摘要
运用黑油数值模型对特低渗透有底水的油气田的开采井网密度进行了探讨,并结合某油田的油层参 数和物理实验得出了井网密度为20-25口／km2为宜,运算结果指出,类似储层的采收率一般为45％左右,无水期 为3～6个月,研究结果对类似储层的开采方案具有一定指导作用。
The paper discussed the production pattern arrangement in ultra low permeability oil & gas field with bottom water by using black oil numerical model, and combining with the reservoir parameter and physical experiment, obtained the suited pattern density (20 - 25 wells/km2). Through calculation, the results showed recovery efficiency of similar reservoir was about 45% , water - free period was 36 months. The research result has certain directive function for recovery scheme of similar reservoir.
