介绍了克拉玛依油田稠油蒸汽吞吐开采中使用的一种水泥堵剂、一种膨润土水泥堵剂的配方、应用性能及一种可固化的改性沥青 C9 树脂反应产物的应用。该有机复合树脂可用作水泥、膨润土水泥堵剂的添加成分,也可用作两种无机颗粒段塞之后的封口段塞。这几种堵剂常温粘度低,利于泵注;滤失量小,利于深部封堵;凝结时间长,利于施工;在克拉玛依油田六区、九区12 口蒸汽吞吐稠油井用于调剖取得成功,效果显著。
A kind of cement plugging agent used in heavy oil steam huff and puff in Karamay Oilfield, the formula of a kind of bentonite cement plugging agent, the application performance and the application of a kind of curable reaction product of modified asphalt C9 resin were introduced. The organic composite resin can be used as an additive for cement and bentonite cement plugging agents, and can also be used as a sealing slug after slugging of two inorganic particles. These types of plugging agent have low viscosity at room temperature, which is good for pump injection; small amount of filtrate loss is conducive to deep plugging; long setting time, which is good for construction; 12 oil steam stimulation heavy oil wells in six districts and nine districts of Karamay Oilfield are used for profile control success , The effect is remarkable.
