| In this paper, fine reservoir research is carried out, based on the present developmentproblems of Ying8block. The stratum subdivision grid model is established by choosing thecomparative markers and stratigraphic classification, and Ying8fault block7-15layersystem is subdivided from42original small layers into63original small layers, which playsan important role in guiding the flood pattern; Based on section map created by the seismicspectrum adn3D prestack interpretation technology, fault strike, changes in dip, as well as themicrostructure of small top layers is classified.Well logging facies and sedimentary faciesmodel are established, through core observation and logging facies analysis, and riverbedplan of sedimentary microfacies is analyzed. Four property relationship and secondarylogging interpretation is carried out, logging data standard and hole-permeabilityinterpretation model are established, in the evaluation of the effect of reservoir petrology,pore structure, clay minerals, as well as depositional time unit layers distribution to reservoirheterogeneity, and interlayer, plane and vertical heterogeneity is clear, and reservoirheterogeneity on development effect and residual oil distribution control are expounded inthis paper; Through fine geology research and method of combining deterministic modelingand stochastic modeling, using Petrel, Ying8fault block7-15layer system of reservoir finegeological model is established, the average mesh size is40m×40m, total grid number is434565, which meets the needs of late fine geological research and reservoir engineeringresearch. Microscopic distribution feature of remaining oil, formation mechanism andcontrolling factors of the distribution of the Ying8block is studied, though the structure andformation, reservoir parameter modeling, and development history, development indexmatching, and residual oil distribution of the block is known, which has guiding significancefor the next well pattern arrangement and block adjustment. |
