| 摘 要： | 为在室内测量和解释非均质岩石渗透率，根据全岩芯分析装置的测试试验数据和描述流体非均质介质中一维不稳定渗透的数学模型，建立了计算非均质储油气岩石渗透率的自动拟合模型，并利用伴随函数和伴随方程计算目标函数的梯度，采用逐步二次规划法求解自动拟合模型，最后，通过算例说明了该方法的可行性和可靠性。

| Abstract: | For measuring and analyzing the permeability of inhomogeneous reservoir rock in laboratory,an automatic fitting model is built to calculate the permeability of inhomogeneous reservoir rock based on the test data of whole core analysis and the mathematical model describing unsteady flow in one-dimensional inhomogeneous porous medium. The gradient of objective function is calculated by means of adjoining function and the auto-match model is solved by sequential quadratic programming methods. The feasibility and reliability of the method are proved by examples. |
