| 摘 要： | 由于富台潜山油藏埋藏深、储层基质孔隙度及渗透率较低、非均质性强,油层普遍存在污染堵塞,自然产能较低。在分析油藏地质及试油特征的基础上,进行了酸液溶蚀率、降阻剂及缓蚀剂等评价,提出了胶凝稠化酸体系和多级注入闭合酸化、压裂改造工艺,措施井11口,有效井9口,有效率达81.8％。

| Abstract: | cause of deep buried depth, low porosity and low permeability of reservoir matrix, and severe heterogeneity in Futai buried-hill oil reservoir, pollution blockage appears in oil-bearing formations and natural productivity is low. Based on the analysis of the characteristics of reservoir geology and formation testing, the dissolution rate of acid solution, friction reducer and anti-corrosive agent are evaluated, and jollification viscous acid system and multistage input closed acidiza tion fracturing reformation technology are proposed. 9 out of 11 oil wells taken measures are effective, that is, the efficiency is 81.8%. |
