　　One of the most complex topics in reservoir characterization is the estimation of pore-fluid content away from well locations.The unconventional reservoirs in Sulige gas field（Ordos Basin,North China）face this problem of having high heterogeneity,low pressure,low permeability,and low gas richness features.Sand bodies are widely distributed and most of them are adjacent to each other,but the hydrocarbon presence is scattered.Thus,the challenge in the Lower Permian Shihezi Formation（LPSF）,which is...
