The statistics of 36 oilfield steam drive pilot test results show that the oil-steam ratio depends on not only the reservoir parameters, but also the steam injection rate.

国外36个蒸汽驱现场试验结果统计规律表明，蒸汽驱油汽比不仅与地质参数有关，而且与注汽速度密切相关。

The study shows that cyclic steam injection rate, soaking time, flowing bottom hole pressure and blowdown mode are important factors influencing the effectiveness of single well steam stimulation.

分析认为，周期注气量、注气速度、浸泡时间和生产过程中的井底流压及降压方式都是影响单井吞吐效果的重要因素。
