摘要：

针对胍胶压裂液胍胶用量偏高及现有有机硼交联剂交联时间调控难、耐温耐剪切性不佳等问题，以硼砂、乙二醇、三乙醇胺和葡萄糖为原料，在碱性条件下经一步法合成了适用于低浓度胍胶的有机硼交联剂BBS。通过单因素与正交试验优化合成条件，借助FT-IR表征产物结构，并系统对比评价了BBS与0.2%胍胶溶液形成的交联冻胶的综合性能，与现场交联剂JL-9进行对比。结果表明，BBS较优配方（质量分数）为硼砂25.3%、三乙醇胺25.3%、葡萄糖14.2%、乙二醇19.7%、氢氧化钠1.1%和蒸馏水14.4%，在50 ℃反应时间4 h条件下冻胶的黏度达72 mPa·s；FT-IR证实产物中形成了氮硼杂环笼状结构；BBS交联冻胶的延迟交联、耐温耐剪切、滤失控制及低残渣破胶性能均优于JL-9；在胍胶基液pH=10、胍胶与交联剂质量比100∶0.4条件下，体系交联时间为264 s，冻胶黏度可达66 mPa·s。BBS中多种硼酸酯可协同实现B （OH） 4-的逐级释放，赋予体系延迟交联、稳黏及抗高温剪切的阶梯流变调控能力，在深井高温压裂中具有良好的应用前景。

Abstract:

At present, the usage amount of guar gum in guar gum fracturing fluids is relatively high, and the existing organic boron crosslinkers are poor in controllability of crosslinking time and inadequate in temperature and shear resistance. To solve these problems, in this work, an organic boron crosslinker （BBS） suitable for low-concentration guar gum was synthesized by one-pot method under alkaline conditions by using borax, ethylene glycol, triethanolamine and glucose as raw materials. The synthesis conditions were optimized by single-factor and orthogonal experiments, and the product structure was characterized by FT-IR. The comprehensive performance of the crosslinked gel formed by BBS with 0.2% guar gum solution was evaluated and compared with that of a commercial crosslinker JL-9. The results showed that the optimized formulation （in mass fractions） of BBS was determined as 25.3% borax, 25.3% triethanolamine, 14.2% glucose, 19.7% ethylene glycol, 1.1% NaOH and 14.4% distilled water. Under the conditions of a reaction time of 4 h at 50 ℃, the apparent viscosity of the crosslinked gel reached 72 mPa·s. FT-IR analysis confirmed the formation of nitrogen-boron heterocyclic cage-like structure in the product. The BBS-crosslinked gel exhibited superior performance compared to JL-9 in delayed crosslinking, temperature and shear resistance, filtration loss control, and rapid gel breaking with low residue. At pH of 10 and the guar gum-to-crosslinker mass ratio of 100∶0.4, the crosslinking time was 264 s, and the gel viscosity reached 66 mPa·s. The synergistic effect of several borate esters in BBS enabled the stepwise release of active B （OH） 4-, endowing the system with delayed crosslinking, viscosity maintenance, and high-temperature shear resistance, which demonstrated promising application prospects in deep and high-temperature fracturing operations.
