摘要
火烧油层是开发稠油油藏的一种有效方式,分析了厚层稠油油藏开采的难点以及蒸汽吞吐后存在的问题,利用现场数据采用CMG软件对火烧油层生产动态过程进行了模拟,建立了厚层稠油油藏火烧油层方式开采情况下的不同布井方案的油藏数值模型,然后依据模拟结果分析火烧油层后的剩余油饱和度、采收率以及空气油比的变化情况,综合考虑各种因素后得出了最优布井方案,结果表明直井排状井网采油效果最好。
In-situ combustion was an effective way for development of heavy oil reservoirs,the difficulty of thick heavy oil reservoir exploitation and problems after steam huff and puff were analyzed,CMG software was used to simulate dynamic production process of in-situ combustion based on field data,different well numerical models were established for in-situ combustion well patterns of thick heavy oil.Based on the simulation results,the in-situ combustion production is analyzed,the residual oil saturation,oil recovery and air-oil ratio changes,optimal well-pattern scheme are obtained by considering various factors,the result shows that vertical well array is the best.
