摘要
利用XRD和SEM-EDS对胶乳油井水泥水化产物及硬化浆体微结构进行了研究。结果表明胶乳并没有改变油井水泥水化产物的种类;微观形貌显示,胶乳的掺入使得水化产物表面形成一层绒状的物质结构,堆积紧密的六方叠片状的Ca(OH)2晶体形貌变得松散薄片状分布。
The microstructure and hydration products of latex oil well cement pastes were investigated by means of XRD and SEM-EDS. The results show that adding latex doesn’ t change the type of hydration products of oil well cement. The morphology shows that a layer of fluffy material is formed on the surface of hydration products due to the incorporation of latex. The calcium hydroxide crystal, which is hexagonal plate-like and accumulates tightly in hardened neat cement paste, becomes looser and laminar in the hardened latex oil well cement paste.
