一种动态储量计算新方法在渤海油田的应用
|
摘要
针对海上油田开发的特殊性,应用常规方法准确求取动态储量存在诸多难题。为了克服现有方法的局限性,基于Leverett函数式及前缘推进方程,创新引入相对渗透率的比值与含水饱和度的多项式函数,通过理论推导,建立了计算动态储量的新模型。研究表明,该方法使用简单,仅需油田相对渗透率资料及动态数据,实用性强。研究结果可有效指导油田储量规模再认识,指导油田调整井实施,为渤海油田增储上产、后续油田高效开发提供理论基础。
In view of the particularity of offshore oilfield development, there are many difficulties in obtaining dynamic reserves accurately by using conventional methods. In order to overcome the limitations of the existing methods, based on the Leverett function and the leading edge equation, the polynomial function of relative permeability ratio and water saturation was introduced innovatively.Through the theoretical derivation, a new model for calculating dynamic reserves was established. The research shows that this method is simple, requires only oil field infiltration data and dynamic data, and has strong practicality. The research results can effectively guide the understanding of the scale of oilfield reserves and the implementation of oilfield adjustment wells, and provide a theoretical basis for increasing reserves and production and the efficient development of subsequent fields.
