| 摘 要： | 目前江苏省杨家坝油田已进入高含水阶段且非均质性严重.为了满足油田开发后期的需要,并进一步改善油田开发效果,达到提高原油采收率的目的,需要精细描述单砂体储层的平面非均质性,研究平面非均质性对油田开发效果的影响.利用杨家坝油田的渗透率数据计算了不同层(重点按照沉积微相类型)变差函数的变程.通过变程反映变量的影响范围,对不同...

| Abstract: | Yangjiaba Oilfield exploration has entered the high water stage with serious heterogeneity.To meet the needs of the later development and further improvement of its development effect so as to enhance oil recovery,it is necessary to describe in detail the plane heterogeneity of the single sand reservoir layer and research the effect of the plane heterogeneity.In this paper,Yangjiaba Oilfield is taken as an example for the calculation of the range of variogram in different layers(mostly according to the sedi... |
