Retarder and preparation method thereof
The invention discloses a retarder which comprises a hydroxy carboxylic acid, organic phosphonic acid and inorganic micromolecular phosphoric acid, so that the upper limit of the applicable temperature of a cement paste system taking a liquid suspending agent as a lightening agent is expanded to 150 DEG C, the application range of the cement paste system is further expanded, and the cement paste system can be used as technical casing pipe leading paste. Therefore, safe and efficient deepwater well cementation operation is achieved.
本申请公开了一种缓凝剂,所述缓凝剂包括羟基羧酸、有机膦酸和无机小分子磷酸,使以液体悬浮剂为减轻剂的水泥浆体系适用温度上限扩大至150℃,进一步扩大该水泥浆体系适用范围,使其可以作为技术套管领浆使用,从而实现安全高效深水固井作业。
