有限元技术在数值试井中的应用

分析了试井技术的发展趋势，对有限元分析技术及其发展作了较为全面的介绍，重点阐述了利用有限元技术进行三维建模的方法和步骤，尤其是对复杂的非对称边界和非均质油藏的建模方法和技巧进行了深入探讨。利用数值试井技术，石油工程师可以方便准确地对复杂油藏和边界进行建模，试井的模拟过程和油藏任意位置的压力瞬间变化都可以通过图形和颜色的变化显示出来，解释的精度和速度都得到了大大地提高。

Application of the Finite Element Technique in Numerical Value Well Test

This paper analyses the well test technology development trend, fully introduces the finite element analysis technology and its development, expatiates tridimensional modeling method and procedure with finite element technology emphatically. For the most of all, it makes a deepening study in modeling approach and technique of complex asymmetry boundary and anisotropic petroleum reservoir. Using numerical value well test technique, petroleum engineers can do modeling at complex petroleum pool and boundary conveniently and accurately. The instant variety of simulation process in well test and the pressure at any positional in petroleum pool can be shown through the figure and chromatic variance. Precision and rate of interpret has been improved.
