摘　　要：概述了煤储层的物性特点,增透改造的发展历程,裂缝起裂、扩展、延伸等研究进展;介绍了国内外压裂装备现状,列举了国内主要产品;分析了重复、多层、薄层、通道、水力喷射逐层、体积压裂等新技术的特点;阐述了压裂液污染环境的形式。建议发展环保、区域化水力压裂技术,装备朝着国产化、自主创新型发展,争取使用清洁、环保型压裂液。The paper summarizes physical characteristics of coal reservoir, development history of permeability-increasing transformation, and progress made in crack initiation, propagation and extension.It introduces current situation of fracturing equipment at home and abroad and lists main domestic products.and analyzes characteristics of new technologies like repetition, multilayer, lamina, passageway, layer-by-layer hydraulic jet and volume fracturing.The paper also elaborates the way fracturing fluid pollutes the environment. It is suggested to develop environment-friendly and regionalized hydraulic fracturing technologies, make equipment developed in a way of localization and independent innovation and use clean and environment friendly fracturing fluid as far as possible.
