摘要
以苯酚、甲醛、亚硫酸钠、二甲胺和１溴丁烷为原料，合成了两性磺化酚醛树脂降滤失剂ＡＰＲ。通过红外光谱对其结构进行了表征。考察了ＡＰＲ 的抗高温抗盐降滤失性能、抑制性及其与两性聚合物重泥浆的配伍性。从研究ＡＰＲ在膨润土上的吸附入手，对其作用机理进行了简要分析。
A novel fluid loss controller for drilling mud, amphoteric sulfonated phenolic resin (APR), was prepared from phenol, formaldehyde, sodium sulfite, dimethylamine, and butyl bromide. The constitution of APR was identified by IR spectrometric data. The fluid loss reducing property of APR in salt clay mud, the inhibiting capacity of APR for clay swelling and the compatibility of APR with a weighted amphoteric polymer(FA367+XY27) mud were investigated and shown to be better than that of commercial sulfomethylated phenolic resin SMP: APR was more temperature resistant and salt tolerent. The adsorption of APR on Na bentonite was also determined as compared with SMP and the mechanisms involved in functioning of APR as mud additive were discussed on the basis of the adsorption data obtained.
