提出了一种用注水速率的细微变化来描述注水井和生产井之间流动单元的新方法。该方法可以计算注水井对周围生产井重力因素的影响。重力因素用来描述在生产井周围对生产总值有有效贡献的注水井的影响。小波理论在注水速率方面设计微扰,以便分析生产总值的变化。在注水优化系统中,跟踪注水井对各种生产井的贡献对平衡充填亏空有帮助。另一个是在油藏描述方面的应用,过程所提供的资料可以帮助绘制高渗透流动单元,如孔道和裂缝以及井间流动障碍。该方法已成功地针对模拟线性驱动和拥有各种假设的流动单元及流动非均质性的五点井网条件进行了校准和测试。在一个致密油层水驱实例中,重力因素用来划定引起优先流动的自然裂缝结构。
A new method of describing the flow cell between a water injection well and a production well using subtle changes in water injection rate is proposed. This method can calculate the effect of injection wells on the gravity factors of the surrounding production wells. The gravity factor is used to describe the effect of a well that contributes effectively to the total product value around the production well. Wavelet theory is designed to perturb the water injection rate in order to analyze changes in the gross product. In a water injection optimization system, tracking the contribution of a water injection well to various production wells is helpful in balancing the filling deficit. The other is the application of reservoir description. The process provides information that can help to map high-permeability flow cells, such as channels and cracks, and cross-flow barriers. The method has been successfully calibrated and tested for five-point well conditions that simulate linear drives and flow cells with various assumptions and flow heterogeneities. In the case of a tight reservoir waterflood, the gravity factor is used to delineate the natural fracture structure that gives rise to preferential flow.
