| Abstract: | This paper analyzes the effect and characteristics of such pathway systems as faults,cracks,unconformity and karst in Lower Palaeozoic carbonate in Tazhong area.The bridging and interconnection of faults with the source rocks and reservoir beds led to the vertical migration of oil and gas.While the multi-stage regional unconformity surfaces,network systems of karstified fissures and caves made it feasible for oil and gas to migrate laterally.All the factors above constitute the hydrocarbon pathway systems a... |
