摘要
酸化压裂改造技术是碳酸盐岩储层和裂缝性砂岩储层增产改造的主导技术,地面交联酸是一种新型的适用于酸化压裂的压裂液体系,但是目前关于地面交联酸体系交联反应特征、耐剪切性能,以及影响因素的研究还不够深入。文中以酚醛树脂和合成有机锆作为交联剂,以盐酸质量分数为20%的稠化剂溶液作为基液,对这两种的地面交联酸体系分别进行了流变学研究,测定了这两种体系在不同交联比下的耐温耐剪切性能,交联过程黏弹性模量随时间的变化,以及不同剪切速率和不同温度下的流变曲线,讨论了交联比、温度、剪切速率对交联反应的影响。并对酚醛树脂和有机锆交联体系进行了对比和分析。研究地面交联酸的流变性质,对于交联酸体系的研发和改进十分重要。
Fracture acidizing has been used as a key way to boost production for carbonate reservoir and sandstone reservoir,in-situ crosslinked acid gel is a new fluid developed for fracture acidizing,.The study for it is not specific however,especially for shear properties,characteristic of crosslinking,and influence factors.Two kinds of gel was studied,which has different crosslinking agent and same polymer solution,phenolic emulsions and organic zirconium are different crosslinking agent,and polymer solution contains 20%(wt)HCl.The shear properties in different Crosslinking ratio,and the changes of viscosity and viscoelastic modulus with time was tested both of the two system.As well as the Rheological curve of under the different shear rates and different temperature.The influence of the Crosslinking ratio,temperature,and shear rates to gel was also investigated at the conclusion.This study is very important for the research of in-situ crosslinked acid gel.
