摘要:
为认识页岩油储集层岩石中流体的流动规律,以准噶尔盆地吉木萨尔凹陷芦草沟组为例,利用室内物理实验和数字岩心技术,开展了页岩油储集层微观孔隙结构和渗流机理研究。通过页岩油岩心单相渗流物理实验,获得基于启动压力梯度的单相渗流非线性数学模型以及与孔隙结构特征参数相关的渗透率经验公式;基于数字岩心,利用格子玻尔兹曼方法,进行页岩油单相流体的模拟,实现流体流动的精细表征。结果表明,页岩油储集层的渗流速度与压力梯度关系具有典型的非达西渗流特征,呈三次函数关系,具有非常好的相关性。
Abstract:
To understand the rules of flow in shale oil reservoir, taking the Lucaogou formation of Jimsar sag in Junggar basin as an example, the micro-pore structures and flow mechanism of the shale oil reservoir were studied by means of laboratory physical experiments and digital core technology. Based on the physical experiment of single-phase flow through shale oil cores, a non-linear mathematical model of single-phase flow based on starting pressure gradient and an empirical formula of permeability related to pore structure parameters were obtained. Digital core technology and Lattice Boltzmann method were used to simulate the single-phase fluid of shale oil and to realize the fine characterization of fluid flow. The results show that the relation between seepage velocity and pressure gradient in the shale oil reservoir has a typical non-darcy flow characteristic, which is a cubic function relation with a good correlation.
