摘要
本文以有机硼交联剂和羟丙基胍胶的交联反应为基础,选择了影响该反应过程的六个主控因素——有机硼活化能Ea、温度、pH、有机硼交联剂浓度、羟丙基胍胶浓度以及时间t,通过中心法则实验设计,建立了这六个因素与冻胶170 s?1剪切粘度的数学模型。该模型的建立对有机硼交联剂的研制、压裂体系的构建、压裂液性能评价和预测,压裂施工条件的优化均具有重要的实际意义。
Based on cross linking reaction of organic boric cross-linker and hydroxypropyl guar gum, central composite experimental design is used to construct a mathematic model of guar gel viscosity with the key factors. Six key factors, including the organic boron activation energy (Ea), temperature (T), pH value, organic boric cross-linker, concentration, hydroxypropyl guanidine gum concentration, and time (t), were chosen for the study. The model could thereafter contribute to the development of organic boric cross-linker, construction of fracturing system, prediction and evaluation of the fracturing fluid;it also has important practical significance for the optimization of fracturing execution conditions.
