Discussion on hot spots in petroleum geology

With the deepening and extension of exploration activities,the theories of petroleum geology need to be further examined in many aspects.Some problems and their brief analyses are presented facing some current issues of general interest,including theories about the formation of high-altitude reservoirs,development and challenges of non-marine petroleum geology,types of potential reservoir and exploration area(stratigraphic-lithological traps),and attributes of natural gas formation and distribution.The formation and preservation of high-altitude reservoirs are subject to rigorous condition restraints.Continental petroleum geology has many unclear and unresolved problems in the principle of petroleum accumulation in deep zone as well as the matching of petroleum accumulation.Stratigraphic-lithological reservoirs are getting more important with the deepening of basin exploration.Natural gas provinces are separately distributed and possess attributes specific to themselves.
