According to dynamic and static data of steam flood test area in Daqing Chaoyanggou oil field, the geologic model controlled by facies is built, then numerical simulation research using STARS module of software CMG is progressed. When the mean permeability is 1 × 10-3 μm2,2 × 10-3 μm2,5 × 10-3 μm2,8 × 10-3 μ m2,10 × 10 -3 μm2 ,15 × 10-3 μm2 ,30 × 10 -3 μm2, the steam flooding effect is researched respectively. The results indicate that the low limit of permeability is 10 × 10-3 μm2 under the condition of water flooding turning steam flooding. The development effect of class three block is the worst under the condition of continuous steam injection flooding. Continuous steam injection flooding is only used in class one block and class two block of Chaoyanggou oil field.%根据现场提供的朝阳沟油田蒸汽驱试验区的动、静态数据,首先用Petrel软件建立试验区相控地质模型,然后应用CMG软件中的STARS模块进行数值模拟.研究了地层平均渗透分别为1×10-3 μm2、2×10-3 μm2、5×10-3 μm2、8× 10-3 μm2、10×10-3 μm2、15×10-3 μm2、30×10-3 μm2七种方案进行蒸汽驱开采时,蒸汽驱的受效规律.结果表明:水驱油藏转蒸汽驱开发的渗透率下限值为10×10-3 μm2.采用连续注蒸汽驱三类区块开发效果最差,连续注蒸汽驱开发仅适用于朝阳沟油田的一类及二类区块.
