摘　　要：安塞油田为典型的低渗、低压、低产油藏,由于长6储层微裂缝发育,注入水突进,水驱效率低,严重影响油田的开发效果。为此,试验应用了弱凝胶增注调剖技术,一方面解决了调剖剂注入困难问题,另一方面有效地改善了注水剖面,对应油井增油降水显著,为特低渗油田的高效开发探索出了新的途径。Ansai production. Due saltation, the oil Oilfield is typical of low permeability, low formation pressure, and to the development of microcrack in chang6 oil reservoir, and injected production in chang6 reservoir is low. Therefore, the weak gel profile minor water control technique was tested in Ansai Oilfield. The technique resolved the problem of injection of profile control agent. At the same time, it could improve water entry profile. The results indicated that the technique is effective in low permeability oilfield.
