本文利用逾渗网络模型在大庆长垣以西地区葡萄花油层组进行了储层特性(孔隙连通性、孔喉比、地层水矿化度、粘土含量及微孔隙含量)对岩石电阻率影响的模拟。在模拟中考虑了不同孔渗条件下储层岩石电性特征的变化。模拟结果表明,在大庆长垣以西地区葡萄花油层组喉道半径、孔隙连通性、孔喉比、地层水矿化度、粘土含量及微孔隙含量6种因素都对储层岩石电阻率具有较大的影响。
In this paper, we use the percolation network model to simulate the influence of reservoir properties (pore connectivity, pore-throat ratio, formation water salinity, clay content and micropore content) on the resistivity of the Putaohua reservoir in the west of Daqing Changyuan. . In the simulation, the change of electrical characteristics of reservoir rock under different pore and permeability conditions was considered. The simulation results show that there are six factors affecting the rock resistivity of the reservoir: the throat radius, pore connectivity, pore throat ratio, formation water salinity, clay content and microporosity in the Putaohua reservoir of the west of Daqing Changyuan Big impact
