①储集层物性纳米级实验分析技术投入应用。一项数字岩石物理技术——基于高分辨率纳米CT扫描系统与FIB扫描电镜的一种纳米级实验方法,具有超高分辨率和三维可视化展示等特点,其可对致密储集层微观孔喉结构进行无损伤立体重构、确定孔隙分布特征与储集层参数,揭示流体渗流机理与油气成藏过程。它通过多尺度岩心扫描确定孔隙度、渗透率、孔喉连通指数与储集层力学性质的相关参数,并利用晶格玻尔兹曼原理模拟油气渗流机理,建立基于真实三维孔隙模型的非常规油气成藏动态模型。②致密油开发关键技术突破实现工
① reservoir physical properties of nanoscale experimental analysis technology into use. A digital petrophysical technique - a nanoscale experimental method based on a high-resolution nano-CT scanning system and a FIB scanning electron microscope with ultra-high resolution and three-dimensional visualization and other characteristics, which can be used for micro-pore throat Structure without damage three-dimensional reconstruction to determine the pore distribution characteristics and reservoir parameters to reveal the fluid percolation mechanism and hydrocarbon accumulation process. It determines the parameters of porosity, permeability, connectivity index of pore-throat and mechanical properties of reservoirs by multi-scale core scanning. The mechanism of oil-gas seepage is modeled by lattice Boltzmann principle, and the unconventional three-dimensional pore model is established Dynamic model of hydrocarbon accumulation. ② key technologies for the development of tight oil breakthrough work
