Abstract—In view of offshore conventional heavy oil reservoir, it is characterized by serious interlayer interference, low flooding recovery and difficulty to develop on low permeability layers with the development of large well space and multi-layer commingled. For the purpose of interlayer interference on flooding oilfield development with different standard permeability and permeability ratio, visual physical simulation experiments on dynamic multilayer flooding oil were carried out. The research result show that when the permeability rise, the contribution of high permeability layer significant increase, with the obvious appearance of less oil production of low permeability layer, and the total recovery is significantly decreased. When the permeability ratio rises above 3, the larger contribution of high permeability layer, and the contribution ratio of high and low layers is gradually increased, and the total efficiency is decreased. When the standard permeability is small, which called the permeability value of low layer, the water breakthrough time of high layer is short.
