The use of specific synthetic polymers as oil well cement filtrate reducer has recently drawn a wide attention in industry.
目前在油井水泥降失水剂领域,合成聚合物降失水剂再度成为研究的热点和重点。
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。
