Abstract:

Based on the optimization method of integral fracturing parameter of the homogeneous geological model or conceptual
model，in which the reservoir heterogeneity and distribution of sand bodies are not considered，hence，there is a poor
match between optimization results and reservoir. To solve the problem，a fine reservoir 3-D geology model was applied to
conduct fracture-parameter-optimization research. By the fine geological modeling technology with consideration of the change
of reservoir properties and sand body distribution in the plane and longitudinal direction，the fine 3-D geology model has been
established. According to the formation coefficient and the layer distribution，reservoir types have been divided. For different
types of reservoirs，the optimization of integral fracturing parameters was conducted which was combined with production models
and economic evaluation mode. Finally guiding plates for integral fracturing parameters have been built. Because the object
was subdivided，the optimal fracture parameters of the block is not constant which alters with the change of reservoir types
and the results is more realistic. The achievement of this research is of great importance to the guidance of integral fracturing
design.
