利用数值模拟技术 ,分别研究了具有物性和岩性夹层 (包括单个和多个夹层 )的稠油油藏对水平压裂辅助蒸汽驱开采效果的影响。模拟结果表明 :油藏中夹层的存在对开采不一定是不利因素 ;注汽井打开程度不同对开采有夹层的稠油油藏有一定的影响 ;开采过程中 ,注汽井打开程度的确定依夹层的类型及分布范围而定 Using numerical simulation techniques, the effects of heavy oil reservoirs with physical properties and lithologic intercalations (including single and multiple intercalations) on horizontal fracturing auxiliary steam flooding were studied. The simulation results show that the existence of interlayer in the reservoir is not unfavorable to the mining; the different degree of opening of the steam injection well has some influence on the exploitation of the heavy oil reservoir with interlayer; in the mining process, the opening degree of the steam injection well depends on Depending on the type and distribution of the interlayer
