The key factors for CBM reservoir adsorption gas desorption rate are pore radius、saturated gas content、Network size seam fracturing of communication and expand nanometer pore and seam、gel breaking in time、fracturing fluid residue can be Timely flowed back、continuous drainage gas recovery in a timely manner、group well for a long time constant drainage、often remove of the pulverized coal clogging.First,in nanometer center well fracturing,using the Dissolving and the corrosion,Communication cracks and expand the throat,enlarge the nanometer pore and seam,communication native hole seam,carrier and Made seam,formed Cracks network, improve the desorption speed,improve the seepage velocity.Second,timely flowback.Third,continuous drainage and Gas recovery.Fourth,all Wells of the development area can be fractured with nano fracturing.Fifth,dissolve Pulverized coal and flowback pulverized coal in a timely manner,In the whole production process.Low cost industrial production of coalbed methane will inevitably lead to low cost industrial production of shale gas,other adsorption gas,adsorption oil,ultra dense and low permeability oil and gas.

自上个世纪末纳米科技被引入地质学以来,国内外地质学家在矿物学、地球化学、构造地质学以及矿床学等领域开展了与纳米颗粒相关的研究,取得了一系列的成果和认识(孙岩等,2009;De Paola,2013;Siman-Tov et al.,2013;琚宜文等,2016).新生代以来以来，红河断裂带经历了早期(古近纪)的大型左旋走滑运动和后期(新近纪以来)的右旋走滑运动（向宏发等，2004），断裂带宽30-
目前多项先进技术和方法已广泛应用于非常规致密储层纳米孔隙结构精细表征,主要包括扫描电镜分析技术、纳米CT扫描技术、核磁共振技术,压汞分析法、气体吸附法等(邹才能,2013;卢双舫,2016).其中,气体吸附法是研究连通纳米孔隙形态、比表面积及孔径分布的重要技术手段.矿物作为岩石基本组成单元，对纯矿物纳米孔隙结构的研究是不可或缺的一部分，对于查明储层纳米孔隙特征及其控制因素提供重要依据。本文采用低温
Nanoparticles are particles between 1 and 100 nanometers in size,and in effect a bridge between bulk materials and atomic or molecular structures.
常规的测试技术主要测试微米级的孔隙而泥页岩的孔隙从纳米级到微米级均有分布,因此常规的测试技术难以准确的表征泥页岩的微观孔隙结构,引入氮气吸附法对泥页岩的纳米孔隙进行分析,可以弥补常规测试技术的不足.研究表明泥页岩的孔隙既包括两端开口的圆柱形孔、四边开放的平行板结构的狭缝型孔,又含有墨水瓶孔、锥形管孔、锥形结构的狭缝孔以及一端开口的圆柱孔;孔径多分布在18nm以下,微孔具有较强的吸附聚气能力,构成了
断裂构造演化的核心问题,尤其是在时空转化上的稳定性判识,是确定其弱化作用(weakening)及其机制(Reches et al.,2010).近些年来,对各种岩石不同断裂于狭窄滑移面中,所形成的断裂弱化作用研究取得了迅速的发展,与其相关的天然观察、实验测试和理论分析,不仅在宏观和微观层面上,也在超微观和纳观尺度上都已广泛地展开了(Nada et al.,2005;Moore et al.,200
Nanostructural parameters of four bituminous coals from central Nepal were determined by attenuated total reflection Fourier transform infra-red spectroscopy(ATR–FTIR),X-ray diffraction,high resolutio
Numerous studies have been reported recently on nanometric amorphous silica materials.For instance,mesoporous silica(e.g.,FSM-16 and MCM-41) is expected to use as a selective catalyst for chemical rea
地震化石假玄武玻璃,又称假熔岩(林爱明,2008),被认为是断层带内地震发生的直接证据.而另一更为众人熟知的是断层产物—断层泥,沿着阿尔金断裂、富蕴断裂、海原断裂、北川-映秀断裂、鲜水河断裂、安丘-莒县断裂等重大断裂内都发育断层泥.如,汶川5.12大地震地表主滑动面可见到强烈变形的薄层断层泥(袁仁茂等,2014);安丘-莒县断裂多个剖面可见到颜色丰富的断层泥条带;台湾集集地震车笼埔断裂也发育断层泥
Clay minerals are the important components of source rocks,and the catalysis effect of clay minerals as an important factor for hydrocarbon generation has been realized for a long time.
