摘要/Abstract

摘要： 蒸汽驱及化学辅助蒸汽驱是提高稠油油藏采收率的重要方法。为了对比两种开发方式提高稠油采收率的效果，以新疆塔河油田稠油为研究对象，采用蒸汽驱油模拟实验装置，对比评价了不同开发方式下注汽参数对提高稠油采收率的影响。实验结果表明，蒸汽驱提高稠油采收率与注汽温度正相关，对注入压力不敏感；与蒸汽驱相比，加入一定助剂正戊烷、正己烷、正庚烷，对提高稠油采收率有明显效果；同时发现，蒸汽驱稠油采收率随着注汽压力的增加而趋于降低，化学辅助蒸汽驱稠油采收率随着注汽压力的增大而有所增加。

Abstract: Steam flooding and chemical assisted steam flooding are important EOR methods for heavy oil reservoirs.In order to compare the two methods,we performed simulated steam flooding experiments on samples from Tahe heavy oil reservoirs in Xinjiang,China,to assess their EOR effects under different steam injection parameters.The results show that,during steam flooding,the oil recovery is positively correlated to injection temperature but insensitive to injection pressure,and that adding some additives,such as n-pentane,n-hexane,and n-heptane,can greatly improve the recovery.It is also noteworthy that the recovery factor of heavy oil tends to lower along with increasing injection pressure during steam flooding,while it increases to some extent along with increasing injection pressure during chemical assisted steam flooding.

Key words: additive, steam flooding, assisted steam flooding, recovery factor, heavy oil
