还可得出随时间变化的流动动态。本文以埃及的苏伊士海湾石油公司的Younis油田为例来阐述水驱动态监测的应用 ,并且对数据进行分析 ,通过分析 ,综合各种测试信息 ,提出一种预测结果或者说是假设 ,对这种预测结果再用生产数据、注水数据和其他数据进行检验。不断重复计算 ,直到得到一个令人满意的结果。该方法在水驱开发评价以及注采井网优化组合调整中具有很高的应用价值 Water flooding development is a widely used technique to enhance oil recovery. However, how to monitor the water flow in the actual exploitation is still one of the main problems that plague reservoir engineers. The same problem exists even in very homogeneous reservoirs, which are mainly driven by wellbore and fluid properties and reservoir heterogeneities. Therefore, in order to achieve optimal waterflooding, it is necessary to monitor the actual waterflooding status in real time. The best and most effective way is to combine reservoir saturation and production logging tools. The Reservoir Saturation Tool (RST) provides a method for testing oil saturation for cased wells, one for neutron capture cross-section logging and the other for C / O logging, which is especially suitable for freshwater environments and Unknown salinity of the environment. On the other hand, production logs can provide a proxy for the fluid distribution and fluid type and fluid flow inside and outside the wellbore. Measurements during the shut-in and drain cycles also give flow dynamics over time. This paper takes the Younis oilfield of Egypt’s Sue Gulf oil company as an example to illustrate the application of water-driven dynamic monitoring and data analysis, through analysis, a variety of test information, put forward a prediction or hypothesis, this The forecast results are then tested with production data, water injection data and other data. Repeat the calculation until you get a satisfactory result. The method has high application value in the evaluation of water flooding development and adjustment of optimal combination of injection and production well pattern
