大型稠油油藏整体数值模拟方法

文章介绍了NUMSIP模型软件的分块计算和区域分解并行计算功能,提供了一套大型整装油藏整体注蒸汽热采数值模拟的方法,包括整理数据、建立模型、拟合代表块确定基础参数、分块计算和整体并行计算等过程。并用该方法研究欢喜岭油田齐40块莲Ⅱ油藏剩余油分布。研究表明,利用NUMSIP模拟软件进行大型整装油藏整体注蒸汽热采模拟的方法已基本成熟,利用该方法可以通过拟合整个油藏的动态历史来获得当前剩余油分布,并且可信度高、费用相对较低,为剩余油的研究开辟了新的途径,对指导生产具有实际意义。

Bulky numerical simulation of large scale heavy oil reservoir

Here not only demonstrates the parallel computing functions of NUMSIP model, i.e. block calculation and regional segregation, but present a set of numerical simulation method for large scale and bulky reservoir, including data arranging, model building, typical block match to determine basic parameters, individual block calculation, bulky parallel calculation and so on. Application of this method in studying residual oil contained in Lian II formation, Huanxiling oilfield shows it is almost mature in utilizing NUMSIP software for modeling the development bulky reservoir with steam drive. Residual oil distribution can be understood through dynamic history match by using this method with high reliability and lower cost. Moreover, it has opened new way for residual oil study and possessed great significance for guiding production.
