新型纳米材料在现代压裂中的应用

Application of New Nanometer Material in Modern Fracturing Operation

水力压裂是低渗透储藏经济开发的常用手段,也是非常规油气高效开发的必要措施。目前的非常规油气压裂措施工艺中,由于作业级数增加、工艺复杂化和井下环境及介质的变化等因素,对材料的各项要求大大提高。为了解决这一系列要求,基于国外纳米技术,简述了新型纳米材料在现代压裂中的应用:由纳米颗粒研制出的表面活性剂压裂液、纳米减阻剂用于减阻水的重复利用,一种纳米结构的可控电解金属(CEM)压裂球。研究表明,纳米材料逐渐在现代压裂中发挥着越来越大的作用。

Hydrofraeture is a common means of economic development of low--permeability reservoir and also a necessary measure for efficient development of unconventional oil and gas. The current unconventional oil--gas fracturing measure process comes up with higher demands for materials due to such factors as increase of fracturing series, more complicated technology and the change of downhole environment and medium. Based on nanotechnology abroad, this paper discusses the application of new nanometer material in modern fracturing operation, for example, developed surfactant fracturing fluid and nanometer drag reduction agent made from nano--particles and a nano--structure controllable electrolytic metal fracturing ball.
