Abstract:
It has been shown through organic geochemical study that there existfour oil--generating strata:lower Cambrian black grey shales, Permian darkgrey organic limestones and black grey shales, middle Triassic Leikoupoformation dolomites, and Upper Triassic Xu jiahe formation grey blackmudstones and coal beds in the overthrust nappe and its leading edge.Re--servoirs in the area are characterized by low porosity, low permeability,intensive structural damage and poor oil一preserving conditions, but they are still favourable for finding structural or lithostructural oil and gas pools inweakly pressed, completely preserved structures in the frontal zone, suchas the downblock of the south-eastern flank of Tian jinshan anticline,Feng-shunchang protruding anticline.
