摘要/Abstract

摘要： 格子玻尔兹曼方法以其能够处理复杂几何边界，在数字岩心多孔介质流动模拟中被广泛应用。以渤海S油田东营组储层数字岩心切片为研究对象，在图像处理基础上，运用格子玻尔兹曼方法开展二维孔隙流动模拟及速度场表征，通过改变模拟条件，分析不同生产压差、孔喉优化对切片渗流通道的影响。结果表明，生产压差仅能改变各通道的渗流速度；岩石孔径是影响渗流通道分布的主要因素；孔喉优化能够有效调整渗流通道,提高微观孔隙波及程度。

Abstract: The lattice Boltzmann method is widely used in the simulation of digital core porous media flow because it can handle complex geometric boundaries.The digital core section of the Dongying formation reservoir in the Bohai S oilfield is taken as the research object. Based on the image processing, the lattice Boltzmann method is used to carry out the two⁃dimensional pore flow simulation and velocity field characterization. By changing the simulation conditions, the different production pressure differences are analyzed. The effect of pore throat optimization on the slice seepage channel. The results show that the production pressure difference can only change the seepage strength of each channel. The rock pore size is the main factor affecting the distribution of the seepage channel. The pore throat optimization can effectively adjust the seepage channel and improve the microscopic pore wave degree.

Key words: Digital core, Lattice Boltzmann method, Flow simulation, Seepage channel
