摘要
从辽河稠油的地质条件和开发状况出发，在总结前人研究成果的同时，以油藏工程理论为基础，提出了计算已开发蒸汽吞吐油藏原油采收率的五种方法。可惜鉴这些方法用于系统合理地确定稠油蒸汽吞吐阶段的原油采收率。
ive methods have been put forward to calculate oil recovery in developed reservoirs bycyclic steam injection,based on the geological conditions and development status in Liaoheheavy oil fields,and the summarization of previous studies as well as reservoir engineeringtheories.Three methods can be used to systematically and reasonably determine oil recoveryof heavy oil in the cyclic period.
