摘要
针对复杂断块油藏数值模拟模型中出现的构造变形、地层接触关系不对、断层两侧断距不对、毛厚度/有效厚度不合理以及参数调整后出现的"马赛克"现象,文中提出了相应的模型修正方法。该方法在中原油田的马厂、胡状等复杂断块油藏应用后,减小了数值模拟历史拟合误差,大大提高了剩余油研究精度,取得较好的挖潜效果。
A corresponding improved method is adapted in numerical simulation to the fault block oilfield aimed at the tectonization, the wrong contact relationship between formations,the wrong fault throw beside the faults, the unreasonable ratio of the gross thickness and the effect thickness and the mosaic phenomenon after adjusting the coefficients. The improved method achieves better effects and improves the simulation results greatly when used in the numerical simulation in the complex fault block reservoir in Zhongyuan Oilfield.
