NEW TECHNOLOGICAL ADVANCES IN PETROLEUM EXPLORATION

New analytic technologies in petroleum geological research and exploration activities have made great progress in recent years.Especially there has been a burst in the fluid inclusion study of oil-bearing sequences,which can determine the timing and physical-chemical conditions in the past.Light hydrocarbon analytic methods is making much progress,especially in source rocks.The alkylphenol and benzocarbazole extraction methods are also successful,and the changes in benzocarbazole concentration and the ratio of benzocarbazole can be used to discuss hydrocarbon migration.Also,the analytic method of clay minerals including mixed layer I/S,illite,etc.has developed fast.For example,the crystallinity values of illite are wildly used in the petroleum geological exploration of Songpan region.
