Use reservoir engineering method , differentiated
multistory sandstone reservoir’s development stage by oil
recovery rate of recoverable reserves.Compare it with
production , water-cut or development performance to
differentiated multistory sandstone reservoir’s development
stage ,oil recovery rate of recoverable reserves taper law is
more clearly than others in the whole development
history.test this method with the real datum of Gu-
dong.The applications of the other pilot areas show that the
method is simple and useful.Use this new method ,we foud
most Chinese multistory sandstone reservoir is always high-
speed stable production period.
