Study on the Remaining Oil Distribution with Domain Decomposition Simulation Method

Abstract:

Block 127 reservoir was a typical heavy oil reservoir with normal pressure system, high density and viscosity. The block was low production because formation water invaded seriously. Well condition and effects of measure were badly year after year. In order to clarify remaining oil distribution rule, east and west typical well group of block in 127 was chosen. Careful research in typical well group and multiple well group synthesis research method was used to research with numerical simulation method. The sub-zone sand body residual oil saturation chorizo-gram of well groups and entire block were mapped, qualitative and quantity analysis residual oil distribution rule was studied on plane and vertical. The larger and more complex structure reservoir, used to Domain decomposition method with the typical well group fine research, multi-well-group integrated research method is feasible. The knowledge of residual oil is made deeply and these works offer technique support for block heavy oil reservoir.
