数值试井方法研究

Study on the Method of Numerical Well Testing

对于复杂形状、多变的非均质油藏以及多相流等常规试井问题,利用解析方法很难解决,用数值试井的方法可望得到很好的解决。文中提出了数值试井研究的五个主要内容,即参数拟合方法、数值模拟的精度控制、网格剖分技术、与常规试井方法的结合、试井资料的挖潜。同时指出了数值试井的优点与不足。

There is not an universally accepted method to deal with the problems of non homogeneous reservoirs with complicated or variable shapes and well testing of multiphase flow,while,the numerical well test is hopeful. This paper presents five main contents which numerical well test studied,that are parameter matching method,accuracy control of numerical analog,net work split technology,combination with traditional well test methods and how to extend the scope of well test interpretation. It gives out the merits and demerits.
