Nanpu oilfield is located south of the Nanpu depression,development Nanpu NO.1-NO.5 favorable structural zone with structural inheritance and development, around Nanpu depression major oil source second concave distribution of reservoir-cap combination of favorable conditions,traps are well developed,the characteristics of rich oil and gas resources.Nanpu oilfield has entered the current exploration evaluation and development program design phase,the previous exploration results indicate that the Nanpu oilfield is a large oil field.In this thesis,the basis of three-dimensional seismic data,drilling,geology,well logging with the test oil test data combined to carry out stratigraphic correlation, reservoir characteristics,fine structural interpretation and reservoir prediction and so on.The implementation of the fine structure,reservoir,accumulation and distribution of oil on the basis of such work to search for the target block.By enabling target block to be fine by the characterization,to carry out oilfield drilling wells and geological proof design.Closely integrated with production,drilling carried out to explain the work,the results continue to be applied to construct a new well to explain them,constantly improve the understanding of the underground geology,exploration and development wells in time for deployment and provide the basis for adjustment.Structural interpretation by region,implemented 1 to 5 out of Minghuazhen group structure - a bottom sand layer 7 forms the overall structure and spatial distribution of faults.Favorable target areas on the main oil-bearing layer fine structural interpretation,a total of 295 traps in the implementation of favorable layer, layer trap area of 785.2 km~2,for the exploration and development has provided a beneficial support.In the fine structural interpretation based on the favorable target areas through fine reservoir characterizations of the implementation of a favorable target areas the distribution of main oil reservoir in order to target wells to provide a solid basis for the deployment.Nanpu 1-5,the region structural seismic attribute and reservoir prediction,the implementation of the Lower Tertiary section of the eastern section of sand deposition distribution rules.Nanpu 1-5,in the shallow structure Minghuazhen,Guantao group and the East section of the fluvial delta sediment good reservoir properties,reservoir thickness of the large,wide distribution,from the Lower Tertiary oil source form xiasheng the combination of storage-type reservoir,oil and gas distribution is controlled by structure,the fault is the controlling factor, low-amplitude anticline reservoir block(nose) structures the main reservoir.In deep East Erduan,East three sections reservoir is mainly fan-delta front deposits,formed mainly of self storage reservoir from the combination of reservoir structure and reservoir distribution by two factors control the formation of structure - rock oil possession.Studies show that the South through the Fort 2,three times in a concave structure among the eastern,oil source conditions are good,faults and good in the shallow reservoir,three in the area developed anticline zone is favorable for hydrocarbon accumulation area.
