摘要

胍胶压裂液是目前压裂作业中应用最多的工作液

但存在胍胶用量高、残渣量大、储层伤害严重的问题。有机硼交联剂因交联性能优异、延迟交联易调控、压裂液破胶彻底、可降低胍胶用量、减少胍胶残渣对储层的伤害

是目前胍胶压裂液体系交联剂的主要研究方向。文章介绍了胍胶压裂液体系有机硼交联剂的研究进展

探讨了有机硼交联剂的交联作用机理

重点总结了有机硼交联剂的合成研究情况

在此基础上对今后发展方向进行了展望。从合成研究情况来看

有机硼交联剂主要有多种配体复合制备、长链多头极性有机胺硼制备、纳米交联剂制备三种方式

在降低胍胶用量、提高压裂液携砂性能方面表现优异。今后研究中应以提高交联效率为关键

长链多头极性结构是主要研究方向

有机配体的优选和反应设计将是研究的核心问题。

Abstract

Guar gum fracturing fluid is the most widely used working fluid in fracturing operation at present

but it has the problems of high dosage of guar gum

large residue and serious reservoir damage. Organic boron crosslinking agent is the main research direction of crosslinking agent of guar gum fracturing fluid system because of its excellent crosslinking performance

easy regulation of delayed crosslinking

complete gel breaking of fracturing fluid

reducing guar gum dosage and reducing reservoir damage caused by guar gum residue. This paper introduces the research progress of organic boron crosslinking agent in guar gum fracturing fluid system

discusses the crosslinking mechanism of organic boron crosslinking agent

focuses on the synthesis of organic boron crosslinking agent

and prospects the development direction. From the synthesis research

the organic boron crosslinking agent mainly has three methods: the composite preparation of various ligands

the preparation of long-chain multi head polar organic amine boron and the preparation of nano crosslinking agent

which has excellent performance in reducing the amount of guar gum and improving the sand carrying performance of fracturing fluid. In the future research

the key is to improve the crosslinking efficiency. The long-chain multi head polar structure is the main research direction. The optimization of organic ligands and reaction design will be the core problems.
