摘要

摘要: 针对柴达木盆地英东油田长井段油层层间非均质性强、产能差异大、产液能力不确定给低油价下效益开发带来的诸多问题，笔者尝试利用渗流系数、存储系数与含油饱和度作为fisher判别函数参数对研究区不同储层产能进行了定量评价研究。通过实际生产数据与理论函数对比，理论模型整体判别符合率达到80%以上，基本满足了油藏开发需要，为后续油藏的单层砂体投产治理、产能部署及储层预测动用提供了决策依据。

Abstract: In the Changjing section of Yingdong Oilfield, Qaidam Basin,the heterogeneity in interlayers and the uncertain production capacity caused many problems under the circumstances of low price.The authors use seepage coefficient, storage coefficient and oil saturation as the fisher discriminant function to quantitatively evaluatethe reservoir productivity.The conformity rate of the theoretical model is above 80%,compared to the actual production data and the theoretical functions, meeting the need of reservoir development.The research providesa basis for the comprehensive use of monolayer sand body, the deployment of the production capacity and the prediction and utilization of the reservoir.
