Salt beds largely and thickly scatter in the North Area of Dongpu Sag, Zhongyuan Oilfield.In order to solve the problems existed in cementing such formations, proposals are put forward that casing string should be designed accord ing to double-axis by BEB Company of former West German and collapse-strength of casing string is increased. By using saturated salt-water slurry,salt-resisting cement slurry additives and oil-base spacer,etc.,cementing quality has been improved.In 30 wells with salt beds,cementing quality of all wells is up to standard, and 75% high grade.

Cement slurry additives including accelerater, retarder filtrate-loss reduction additive, anti-gasmigration agent, dispersant, expansion agent, anti-strength retrogression agent, free water contorl and solid suspending agents, and clay control agent, etc. have developed in different degree in the 90's. The retarder, filtrate loss reduction additive, and anti-gas migration agent have further improvement, specially synthetic polymer products are main developing direction abroad. From the early 90's, the development of cement slurry additives has been valued at home, some of them, such as filtrate loss reduction additive etc. has obtained great achievement. But as compared with abroad, there is a bigger disparity in application. Based on the analytical result of the situation and developing trends, five suggestion points are given to the future delopment of cement slurry additives.

本文综述了国内外油井水泥添加剂,包括促凝早强剂、缓凝剂、降失水剂、防气窜剂、分散剂、膨胀剂、水泥石强度提高及抗衰退添加剂、游离水控制和固体悬浮调节剂、粘土控制剂等,在90年代均有不同程度的发展。国外在缓凝剂、降失水剂、防气窜剂等方面进展较大,特别是合成聚合物类产品成为发展主流。中国国内自90年代初高度重视水泥添加剂的发展,以降失水剂为代表的一些剂种获得了丰硕成果,但推广应用与国外尚有较大差距。根据对国内外油井水泥添加剂现状与发展趋势分析提出了5点建议。
