摘要
详细地叙述了混相驱提高原油采收率室内实验研究所进行的压力一组分实验、细管实验和长岩心驱替实验。通过室内实验筛选了注入溶剂，确定了在一定实验条件下注入溶剂与地层原油形成混相的最小混相压力或最小混相富化量，获取了注入溶剂在岩心驱替过程中的驱油效率和动态特征等方面的重要成果。
Laboratory studies of pressure composition(P-C), slim tube and core flood are described indetail for miscible enhanced oil recovery in Wendong oilfield.Injection solvents are chosen from P-C studies. The minimum miscibility pressure (MMP) or the amount of enrichment is determined by slim tube tests. The displacement efficietncies and flood performance are obtained from core flood tests.
