摘要/Abstract

摘要： 本文采用状态方程混合型算法对柯克亚凝析气藏进行了相平衡计算。采用加速迭代法、插值法代替逐步迭代法;用一个近似矩阵代替梯度型算法不易实现的Jacobi矩阵的逆矩阵。计算结杲表明,这种方法具有计算速度快,稳定性好的优点。

Abstract: The phase equilibrium calculation of Kekeya condensate pool has been made using a hybrid method of the equation of state. That is accelerated iteration and interpolation in place of iteration step by step, of which a similar matrix has been adopted rather than a reverse one of Jacobi' s matrix that could hardly allow for giving solution with gradient method. The result shows that this method has advantages of fastly calculating speed and fairly good stabilities.
