TAKING A VIGOROUS ACTION TO EXPLORATION OF INORGANIC-SOURCED HYDROCARBON

There may be much more hydrocarbon in inorganic-sourced domain than in organic-sourced domain.Conditions for accumulation of inorganic-sourced hydrocarbon are as follows: (1)large deep fault to lithosphere as migration path; and (2)the hydrocarbon was not oxidated in process of migrating to crust surface. The accumulation pattern was suggested in accordance with above conditions and lithospheric structure: (1) traps in rift system or rift basin with thick sediments of reducing environment, which mixed with organic hydrocarbon; and (2) residuals of lifted horizontal zone of fracture neighbering rift basin. The prospects of inorganic hydrocarbon and their exploration method were indicated.
