Oil and Gas Geological Exploration Enteringa New Era from the Source Rock Era to the Mantle Source Oil Era
The history of petroleum exploration is briefly reviewed,and the exploration data of 25 oil fields(basins or oil areas)at home and abroad are analyzed and studied.Then it is concluded that the first stage of petroleum geological exploration is anticlinal(structural)exploration(from 1860s to 1960s),the second stage is source rock exploration(from 1930s to now),and now it has entered a new stage-mantle source oil and gas exploration era.According to the theory of mantle-derived oil and gas,an innovative"basin-crust-mantle mirror superimposed reservoir formation model"is proposed.
