| Since 2005, Xinli Oilfield Block Ⅵ has carried out researches on sedimentary microfacies of small layers、the study of distribution of oil sand, and the qualitative study of the distribution of remaining oil, playing a positive role to guiding block implementation phase to improve the development effect. But now Xinli Oilfield Ⅵ block is in a high water cut development stage. Original using small layer unit to analyze reservoir characterization has been far from meeting the needs of oil field development and production. Now that this period of the remaining oil distribution is extremely complex. It was highly dispersed state. An urgent need for research in the thick sandstone layer barrier sandwich and developmental status, the use of fine water flooding Exploiting plan to guide the development of adjustment,It is necessary to Fuyang reservoir characterization study of single sand body, genesis of thin interlayer single sand body inside, the type and development characteristics research and analyze.With sequence stratigraphy theory, the principle of "comparative cycle, hierarchical control", combined with regional iconic formations, the layers group and the small layer divide and contrast. Using of core data and log data Single well log analyze and research. Further research and analyze the small plane distribution layer deposition microfacies and cross-sectional shape. Using core laboratory analysis of the data blocks were logging physical parameters analysis, respectively, interlayer and compartment layer identify on the basis of small layers. Portray interlayers and compartments in the plane, According to the distribution range of interlayers and the exhibition on the plane with the small layer deposition micro, As a guide for the Fine characterization study of single sand body and the property Analysis of the distribution of single sand body, practical application of water distribution study is on the basis of this. In order to solve the contradiction of water flooding. |
