Abstract: The frequency of layer supplementing and layer exchanging is used to ensure the stable oil-gas output,since the tension of petroleum production supply during the multi layered reservoir development.This behavior led to the bad effects for later potentiality exploitation of reservoir and scheme adjustment.There are the efficient and effective methods in site practice,such as comprehensively analyzing well logging interpretation data,dynamic production data.They can provide the references for in site worker.Here,we point out the splitting method of oil and gas production in multiple completion wells of multi layered reservoir in combination with comprehensively analyzing well logging interpretation data,dynamic production data.It's helpful to find out residual resources and guide potentiality exploitation measure.

Key words: Multi layered reservoir, Commingled production, Tapping potential, Production split
