【摘要】：阳离子清洁压裂液是以阳离子黏弹性表面活性剂为主剂的水基压裂液,具有配制简单、不需要交联剂、只需要加入表面活性剂和稳定剂、返排迅速且彻底、伤害低、携砂性好、滤失控制性能好等特点。由于对环保问题的日益重视,与压裂液相关的环保、高效的阳离子清洁压裂液的研究开发成为压裂液发展的重要方向。但随着国内外各油田打井深度的不断加深,对阳离子清洁压裂液的性能要求也变得越来越高,尤其是阳离子清洁压裂液的耐温性能。因此对其耐温性的改良一直是研究的重点。本文介绍了国内外现有的阳离子清洁压裂液的体系组成、耐温性研究现状及应用情况,提出提高耐温耐剪切性能是阳离子清洁压裂液的主要发展方向。对清洁压裂液阳离子体系今后的发展提出建议,以期为相关研究提供借鉴和参考。
[Abstract]:Cationic clean fracturing fluid is a water-based fracturing fluid with cationic viscoelastic surfactant as the main agent. It has the advantages of simple preparation, no need of crosslinking agent, only adding surfactant and stabilizer, quick and thorough back discharge, low damage and good sand carrying ability. The performance of filtration control is good. Due to the increasing attention to environmental protection, the research and development of high efficiency cationic clean fracturing fluid related to fracturing fluid has become an important direction of fracturing fluid development. However, with the deepening of drilling depth in various oilfields at home and abroad, the performance requirements of cationic clean fracturing fluid become more and more high, especially the temperature resistance of cationic clean fracturing fluid. Therefore, the improvement of its temperature tolerance has been the focus of research. This paper introduces the system composition, research status and application of cationic clean fracturing fluid at home and abroad, and points out that the main developing direction of cationic clean fracturing fluid is to improve its temperature and shear resistance. Suggestions for the future development of clean fracturing fluid cationic system are put forward in order to provide reference and reference for related research.
