降滤失剂作为重要的钻井液处理剂，其耐温耐盐能力直接影响水基钻井液的性能。从聚合物结构和官能团出发，选用对苯乙烯磺酸钠（SSS ）、丙烯酰胺（AM ）、烯丙基聚乙二醇（APEG）进行共聚得到钻井液降滤失剂KJC。以失水量为评价指标，通过单因素实验得到最佳合成条件为：m（APEG）∶ m（AM ）∶ m（SSS）＝1∶2∶1，单体质量分数20％，反应温度60℃，引发剂质量分数0．7％，反应时间5h。通过红外分析表明，合成产物结构与设计结构相符。性能评价表明，所合成的聚合物具有较好的抗温能力和抗钙能力。

As an important drilling fluid ,the ability of heat resistance and salt tolerance of flu-id loss additive directly affects the performance of w ater-based drilling fluid .Based on the poly-mer structure and functional groups ,drilling fluid loss additive KJC was obtained by copolymeri-zing sodium styrene sulfonate (SSS) ,acrylamide (AM ) ,and allyl polyethylene glycol (APEG) . Taking the water loss as an evaluation index ,the optimal synthesis conditions were gotten by sin-gle factor experiments ,namely m(APEG)∶ m(AM )∶ m(SSS)=1∶2∶1 ,monomer mass con-centration is 20% ,reaction temperature is 60 ℃ ,initiator dosage is 0 .7% ,and reaction time is 5 h .The FT-IR spectrum analysis shows that the product structure is consistent with design struc-ture synthesis .Performance evaluation shows that the synthetic polymer has good temperature resistance and the ability to resist calcium .
