A Method for the Automatic History Matching of Single Well Black Oil Model

提出了单井三维三相黑油模型自动历史拟合的一种方法。在此基础上，建立了一个带约束条件的非线性目标函数，应用本算法使目标函数达到最小，实现自动历史拟合，从而反求出地层各参数值，另外还对新疆百口泉井的测试资料进行了自动历史拟合，求得了各自地层参数值，同时将本文结果与地层参数电测解释结果进行了对比，证实了本算法求解的可靠性。

A method for the automatic history matching of a 3-dimentional and 3-phase single well black oil model is presented in this paper, and a non-linear objective function with restraints is set up on the basis of this method, which can be used to minimize the objective function and achieve automatic history matching, thus obtaining the parametric values of the formation. In addition, an automatic history matching is made for the data of a well in Baikouquan,Xinjiang and the parametric values of the formation are obtained. At the same time, the parametric values of the formation are compared with the electrometric interpretation results and the results obtained by this method prove to be reliable.
