Abstract

In beach area, a series of the exploration and development technology is mainly based on seismic data due to the lack of well data and the distant spacing between the wells. Whether the geological model can meet the needs of early development is required evaluation. As the special ground and underground geological conditions and the difficulty of thin interbedded reservoir prediction, one of the key technologies is geological modeling based on seismic data. Taking Chenghai oilfields Ⅱ area as an example, three-dimensional reservoir modeling technology with cooperation of seismic attributes, seismic inversion data and logging data, integrates seismic data and description of the geological drilling features in the plane, and in vertical further characterizes the vertical reservoir characteristics on the basis of the inversion data, so as to approach the logging scale. This method of three-dimensional integrated modeling is suitable for thin interbedded sand\|mud projections. Studies on the geological model evaluation of the thin alternating layers show that the thin alternating layers are comparatively developed in beach area. The method of combining wells data and seismic data is adopted in geological modeling. The lithfacies model of the thin interbedded layers is analyzed in plane and vertical accuracy, and the lithfacies model which consistents with the geological recognition is optimized.
