摘　　要：针对钻井液降滤失剂在使用过程中存在的高温增粘和遇到金属离子污染增粘的问题 ,从降滤失剂的分子结构出发 ,通过苯氧 (基 )乙酸与苯酚、甲醛等缩聚磺化 ,合成出磺化苯酚 /苯氧 (基 )乙酸 /甲醛树脂 (简称 SPX树脂 )。试验研究表明 ,SPX树脂单独使用就具有抗饱和盐抗高温非增粘降滤失量的作用 ,含盐量在 2 5%～ 36%之间时降滤失效果良好 ,含盐量低于 2 5%时延长老化时间也有良好的降滤失效果 ;在加量合理时 ,钻井液老化前后表观粘度增加率小于 1 0 %。 SPX树脂与 SMK。In consideration of increasing viscosity in filtrate reducer in drilling fluid under the conditions of high temperature and high contamination from metallic ions, sulphonate phenol and phenoxyacetic acid formaldehyde resin (simply call it SPX resin) is synthesized through polymerization and sulphonating using phenoxyacetic acid, phenol, formaldehyde etc. The result shows that when the SPX resin is used independently, it has the properties of high temperature resistance and saturated salt resistence for non-viscosified filtrate reducer and good efficiency of filtrate reducing. When salt content is from 25% to 36%, the filtrate reduction efficiency is the best, when the content is below 25%, it is the best for lengthening aging time; when the content of SPX is reasonable, the apparent viscosity increase of the drilling fluid is less than 10% before and after its aging. The combination of SPX with SMK and SKC is good.
