[Abstract]:In this paper, the structural evolution characteristics, fault distribution characteristics, sedimentary characteristics and reservoir characteristics of the lower member of Jiufutang formation in Naiman Oilfield are carried out, the reservoir control factors are analyzed and the reservoir types are determined. Since the beginning of the project, we have actively collected and sorted out the data, clarified the geological tasks, determined the research route and key technologies, carried out solid and effective work, and successfully completed the tasks on schedule. On the basis of understanding and mastering the regional geological conditions and previous research results, the three-dimensional seismic data are explained in detail, and the favorable reservoir distribution is predicted by seismic inversion and reservoir prediction technology, and the trap is comprehensively evaluated. Choose the favorable position of the trap. The following research tasks have been completed: (1) formation correlation and division: the formation division and correlation of all kinds of drilling in the working area are divided into sandstone formation level; (2) structural research: combined with drilling, logging, logging and oil test and production test data, the comprehensive interpretation of three-dimensional seismic data is carried out, and the fault distribution characteristics of the lower member of Jiufutang formation and the top structural evolution and trap of each reservoir group are carried out. (3) study on sedimentary facies: the distribution of the phase zone of the main oil-bearing sand bodies is studied; (4) Reservoir characteristics research and reservoir inversion: comprehensive evaluation of reservoir, establishment of oil and water layer discrimination standard, logging secondary interpretation, and use of wave impedance inversion technology to predict the distribution of oil-bearing sand bodies in favorable areas. Carry out reservoir modeling research; (5) study on reservoir characteristics: study the controlling factors of the reservoir in the lower ninth section, determine the reservoir type and calculate the reserves.
