Abstract:
Based on fault and trap development history, reservoir saturated pressure, hydrocarbon-generated and hydrocarbon-expulsed process of hydrocarbon source rock, reservoir fluid inclusion homogenization temperature, the formation stages of oil-gas reservoirs in Puwei Subsag, Dongpu Sag are discussed, and calculating the formation stages of oil-gas reservoirs with saturated pressure should be combined with burial history for the area, in which the denudation is thicker. The results show that the accumulation phases of oil and gas reservoirs in Puwei Subsag are divided into two phases, Late Paleogene phase and Late Neogene-Quaternary phase; the petroleum accumulation phases in the oil and gas reservoirs are different between the eastern and western reservoirs; hydrocarbon charging times in the eastern reservoir are Late Paleogene phase and Neogene-Quaternary phase, but the time in the western reservoir is only Late Neogene.
