大庆油田榆树林区块为特低渗透区块,榆树林采油厂近年来推广CO2单井吞吐工艺来提高原油采收率.针对榆树林油田CO2吞吐施工井的选择方法展开研究,将模糊数学评判方法应用于CO2吞吐井位选择.榆树林油田CO2吞吐井位的选择应考虑下面6种参数:剩余油饱和度、油井含水率、油层厚度、渗透率、孔隙度、井底流压.
Yushulin block of Daqing oilfield is low permeable block. Yushulin oil production factory is popularizing carbon dioxide stimulation to improved recovery. Optimization research of carbon dioxide stimulation in Yushulin oil production factory, and introducing fuzzy mathematics in well choosing of carbon dioxide stimulation be well chosen. Six factors in chossing well of carbon dioxide stimulation in Yushulin oil production factory be should consider, such as remainder oil saturation, water content ratio, reservoir thickness, permeability, porosity, bottom hole flowing pressure.
