摘　　要：通过对基团作用机理的分析,选用丙烯酰胺(AM)、二甲基二烯丙基氯化铵(DMDAAC)、耐温抗盐单体(SUA)和酯(ZL)进行四元共聚合成出了新型钻井液降滤失剂JLS-1。经过对影响JLS-1性能的各因素进行实验研究,得到合成降滤失剂JLS-1的最佳条件。同时分别在淡水基浆和盐水基浆中对降滤失剂JLS-1的性能进行了评价,实验结果表明,降滤失剂JLS-1在淡水基浆和复合盐水基浆中的API滤失量分别为6.2 mL(加量为1.0%)和7.1 mL(加量为2.5%),并且具有较好的抗温能力,抗温达120℃;该降滤失剂还具有一定的防膨效果,防膨率可达73.8%。A drilling fluid filter loss reducer JLS-1 was developed by copolymerization reaction of AM,a high temperature salt-tolerant monomer SUA,DMDAAC and an ester ZL.The optimum synthesis condition and the performance evaluation were performed through laboratory research.A fresh water base drilling fluid treated with JLS-1(concentration 1.0%) had a filter loss of 6.2 mL and a composite saltwater drilling fluid(concentration 2.5%) had a filter loss of 7.1 mL.JLS-1 functions well at 120℃.Core swelling is reduced to 73.8%with JSL-1 solution.
