| 摘 要： | 运用模糊数学方法计算非均质综合指数和计算渗透率非均质参数，对胜坨油田坨28断块沙河街组二段储层的非均质性进行了定量研究。结果表明：储层的层间，层内和平面非均质性强，随着开发注水的深入进行，非均质性有减弱趋势，但减弱幅度不大；各小层及其韵律层在不同开发时期的非均质程度有明显的差异。沉积微相控制储层非均质程度；成岩作用使非均质性复杂化；注采井网不完善，加剧了非均质性的差异性。研究成果在剩余油挖潜的应用中起到重要作用。 |

| Abstract: | Study of reservoir heterogeneity plays an important role in the exploration and development stages of oilfield, especially in the later stage of development. With the method of fuzzy mathematics to calculate heterogeneous synthetic index and permeability heterogeneity parameter, we conducted a quantitative study to invesrigate the second member of the Shahejie Formation, Tuo 28 fault block of Shengtuo Oilfield. The results suggested that the heterogeneities of interlayer, internal and plane are strong in the reservior beds. However as the development of further waterflood, the heterogeneity shows a trend of reducing but the range of reduction is small and the heterogeneous degree of each substratum and rhythmic unit is apparently different in various stages of development. Sedimentary microfacies controls the heterogeneous degree, diagenesis makes heterogeneity complicated and the deficient injection and production pattern increases the heterogeneity in evidence. The results of study have good effects in increasing production of well bed, well pattern adjustment, new well drilling and bring great economic benefits. |
