摘要
方法在物理模拟的基础上，利用数值模拟及油藏工程方法，对影响火烧油层的技术参数进行了优选研究，并对影响火驱成败的油藏地质参数、注气参数进行了分析。目的寻找适合庙５块低渗透稠油油藏的开采方法。结果提出了庙５块火驱的最佳开采方式、点火参数及注气参数；庙５块火驱生产后，平均单井日产液由０１ｔ上升到５６ｔ，平均单井日产油由０１ｔ上升到３５ｔ，生产２６ｄ后由于压风机供风不足被迫停止火驱注气；从数模结果看：火驱最终采收率可达３９８％。结论火烧油层是一种潜力很大的稠油开采方法，但其物理、化学反应机理复杂，火烧前缘难以控制；庙５块火驱初期虽然见到了一定的生产效果。
MethodOptimization of those technical parameters that influence in-situ combustion and
analysis the geological, injection-production parameters that are vital for in-situ combustion by
way of numerical simulation and reservoir engineering method based upon physical simulation.
PurposeTo find method which is suitable for the development of low permeability heavy oil
reservoir of Miao-5 fault block.ResultOptimised recovery method of in-situ combustion of Miao-5
fault block is found accompanied with ignition parameter and gas injection parameter. Daily
liquid production is increased from 0.1t to 5.6 t after conducting in-situ combustion while that of
oil is increased from 0.1t to 3.5t. It was stopped due to inefficiency of air compressor after 26
days continuous production. From the result of numerical simulation, ultimate recovery factor
can be as high as 39.8%.ConclusionIn-situ combustion is a heavy oil recovery method with
large potential. However, the physical and chemical reaction are complex and the combustion
front bank is hard to control. Production effect is seen at initial stage of combustion in Miao-5
fault block but with no economical benefit.
