Meanwhile, it discusses the pattern cycle water injection rate and effect of cyclic water flooding in the pilot in western area of Fuyu Oil Field.

同时，结合扶余油田西区矿场实例对周期注水的注水方式、周期、注水量及效果进行了探讨。对裂缝性砂岩油藏实施周期注水具有重要的借鉴意义。

Concurrently analyzed is that improvement of effective thermal efficiency after rise in compression ratio and water injection is resulted from thermal efficiency promotion of fuel-air ideal cycle.

同时分析了提高压缩比并掺水蒸气后有效热效率提高的主要来源是燃料—空气理想循环热效率的提高。
