摘要: With the success of Bakken tight oil (tight sandstone and shale oil) Eagle Ford in North America, has become a research focus petroleum geology. In China, reservoirs are predominantly distributed lacustrine basins. The Triassic Chang 6 Member is main production layer Ordos Basin, which episodes, timing, drive charging have been analyzed through petrography, fluorescence micro-spectrometry, micro-thermometry, trapping pressure simulations fluid inclusions reservoir beds. Several conclusions reached this paper. First, aqueous with five peaks homogenization temperatures three occurred mostly fractures that cut across occur within quartz grains, overgrowth calcite cements, feldspar ...
