由于油藏数值模拟在油田开发中具有十分重要的意义,本文以CK油田C42井区为例,对C42井区进行数值模拟研究。本文对C42井区建立了数值模型,经历史拟合后,分析了C42井区的油水运动规律,得出剩余油分布特点为:在没有注水或注水井数少的区域为主要的剩余油分布区域,其特征表现为大面积连片分布;在注水区的部分井组仍然富含剩余油,其特征表现为形态各异并连片沟通的分布;纵向上剩余油分布形态基本相似。
Since reservoir numerical simulation is of great significance in oilfield development, this paper takes C42 well in CK Oilfield as an example to study the numerical simulation of C42 well. In this paper, a numerical model was established for C42 well. After history fitting, the oil-water movement law in C42 well area was analyzed, and the remaining oil distribution was characterized as follows: the remaining oil distribution in the areas without or with a few water injection wells Area, characterized by large area contiguous distribution; some well groups in the waterflooding area are still rich in residual oil, which is characterized by the distribution of various forms and contiguous communication; the remaining oil distribution in the longitudinal direction is basically similar.
