    Abstract
  • In the process of the light hydrocarbons in oil or gas reservoirs exchanging substance and energy with surrounding material,all states of light hydrocarbons form a dynamical equilibrium under the action of the surface of sediment.According to the composition and content of physically-absorbed light hydrocarbons,we can trace the source of light hydrocarbons(i.e.oil or gas reservoirs),and further predict or deduce the properties and characteristics of oil or gas reservoirs.By the technology of physically-absorbed light hydrocarbons,the physically-absorbed gas is completely released from the sample in a vacuum state.The light hydrocarbon compositions are analyzed qualitatively and quantitatively with gas-chromatogram.The properties and characteristics of oil or gas reservoirs are determined according to the variety of light hydrocarbon concentration.The technology of physically-absorbed light hydrocarbons got very good application results in Xinchang gas field in Sichuan Basin,Zhenyuan-Jingchuan loes-sial plateau in Ordos Basin and Chaiwopu gobi area in Tarim Basin.This technology has a very good prospect in application and popularization.
