【摘要】：本文简述了水基压裂液体系中常用交联剂(无机/有机钛、锆、硼等)的化学结构和性能特点;重点介绍了有机硼交联剂在羟丙基瓜胶水基压裂液体系的交联机理、技术指标和现场应用情况;从交联剂的结构、有机配体的分子组成、交联性能、交联剂制备路线等方面阐释了交联性能是由配位中心的性质、基液pH、配体的配位能力、稠化剂的种类和用量等因素共同决定的。同时回顾了交联剂理论研究进展和现场应用现状,并对水基压裂液交联剂在极端条件、性能指标、复合体系及经济性等应用方向进行了展望。
[Abstract]:In this paper, the chemical structure and properties of common crosslinking agents (inorganic / organic titanium, zirconium, boron, etc.) in water-based fracturing fluid system are briefly described, and the crosslinking mechanism of organoboron crosslinking agent in hydroxypropyl melon glue based fracturing fluid system is emphatically introduced. The structure of crosslinking agent, the molecular composition of organic ligand, the crosslinking property, the preparation route of crosslinking agent and so on, the properties of coordination center, the pH of base solution and the coordination ability of ligand were explained. The type and dosage of thickener are determined together. At the same time, the research progress of crosslinking agent theory and the present situation of field application are reviewed, and the application direction of water based fracturing fluid crosslinking agent in extreme conditions, performance index, composite system and economy are prospected.
