Abstract: Measures of enhancement recovery are discussed based on the analysis of the high rate of increase of our crude oil output and the development of wells of high output and zones with high rate of production.It is pointed out that the general trend of our oil field development in the last thirty years is one of gradual intensification and that to keep a sustained high rate of production through regulation of output between pays,wells and zones conforms to the oil-water movement in highly heterogeneous multizone oil fields.Therefore,it is predicted that enhancement recovery shall remain an important approach to tap our oil potential in forthcoming years.
