本文利用方程分析法,结合工程判断,推导出一套模拟蒸汽驱的相似准则。以此为依据,建成了真空物理模拟实验装置。以克拉玛依油田六东二区和九区两个区块为原型,制作了比例模型,进行了模型试验。这两个区块油藏的共同特点是,原油属中等粘度,油层的有效厚度较薄。模拟试验对于蒸汽注入速度、注入蒸汽干度、射孔位置、油藏含油饱和度的影响进行了研究。 In this paper, we use equation analysis and engineering judgment to deduce a set of similar criteria for simulating steam flooding. Based on this, built a vacuum physical simulation experimental device. Based on the two blocks of the second east and the west of the Karamay Oilfield, two models of the model were built and the model tests were carried out. The common feature of these two block reservoirs is that the crude oil is of medium viscosity and the effective thickness of the reservoir is thin. The effects of steam injection speed, steam injection dryness, perforation location and oil saturation of oil reservoir were studied in the simulation experiment.
