摘　　要：压裂是非常规和海上低渗储层最重要的增产改造技术手段,也是中国海油实现“十四五”目标的重要途径。本文调研分析了中国海油煤层气压裂技术、致密气压裂技术和海上低渗储层压裂技术原理、工艺特点、应用效果、存在问题,并从煤层气适应性压裂增产技术、致密气降本增效压裂技术、地质工程一体化技术、压裂船装备等技术领域展望了中国海油压裂技术发展方向,以期对中国海油非常规和海上低渗储层开发技术的进一步发展和完善提供借鉴。Fracturing is the most important stimulation treatment for unconventional and offshore low permeability reservoirs,and it is also an important way for CNOOC to achieve the goals of“the 14th Five-Year Plan”.This paper investigates and analyzes the principles,technological characteristics,application effects,and existing problems of CNOOC’s coal-bed methane fracturing technology,tight gas fracturing technology and offshore low permeability reservoir fracturing technology.In addition,the development direction of CNOOC’s fracturing technology is prospected from technical fields such as adaptive fracturing technology for coal-bed methane wells,cost reduction and efficiency enhancement fracturing technology for tight gas wells,geo-engineering integration technology,and fracturing ship equipment,in order to provide reference for the further development and improvement of CNOOC unconventional and offshore low permeability reservoir development technology.
