摘要
以S油藏为研究对象,应用数值模拟、油藏工程等方法对厚层块状超稠油油藏蒸汽吞吐后期转换开发方式进行研究。研究结果表明,该油藏适合火驱辅助重力泄油开发,先导试验井组已取得预期效果,预计最终采收率达到58.0%,较吞吐开发提高采收率33.2%。该项研究成果对同类油藏吞吐后期大幅度提高采收率提供了借鉴。
Taking S reservoir as a research object,this paper focuses on the study upon the replacing development method at late stage of steam stimulation in thick block extra-heavy oil Reservoir,using numerical simulation.The result shows that this method is suitable for S reservoir and the result from Pilot Test has demonstrated its advantages.The estimated oil recovery is 58.0%,which increases 33.2% compared which steam stimulation.The results of this study bears high reference value for similar reservoirs at late stage of steam stimulation.
