Oil And Gas Transmission System And Its Controling Effect Of Fuining Formation In Jinhu Sag

The Jinhu sag is rich in oil,but the complex structure of the fault is difficult to explore.To increase reserves,from Determining the " starting point"," essential period","transmission system "," end point" four comprehensive aspects,analysing the controling effect of transport system.Evaluating source rock,clarifing the period of accumulation,and determining the migration pattern of ancient and modern oil and gas.Analyzing the composition of the transmission grid in each region,evaluating the transmission elements and studying the distribution characteristics of the transmission elements,the transmission performance and the combination style of the transmission.Then,by analyzing the distribution characteristics of oil and gas,combined with the type of transport system and the distribution law,the hydrocarbon migration and transport mode and oil and gas enrichment law are clarified.Finally,the Four-in-One carries out a comprehensive analysis of the matching of reservoir elements and the evolution of accumulation.The Jinhu sag transport mode mainly includes direct single-transmission type,lateral far-source fault-sand body interaction step type,lateral near-source sand body-fault-sand body anti-Z shapeand and steep slope deep fault-sand body "F" type of transport four categories.Steep slope deep fault--"F" type of sand body makes the reservoir longitudinally stacked,and the reservoir is scattered and beaded in the plane,the vertical migration distance is the farthest,and the reservoir is along the fault.Beaded distribution.The direct-row single-transportation type in the source allows the oil and gas to be discharged directly to the reservoir.The reservoir has a single layer and is mostly developed in the E1f22 reef beach and the beach sand dam.The plane distribution is phased.Lateral far-source fault-sand body interactive step-type transport and lateral near-source sand body-fault-sand body anti-Z-shaped transport mainly transport oil from the hydrocarbon generation high potential area to the slope zone andthe inherited highland,which is distributed It is distributed in fish scales along the e direction of migration.
