The Comprehensive Study Of Integration Of Wells And Seismic On Structure And Sand Body Of Sand Group Ⅰ-Ⅳ Of Putaohua In Seven-East Test Area Of Sa South

For the late stage in the development of oilfield, the implementation of micro structure on the late development effect improvement, adjustment of injection production relation is especially important. The study of seven-East Test area of Sa South has entered the late high water cut development stage, fine structure of the research work is particularly important.Through logging curve optimization of 3-D seismic data processing,fine production of the synthetic seismograph, and accurate tracing of horizons,the application layer between the trends method. According to the amplitude, phase or continuous, waveform similar to three basic principles, of the major reservoirs in seven-East Test area of Sa South four layer 9 time units for accurate tracking and characterization. Using observation method and coherent body of law attributes, the method and technology of large fault were to identify and characterize,and the first observation of browsing 3D data slices then waveform difference variant and a 3D browsing method were used to identify and characterize the minor faults, and the combination of logging curve of fault location verification and correction,final implementation of accurate fault location and scale. And according to the velocity field correction made of putaohua top T0 diagram and structure diagram. We identify the two small broken nose in structural map. According to the structural interpretation of the results, we can recognize the fault system can not only optimize development scheme,supplementary guide adjustment wells,wells high and large displacement well deployment,improve near the fault injection production system of comprehensive adjustment, transition zone extending well distribution Plan Preparation and implementation,provides a favorable basis, for later high water cut stage of sustainable development, what is controlled by the faults and movable remaining oil enrichment zone has provided a guarantee.Based on the analysis of the experimentation area faces sand body distribution scheme to extract and identify the properties of sand body. Mainly adopts the slice method,multi-attribute fusion,phase transformation, seismic faces classification,frequency dividing stratigraphic section method attribute extraction, finally sand body identification degree better,the main reservoir sand body identification with rate reached more than 80%,the graphs property accurately on later further development to provide a force of earthquake security.
