目前国内外划分油田开发阶段的方法,只采用影响和反映油田开发效果的某个单一因素,不易全面反映一个油田(藏)的开发效果和特点。建议以采油速度为基础,结合油田(藏)含水率(水驱油田)或油层压力(非水驱油田)变化来划分开发阶段。这种划分方法的指标和标准,基本适用于各种不同类型的油田(藏)。 At present, the method of dividing oilfields at home and abroad only uses a single factor that affects and reflects the effect of oilfield development. It is not easy to fully reflect the development effects and characteristics of an oilfield. It is suggested that the development stage be divided on the basis of the oil recovery rate, in combination with the changes in the (reservoir) moisture content (water-driven oil fields) or reservoir pressure (non-water-flooded fields). The criteria and criteria for this classification are basically applicable to various types of oil fields.
