The physical chemical conditions of oil gas migration in the Kuqa foreland basin were studied with fluid geology method in this paper. Based on section observation and petrology study, were analyzed the homogenization temperature, salinity, Laser Raman spectra, chromatogram and chromatogram spectrography of fluid inclusions, from which were obtained the paleo geotemperatures, salinities, single organic inlusion components, organic components and biomarker parameters of inclusion groups. The sequences, pathway, phase state, temperature, depth, organic components, biomarkers, water medium conditions of oil gas migration and the abundance of migratory concentration in the Kuqa foreland basin were analyzed.
