YYCM堵水堵漏剂的研究与应用

ＹＹＣＭ复合堵水堵漏剂是一种非选择性无机复合速凝堵水堵漏剂。文章介绍了ＹＹＣＭ的组成，在室内对ＹＹＣＭ成份的含量进行了试验， 同时对ＹＹＣＭ的性能进行了评价，ＹＹＣＭ具有封堵可靠、速凝、强度高、热稳定性好和有效期长等优点，对于封堵套漏失、串槽具有较好的作用。在室内试验的基础上，１９９８年以来在９口油水井的应用工艺成功率达１００％，到１９９８年底已累积增油３１４５t，取得了较好的效果，满足了油田高含水期堵水的需要，是油田高含水期控水稳油，实施油田稳产的主要手段之一。

The Study on YYCM Water Blockoff- plugging Agent and Its Application

YYCM compound water blockoff-plugging agent is a inorganic accelerator agent with nonselectivity.The paper introduces forms of YYCM agent.Meanwhile,the performance of YYCM agent is evaluated .It has many advantages,such as dependable plugging, quick solidification,high strength,good thermal stability and long valid period.IT has better effect on plugging casing leak and channelling .Based on studying in lab and applying in 9 wells in 1998,the results show that YYCM plugging success ratio is 100%,accumulated increased oil is 3145t by the end of 1998.YYCM agent can meet the needs of water plugging of figh water cut stage .IT is one of the main means of stable production.
