摘  要:大港油田固井施工中广泛使用氯化钙作早强促凝剂。针对氯化钙的缺点,研制了由多种组分组成的新型油井水泥早强促凝剂DZEOS。本文报道DZEOS的组成、研制、早强促凝性能、水泥浆性能、与大港油田常用降滤失剂WO1的配伍性,介绍了在4口井固井中的应用效果。etting accelerator DZEOS for oilwell cement is developed to replace CaCl_2 and composed of 3 main ingredients: WG, an alkalitreated fly ash; TEA, a Mannichs reaction product of diethanolamine, CH_2O etc; SJX, a partially hydrolyzed AA/AM/VAc copolymer, with some amounts of thinner FDN and filtrate reducer S24 added. The functions of main ingredients, single and in pair, the setting promoting and early strengthening properties of cement slurries with DZEOS introduced, the compatibility of DZEOS with WO1, a commonly used filtrate reducer in Dagang, are investigated. A comparison between these two accelerators is also made. The trial use of DZEOS in cement slurries for 4 cementing operations is successful.
