复杂断块油藏Delaunay三角网格自动剖分技术

The automatic dissected technology of Delaunay triangular grids for complex fault - block oil reservoir

以平面散点集逐点插入Delaunay三角化的方法为基础,根据复杂断块油藏数值试井计算精度的要求,在布点和三角化过程中采用一定策略,将Delaunay三角网格方法改进成一种简单易用且适用于复杂断块油藏数值模拟的三角网格自动剖分方法,编程实现了复杂断块油藏Delaunay三角网格自动剖分技术,根据该技术编写的程序控件成为数值试井软件中的一个高效模块。

Based on the Delaunay triangular method inserted point by point in planar scattered set, Delaunay triangulation method is improved to an automatic dissected method of triangular grids suitable to numerical simulation of the complex fault - block oil reservoir by using certain strategy during dotting and triangulation according to the demands of calculation accuracy o[ numerical well testing in the oil reservoir. The new method may be realized through programming. Program control unit programmed according to the technology has become an efficient module in the well testing software.
