摘要
本文在三维Marchuk分数步长算法的基础上,提出了多组分模型中求解非线性方程组的分数步长算法格式。通过在K值多组分模型中应用此算法对凝析气藏进行模拟计算,表明其结果合理、精度高、工作量少,其模拟时间仅为状态方程型多组分模型的1/25左右。
Based on the three dimension 'Marchuk' fractional steplength algorithm, the format of the fractional steplength al- gorithm for solving nonlinearity equation groups in multi-component model is presented in this paper. Through the simu- lation calculation of condensate gas pool using this method in K-value multi-component model, it is indicated that the re- suit is reasonable, and has high precision and little man-hours, and the simulation time is only about 1/25 of the multi- component model of state equation type.
