摘要: 针对我国老油田井网密度大及存在井间干扰的情况,根据井间流线方程的特征,提出了井间干扰条件下PEBI网格划分算法。将此网格下的计算结果与细网格、一般粗网格的计算结果的比较结果表明,反映流动特征的井间干扰网格既能减少计算时间,又能达到和精细网格相近的计算精度。

Abstract: Considering well spacing density and inter-well interference in some old oilfields of China,an algorithm for dividing PEBI grid of oil wells was proposed on the basis of the streamline equation.The stimulation results of PEBI grid were compared with that of the fine grid and the other coarse grids,which indicated that PEBI grid could reduce the computing time and also achieve the same accuracy as the fine grid.

Key words: inter-well interference, PEBI grid, grid division, numerical well testing, computation method
