摘要： 研制了一种复合型无氯油井水泥早强剂L L, 采用复配的方法将有机酸D、 醇胺类物质E和硝酸盐F
按一定比例复配, 利用正交试验设计以水泥石6h的抗压强度为考察指标优选试验配比。通过正交试验确定早强剂
L L最佳配比为: 有机酸D质量分数为1. 0%( 占水泥质量) , 醇胺类物质E质量分数为0. 0 4%, 硝酸盐F质量分数为
4%。在最佳配比下, 加入早强剂的质量为水泥质量的2. 5%, 结果表明, 加入早强剂L L的水泥浆稠化时间与水泥净
浆稠化时间之比为0. 4 3 6, 小于0. 5、 水泥石6h抗压强度( 3 9曟、 常压) 为1 1. 0MP a, 大于4. 0MP a, 满足早强剂行业
标准S Y / T 5 0 0 4. 4—2 0 0 8的相关要求。与自制缓凝剂 MAM、 分散剂F A S A及降失水剂 A S等有良好的相容性。

Abstract: A chlorinefree composite as oilwell cement early strength agent named LL was developed. Combining organic acids A, alcohol amines B and nitrate compound C in a certain ratio, the compressive of cement stone in 6 h as the strength examining index can be designed in optimization test using the orthogonal method. The optimum formula determined by orthogonal was as follows: the weight of organic acids D is 1.0% based on cement，the weight of alcohols amines E is 0.04%，the weight of nitrates F is 4%. Under the optimum proportion, and the performance test of early strength agent LL was carried out after its addition of 2.5% in the cement. The ratio of the thickening time of early strength agent LL slurry to cement slurry is 0.436 less than 0.5, and the compressive strength of cement stone 6 h (39 ℃ and atmospheric pressure) is 11.0 MPa more than 4.0 MPa, they are all meeting the requirement of early strength agent industry standard SY/T5504.4—2008. And it has a good compatibility with the homemade retarders MAM, dispersants FASA and fluid loss AS.
