Oil well cement retarder as well as preparation method and application thereof
The invention discloses an oil well cement retarder as well as a preparation method and application thereof. The oil well cement retarder is prepared from the following raw materials: a reinforcing agent, a stabilizing agent, tartaric acid, sodium glucoheptonate, sodium gluconate and deionized water. The oil well cement retarder is applicable to the temperature range of 100-180 DEG C, can meet the strength requirement of a large temperature difference of 80 DEG C, and can solve the problems that a high-temperature retarder is poor in temperature resistance, the dosage has no linear relation, the strength development of top set cement is slow, and industrialization is difficult.
本发明公开了一种油井水泥缓凝剂及其制备方法和应用。本发明的油井水泥缓凝剂的制备原料包括：增强剂、稳定剂、酒石酸、葡庚糖酸钠、葡萄糖酸钠和去离子水。该油井水泥缓凝剂适用温度范围为100～180℃，能够适应80℃较大温差的强度需求，能够解决高温缓凝剂耐温能力差、加量没有线性关系、顶部水泥石强度发展缓慢和工业化困难的问题。
