Basic features of petroleum exploration development in mature exploration area

The cooperation of exploration processes of several accumulation systems leads to the periodicity of petroleum-bearing basin exploration.When reserve growth continues between different accumulation systems,exploration develops.Preliminary exploration,rational reserve sequence and resource replacing capacity are required so as to make progress in mature exploration region.An exploration unit is the smallest geologic unit in which exploration can be arranged and carried out.The subdivision of exploration unit is the symbol for deepen-ing development in mature region.New ideas are important for new discoveries.The adequate protection of resources,the stable development of exploration teams and the harmony of inner and outer environments are the keys for the constant increasing of reserves.The studies of mature region exploration may provide guides for exploration arrangements and strategic researches.
