本文对辽河、长庆和胜利油田75个油藏最小含油喉道半径(rhmln)及储油指数(β)进行了计算。并对其在油藏评价中的应用进行了讨论。这些应用是:(1) 根据储油指数进行油藏分类;(2) 研究油水分布,用rhmln和毛管压力曲线确定原始含油饱和度;(3)根据原始含油饱和度所确定的rhnln值计算油藏中的油柱高度。结果表明,储油指数可以作为油藏分类标准。根据rhmln确定的原始含油饱和度较一般毛管压力曲线方法确定的含油饱和度更准确。
In this paper, the minimum oil throat radius (rhmln) and oil storage index (β) of 75 reservoirs in Liaohe, Changqing and Shengli oil fields were calculated. And its application in reservoir evaluation is discussed. These applications are: (1) reservoir classification based on oil storage index; (2) study of oil-water distribution, determination of original oil saturation with rhmln and capillary pressure curves; (3) calculation of oil from rhnln values determined from original oil saturation Hidden oil column height. The results show that the oil storage index can be used as a reservoir classification standard. The original oil saturation determined by rhmln is more accurate than the oil saturation determined by the general capillary pressure curve method.
