When used as the fluid loss agent for oil well cement, it is difficult for polyvinyl alcohol (PVA) to form even complex gel with the mixing inorganic salt in temperature lower than 40 ℃ ; while in higher temperature,(>100 ℃), the complex gel is easily decomposable, thus the range of cross-linked PVA is relatively narrow.
作为油井水泥降失水剂,聚乙烯醇(PVA)和共混的无机盐在较低温度下(<40℃)难形成均匀的络合物胶,在较高温度下(>100℃)络合物胶又易分解,因此共混交联PVA的适用温度范围较窄。
