Abstract
Reservoir simulation has always been an important supporting technology for efficient oilfield development. Daqing Oilfield is an integrated multi-layer sandstone reservoir, which has the characteristics of large oil-bearing area, long development history and many oil and water wells. Due to the limitation of reservoir simulation capability, the scale of models for reservoir simulation research in the past has been around one million nodes, with a maximum of three million nodes. The research objects are mainly development units divided by well rows or closed faults. In recent years, through the development and innovation of the linear solution method, a distributed parallel reservoir simulation technology with a simulation scale exceeding 10 million nodes has been formed. The simulated area is expanded from the development unit to the entire development area, and refined into the layer by the deposition unit. Applying this technology, a fine reservoir simulation study of one development area and two development units has been completed. Through the quantitative analysis of oil saturation and remaining movable reserves at the end of development, it is clarified that the fault edge is the main occurrence parts of the remaining oil in the late ultra-high water cut stage. It also provides theoretical basis and technical reference for the measures to tap the potential of such remaining oil.
