摘要： 对复杂交叉断层合理的网格化是建立复杂断块油藏及不规则边界油藏的地质模型的关键环节,以往的建模软件将断层沿网格处理为台阶式,在不规则油藏的边界则通过变形角点网格来处理,在一定程度上降低了模型的精度,为此,利用HOT 公司的SURE 模拟软件对吐哈油田部分断块油藏进行了地质建模及数值模拟研究,较合理地处理了复杂交叉断层,使三维地质模型中断层周围网格块的参数合理分布,提高了对断块油藏模拟的精度。

Abstract: The rational gridding of complicated cross faults is the key of geologic modeling and simulation of complex fault block reservoirs and irregular-boundary reservoirs. In previous modeling software the faults are processed as staircase along the grid, while the boundary of an irregular reservoir is dealt with by deformed angular point grid, which decrease the accuracy of the model to a certain extent. By using SURE software developed by HOT company, this paper conducts the geologic modeling and numerical simulation for partial fault blocks in Tuha oil field, and more rationally deals with the complicated cross faults, realizing reasonable distribution of the grid block parameter around faults in the 3D geological model, and increasing the accuracy of fault block reservoir simulation.

Key words: Tuha basin, fault block reservoir, perpendicular bisection grid technique, geologic modeling, reservoir simulation
