摘要
应用三甲基硅烷化(TMS)技术,对常温(93℃)和高温(160℃)下掺有NaCl的G级油井水泥浆固化过程中水化产物(SiO_4)^(4^-)四面体聚合态结构与抗压强度的关系进行了分析。结果表明,国产G级油井水泥在93℃和160℃下,当其在8h相对左右龄期具有较多的活性单体时,水泥石强度也相应较高,NaCl浓度为15％时,水泥石的8h龄期强度比NaCl浓度为0％和36％时的水泥石同龄期强度大。指出TMS技术,同样可以用活性单体含量的变化,对在其它应用条件下可能导致G级油井水泥性能变化的因素作出一定的解释。
The relation between compression strength and tetrahedral configuration (SiO4) formed in the solidification process after adding sodium chloride to cement slurry is analysed in the temperature condition of 93 ℃ and 160℃ by using trimethyl silanization technology (TMS) . Tests indicate that the cement possesses good compression strength while adding sodium chloride for 8 hours. also the compression strength of cement with the concentration of 15% sodium chloride is higher than that of cement with the concentration of 0% and 36% sodium chloride.
