基于正交设计方法的蒸汽吞吐参数优化

Optimization of Steam Huff and Puff Parameters Based on Orthogonal Test Method

稠油油藏在蒸汽吞吐开发阶段,注汽量、注汽速度、焖井时间、产液速度、蒸汽干度等注汽参数很大程度影响着其开发效果。在取得较好的历史拟合结果后,根据油藏实际生产资料,确定参数取值范围,利用正交设计方法全面考虑不同注汽参数组合下的预测结果,优选出最佳参数组合,为油田生产提供指导。

Steam injection parameters,such as steam injection volume,steam injection rate,its soak time,production rate, steam quality and so on,affect the result in the steam huff and puff period,data range is obtained according to actual production data obtained after history matching,prediction result is gained by taking fully consideration of different compositions of parameters based on orthogonal test method,the best combination is obtained,it provides guidance for the actual production.
