油井水泥降失水剂AS的合成与性能评价OA
Synthesis and Evaluation of AS Fluid Loss Additive for Cement Slurry
采用自由基聚合法,以2-丙烯酰胺基-2- 甲基丙磺酸(AMPS)和丙烯酰胺(AM)为原料合成共聚物,再与木质素磺酸钠复配,合成了降失水剂 AS.通过正交试验优选合成条件,并对降失水剂AS进行了全面的性能评价.评价结果表明:降失水剂AS具有较好的耐热性和耐盐性,在150℃下,降失水剂AS在饱和盐水中的API滤失量(API滤失量,即按API标准测量的失水量,简称滤失量)为96 mL;在120℃下,水泥中单独掺入质量分数3％～8％的聚合物可将滤失…查看全部>>
The AS fluid loss additive was formulated with sodium lignosulfonate and the copolymers obtained by radica polymerization with AMPS and AM as raw material. Orthogonal tests were designed for optimizing the synthetic process of tin fluid loss additive AS, and the performance of this fluid loss additive was systematically evaluated. API filtration in saturate! Salt solution at 150 ℃ is 96 ml,; APT filtration can be controlled within 50 ml. When adding AS betwe…查看全部>>
