Fine Structural Interpretation And Reservoir Prediction Of Fuyu Oil Layerat Xingnan Area

In order to implement a more accurate structure characteristic, reservoir characteristics and distribution of sand of Xingnan aera, we research the structure and reservoir characteristics use the seismic data with the prestack time migration technology to meet the needs the upgrade of reserves.The thesis has completed the comparison of stratigraphic framework, interpretation of fracture characteristics, structural characteristics, tectonic evolution history, using the three-dimension seismic interpretation technology,coherence cube technique and attribute analysis。We have ascertained the Fuyang reservoir group and each sandstone structure of top form,analyzed the development characteristics and classification of faults,and studied the development,and evolution of major faults.The other major work of the thesis is using attribute analysis, waveform cluster analysis, and wavelet transform techniques to analyze the Fuyu reservoir microfacies and predictethe effective thickness of 8 oil layers. Analyze reservoir lithologhic traps in various oil reservoir, identify and evaluate the hydrocarbon accumulation, according to the tectonic features, sedimentary characteristics, interpretation results of lithology and geological features of oil, and so on.In the paper, identify the various types of traps, sediment characteristics and the effective distribution of sand of Fuyu oil layer. The favorable areas were predicted combined with the oil exploration wells in the test results and oil/gas accumulation, etc. Comprehensive study the relationship of fault, structure, ancient construction and sand with oil/gas accumulation, optimize the favorable block and provide advice wells.
