Abstract:

For the fractured carbonate reservoir,fractures are effective reservoir space and primary channels. But the development
of fractures is complex and the reservoir has strong heterogeneity. The normal geological modeling methods are
not applicable to the fracture modeling. This paper takes X Oilfield in the Middle East Region as an example and establishes
the technology of fracture modeling on a scale of fracture zones,medium-size fractures,and small-size fractures based on
convergent multi-source information including geology,well-logging,seismic,and dynamic data. It is first proposed by the
authors that the fracture reservoir facies model is established on the combination of the deterministic model and stochastic model
method. Under the constraints of facies model,the development intensity bodies at different scale of fractures are established.
Finally,a discrete fracture network(DFN)model and fracture property model are generated by means of DFN modeling and
parameter field equivalence. In general,this paper discusses and studies a set of fracture modeling method converging with
multi-source information on the basis of different scale of fractures for the complex carbonate reservoir.
