Evaluation and Analysis of Commonly Used Sulfonated Phenolic Resins

摘要

摘要: 通过红外光谱、浊点盐度和黏均分子量分别验证了SMP-Ⅱ与SMP-Ⅲ的分子基团、抗盐性能和分子量大小。利用电镜扫描分析了2种产品水溶液以及与重晶石作用情况,测试了他们在钻井液中的性能,讨论了他们与黏土和其他处理剂复配后的效果及作用机理。实验结果表明,SMP-Ⅱ、SMP-Ⅲ在基团、抗盐性方面无明显差异,但SMP-Ⅱ的吸附能力较SMP-Ⅲ强;SMP-Ⅲ在单独使用时,高温高压滤失量为17.5 mL,而SMP-Ⅱ与SMC复配后的高温高压滤失量为20 mL;高温和高盐促使SMP-Ⅱ、SMP-Ⅲ自身以及与SMC等处理剂适度交联,形成的大分子聚合物析出后具有很强的护胶能力,能有效吸附黏土颗粒改善泥饼质量,从而达到降失水的效果。同时确定该类产品最优加量为5%。

Abstract: Two commonly used sulfonated phenolic resins, SMP-Ⅱ and SMP-Ⅲ, were tested for their molecular structures, saltresistance, molecular weights, and their capacities in rheology control. SMP-Ⅲ can control the HTHP filter loss of drilling fluid to 17.5 mL, while SMP-Ⅱ, when used with SMC, a sulfonated lignite, can control the HTHP filter loss to 20 mL. High temperature and high salinity push forward the modest crosslinking of SMP-Ⅱ or SMP-Ⅲ itself, or the crosslinking of SMP-Ⅱ(or SMP-Ⅲ) and SMC, producing high molecular weight copolymers that are effective in rheology control. The copolymers, by adsorbing onto the surfaces of clay particles, improve the quality of filter cakes, reducing filtration of drilling fluid. The optimum treatment of SMP-Ⅱ or SMP-Ⅲ is determined to be about 5%.
