储层孔隙介质气体吸附理论模型的研究是以单组分气体吸附模型的研究为基础的。在对 9个化工领域常见的单组分气体吸附理论模型进行再研究的基础上 ,利用储层孔隙介质单组分气体等温吸附数据 ,采用Leven berg Marquardt非线性最小二乘法 ,针对每个模型进行回归拟合计算 ,得到每个模型的模型参数值 ,再将这些模型参数代回到该模型中进行吸附预测。获得的结果是 :单组分气体吸附WilsonVSM模型和FHVSM模型计算值比其它模型更接近实验数据。这表明空穴溶液模型在一定程度上反映了储层孔隙介质单组分气体吸附体系的吸附特征
The theoretical model of gas adsorption in porous media is based on the study of one-component gas adsorption model. On the basis of revisiting the theoretical model of single component gas adsorption common to nine chemical fields, using the Levenberg-Marquardt nonlinear least squares method, one-component gas isothermal adsorption data of reservoir pore media was used for each model Regression fit calculation, get the model parameter values of each model, and then replace the model parameters back to the model for adsorption prediction. The results obtained are: single-component gas adsorption WilsonVSM model and FHVSM model calculated values closer to the experimental data than other models. This indicates that the hole solution model to some extent reflects the adsorption characteristics of the porous media single-component gas adsorption system
