摘要
介绍了一种新的油井水泥缓凝剂JZR-Ⅱ的合成,实验考察了合成条件对产物性能的影响,评价了加有JZR-Ⅱ的G级油井水泥浆的性能,室内实验结果表明:JZR-Ⅱ对G级油井水泥具有优良的缓凝性能,与分散剂、降滤失剂相容性好,对油井水泥的选择性小,适用于井温75℃~180℃的油气井固井作业。
JZR Ⅱ is a newly developed set retarder for oilwell cement slurries, the effect of synthetic condition on product properties was examined.The performance of JZR Ⅱ in grade G cement slurries are evaluated in laboratory .It is shown that JZR Ⅱhave good retarding ability to oilwell cement slurries ,is compatible with the dispersants, filtrate loss controller and relevant to grade G oilwell cement of various manufactures and can be used in cementing process in the range of 75 ℃ ̄180 ℃.
