    產品介紹


     磺化酚醛樹脂-磺化褐煤是磺化酚醛樹脂和磺化褐煤的共聚物,為黃色至棕色的粉末。它是一種抗高溫降濾失劑,配成溶液后不僅可以有效的降低濾失并形成高質量的泥餅,而且在高溫下也能在長時間和鉆很長的進尺后使鉆井液性能性能保持穩定。SPNH與KPAM、SMP,SMC SMT配合使用形成磺酸鹽鉆井液體系可以用于鉆超過4000m的深井,還用于配制鹽水飽和鹽水鉆井液。SPNH抗溫能力為180℃。SPNH在淡水鉆井液中加量為1%~2%,在鹽水鉆井液中的加量為2~3%。

    SPNH SPNH is a copolymer of sulfonates of phenol resin,lignite and acrylic polymer.It is a yellow to brown powder.SPNH is a high temperature FL control agent. The fluid system treated with a certain amount of SPNH not only gets a very well controlled FL and a high quality of mud cake,but also renders the system a stability of longer period and more footage at higher temperature. SPNH jointly used with KPAM,SMP,SMC and SMT can formulate polymer-sulfonates drilling fluid systems for wells of depth over 5000m and also salt water and saturated water drilling fluid systems. The thermal stability of SPNH itself is about 180℃.The routine dosage of SPNH is 1%~2% for fresh water drilling fluid and 2~3% for salt water drilling fluid
